XFX RX 470 Overheating

Guys, I have an RX 470 from XFX, and it overheats BAD. It goes up to 95ºC when playing "lighter" games like Kovaak's and CS:GO, but in Fortnite doesn't get that bad: about 85ºC. I have 4 fans, 1 behind for exhaustion, 2 in the front for bringing cool air, and 1 in the front for exhaustion as well. I already put the GPU fans speed on max, but it doesn't help at all, it just makes the PC really, really loud. Have cleaned it twice, last time a few weeks ago, and changed the thermal paste. Does anyone know why it gets hotter on games that are lighter then Fortnite, and how to fix it being so hot? I would really appreciate it.
PS: I bought it used from Amazon for 100$ 1 year ago, but it wasn't used for mining bitcoins. And it is not overclocked.

Which is the most important hardware to mine cryptocurrency?

Crypto mining equipment is specifically designed to solve blockchain hash functions at a faster rate than other hardware solutions. Traditional computers are built with a processor known as a Central Processing Unit (CPU), which is designed to compute the functions needed for a standard computer.
Alternatively, mining hardware is built with different, more advance processors. Yet, these aren’t just high-powered computers. Crypto mining equipment is more efficient than typical hardware at solving computational hashes required to successfully mine blockchains.
MINING HARDWARE DETAILS
There are several things to look out for when it comes to purchasing cryptocurrency mining hardware and equipment.[1]
First, these machines must not just be powerful, but energy efficient as well. Since the number one cost in crypto mining is electricity, a good piece of mining equipment must consume less power while still maintaining its high-powered usage. This makes a key factor in crypto mining hardware hashes per second per watt of power, which determines how much power is consumed for a given amount of hash power.
Second, because cryptocurrency mining is done 24/7/365, the equipment used to mine must be able to operate on a continuous basis. This means, equipment is designed for optimal cooling so as to not overheat from continuous use, as well as setting up equipment in a way which will allow for the most optimal cooling. If you are unsure how this can be done it may be best to outsource the installation and hosting of your mining hardware to a third-party provider with the proper tools and resources to service mining equipment.
TYPES OF MINING HARDWARE
There are three types of mining hardware: GPU, FPGA, and ASIC. The type of hardware used is dependent on the blockchain being mined. While ASIC-based hardware may be the most powerful for some blockchains (such as Bitcoin), they are rendered almost useless in other blockchains (such as ZCash) whose hashing algorithm is designed to be resistant to ASIC hardware.
Choosing the correct piece of mining hardware is one of the most important parts of cryptocurrency mining, as the wrong choice could result in a significant loss of potential profits and time.
All in all, it has become clear over the past several years that cryptocurrency mining hardware is necessary for anyone looking to make a profit in mining. Determining which piece of mining equipment is most suitable for your needs is dependent on many factors such as your budget and the blockchain being mined.

A story from a cloaky camper and an attempt to build a beast mode multi-boxing server.

21/04/2018
Hello Nerds!
 
Some of you may know me, some may not. Those that do will know I offer cloaky camping services over new eden. I do camping contracts / extort renters and focus my time hunting botters when the contracts are quiet. I offer PvP entities access to my cyno network to get dank kills and big escalations. From super carriers to Rattlesnakes.
 
The thing that got me into camping was hunting bots back in the dronelands a few years ago. I realised the most effective way to hurt them was to camp them 23/7, follow them around using locator agents. Eventually they had to rat with me in system. When they did I setup bubble traps etc and dropped blops and cleaned them up.
 
The 2nd thing I love about cloaky camping is the ability to counter Alliances (i feel its overpowered) intel channels / networks. Think about it. They have multiple intel toons dotted around the entrances to their pipes reporting hunters coming into the pipe allowing the PvE players to warp off and safe up. They even use external programs to collect this intel and give audible alerts. Cloaky camping is just the polar opposite. Dotting toons in their ratting pocket and giving me intel on whats going on in their system. As long as local chat exists so will cloaky camping. I'm pretty confident CCP share the same thought.
 
People probably think cloaky camping is easy. You are wrong. The prep work and behind the scenes work that goes into it is pretty immense. You are about to find out.
 
The hardware i'm currently running the 60 clients on is as follows:
 
Camper1: Screenshot of 30 Clients Layout
Camper2:
 
How do you pay for 60 toons
I started with 10 campers and made ISK by other means. When I made new campers I invested ISK and started to Skill extract and plexing the toons. I also make a decent amount from people who pay me to camp others.
 
The Setup  
I manage the clients window positions and CPU allocation with ISBOXER. Its legal to use as long as you don't use input broadcasting. I boot up the clients with ISBOXER EVE Launcher. I copy the window positions / chat channels etc over using garpaui. I use remote desktop to manage the clients light cynos etc.
Example here
 
On both motherboards I had to under clock the processors as they were drawing too much power from the motherboard and causing the chipset to overheat. I think these motherboards are not beefy enough to support these 8 core processors. It caused the CPU to throttle reducing the clock speeds to 1.3Ghz and causing lag issues. I solved this problem by reducing the clock speed from 4Ghz to 3.6Ghz and reducing the CPU voltage. This reduced the heat by a really good amount and stopped the problems.
 
However, Me being me I wanted to expand and the camping pcs were running at full chat. So I needed a better piece of hardware to host these 60+ clients. So, while at Fanfest, I bidded on this R820 Server on ebay and won!
 
Specs:
 
The hardware should be able to support multiple clients. However i'm not too sure how eve is going to behave when I try and open 60 instances all in one OS. I have set myself up for a hell of a challenge! However, I feel like I got a pretty good deal on the server and DELL hold their value. I'm sure I can re sell it if the project fails.
 
Things to work out:
 
Things I will teach you guys
 
I'm learning too so your help input would be awesome! First question. Shall I just update this reddit post each time or create some sort of blog?
Old AMD FX Rigs
New Kit / with various bits I gathered to get started
 
Update 23/04/18
I have made some decent progress on this crazy project. I will give some breif updates here. I will get a blog up and running to post full details with how to's etc. Its probably way to long for reddit.
 
I have successfully installed some GPU's into the R810 AMD R9 280x and Nvidia GTX 970. I soldered some PCI-E cables to the PDB and it worked fine. The GTX sits nicely in the chassis however, the R9 280X is external atm using a PCIE x1 to x16 riser (from my bitcoin mining). Also I have managed to enable and use them both with passthrough in ESXI 6.5. Yes the GPU works with a x1 adaptor. WTF!
 
Freezing Problem with a single os install
If I try and run more than 40 clients in a single OS I the system freezes when loading up client 41. I have tried the following:
I cannot see why it is freezing. Is there any way to gather logs for the client? It doesn't appear to be a resource problem. Plenty of RAM / CPU and HDD isn't going crazy.
 
Here are some pics of the current progress:

How do I mine Dogecoin?

How do I mine Dogecoin?
Let’s take a lucky guess that you’re here today because you’ve heard a lot about cryptocurrencies and you want to get involved, right? If you’re a community person, Dogecoin mining might be the perfect start for you!
Bitcoin was the first in 2009, and now there are hundreds of cryptocurrencies. These new coins (that operate on their own native blockchain) are called altcoins or alternative coins. One popular altcoin is Dogecoin. It can be bought, sold and traded, just like Bitcoin. It can also be mined!
So, what is Dogecoin mining?
You’ll know what hardware and what software you need to get started. You’ll also know whether or not Dogecoin mining is for you!
So, where would you like to start? The beginning? Great choice. Let’s have a quick look at how Dogecoin got started.
A (Very) Short History of Dogecoin
In 2013, an Australian named Jackson Palmer and an American named Billy Markus became friends. They became friends because they both liked cryptocurrencies. However, they also thought the whole thing was getting too serious so they decided to create their own.
Palmer and Markus wanted their coin to be more fun and more friendly than other crypto coins. They wanted people who wouldn’t normally care about crypto to get involved.
They decided to use a popular meme as their mascot — a Shiba Inu dog.

https://preview.redd.it/rymnyyz1iil31.png?width=303&format=png&auto=webp&s=f138e3fe56eef9c6b0e7f49b84fefc41fb83e5aa
Dogecoin was launched on December 6th, 2013. Since then it has become popular because it’s playful and good-natured. Just like its mascot!
Dogecoin has become well-known for its use in charitable acts and online tipping. In 2014, $50,000 worth of Dogecoin was donated to the Jamaican Bobsled Team so they could go to the Olympics. Dogecoin has also been used to build wells in Kenya. Isn’t that awesome!
Users of social platforms – like Reddit – can use Dogecoin to tip or reward each other for posting good content.
Dogecoin has the 27th largest market cap of any cryptocurrency.
Note: A market cap (or market capitalization) is the total value of all coins on the market.
So, Dogecoin is a popular altcoin, known for being fun, friendly and kind. It’s a coin with a dog on it! You love it already, don’t you?
Next, I want to talk about how mining works…
What is Mining?
To understand mining, you first need to understand how cryptocurrencies work. Cryptocurrencies are peer-to-peer digital currencies. This means that they allow money to be transferred from one person to another without using a bank.
Every cryptocurrency transaction is recorded on a huge digital database called a blockchain. The database is stored across thousands of computers called nodes. Nodes put together groups of new transactions and add them to the blockchain. These groups are called blocks.
Each block of transactions has to be checked by all the nodes on the network before being added to the blockchain. If nodes didn’t check transactions, people could pretend that they have more money than they really do (I know I would!).
Confirming transactions (mining) requires a lot of computer power and electricity so it’s quite expensive.
Blockchains don’t have paid employees like banks, so they offer a reward to users who confirm transactions. The reward for confirming new transactions is new cryptocurrency. The process of being rewarded with new currency for confirming transactions is what we call “mining”!

https://preview.redd.it/rcut2jx3iil31.png?width=598&format=png&auto=webp&s=8d78d41c764f4fe4e6386da4f40a66556a873b87
It is called mining because it’s a bit like digging for gold or diamonds. Instead of digging with a shovel for gold, you’re digging with your computer for crypto coins!
Each cryptocurrency has its own blockchain. Different ways of mining new currency are used by different coins where different rewards are offered.
So, how do you mine Dogecoin? What’s special about Dogecoin mining? Let’s see…
What is Dogecoin Mining?
Dogecoin mining is the process of being rewarded with new Dogecoin for checking transactions on the Dogecoin blockchain. Simple, right? Well no, it’s not quite that simple, nothing ever is!
Mining Dogecoin is like a lottery. To play the lottery you have to do some work. Well, actually your computer (or node) has to do some work! This work involves the confirming and checking of transactions which I talked about in the last section.
Lots of computers work on the same block of transactions at the same time but the only one can win the reward of new coins. The one that earns the new coins is the node that adds the new block of transactions to the old block of transactions. This is completed using complex mathematical equations.
The node that solves the mathematical problem first wins! It can then attach the newly confirmed block of transactions to the rest of the blockchain.
Most cryptocurrency mining happens this way. However, Dogecoin mining differs from other coins in several important areas. These areas are;
  • Algorithm: Each cryptocurrency has a set of rules for mining new currency. These rules are called a mining or hashing algorithm.
  • Block Time: This is the average length of time it takes for a new block of transactions to be checked and added to the blockchain.
  • Difficulty: This is a number that represents how hard it is to mine each new block of currency. You can use the difficulty number to work out how likely you are to win the mining lottery. Mining difficulty can go up or down depending on how many miners there are. The difficulty is also adjusted by the coin’s protocol to make sure that the block time stays the same.
  • Reward: This is the amount of new currency that is awarded to the miner of each new block.
Now, let’s compare how DogeCoin mining works compared to Litecoin and Bitcoin…
Mining Comparison
Bitcoin uses SHA-256 to guide the mining of new currency and the other two use Scrypt. This is an important difference because Scrypt mining needs a lot less power and is a lot quicker than SHA-256. This makes mining easier for miners with less powerful computers. Fans of Litecoin and Dogecoin think that they are fairer than Bitcoin because more people can mine them.
Note: In 2014, Litecoin and Dogecoin merged mining. This means they made it possible to mine both coins in the same process. Dogecoin mining is now linked with Litecoin mining. It’s like two different football teams playing home games in the same stadium!
Mining Dogecoin is a lot faster than mining Litecoin or Bitcoin. The block reward is much higher too!
Don’t get too excited though (sorry!). Dogecoin is still worth a lot less than Bitcoin and Litecoin. A reward of ten thousand Dogecoin is worth less than thirty US Dollars. A reward of 12.5 Bitcoin is currently worth 86,391.63 US Dollars!
However, it’s not as bad as it sounds. Dogecoin mining difficulty is more than one million times less than Bitcoin mining difficulty. This means you are much more likely to win the block reward when you mine Dogecoin.
Now I’ve told you about what Dogecoin mining is and how it works, would you like to give it a try?
Let’s see what you need to do to become a Dogecoin miner…
How to Mine Dogecoin
There are two ways to mine Dogecoin, solo (by yourself) or in a Dogecoin mining pool.
Note: A Dogecoin pool is a group of users who share their computing power to increase the odds of winning the race to confirm transactions. When one of the nodes in a pool confirms a transaction, it divides the reward between the users of the pool equally.
Dogecoin Mining: Solo vs Pool
When you mine as a part of a Dogecoin pool, you have to pay fees. Also, when the pool mines a block you will only receive a small portion of the total reward. However, pools mine blocks much more often than solo miners. So, your chance of earning a reward (even though it is shared) is increased. This can provide you with a steady new supply of Dogecoin.
If you choose to mine solo then you risk waiting a long time to confirm a transaction because there is a lot of competition. It could be weeks or even months before you mine your first block! However, when you do win, the whole reward will be yours. You won’t have to share it or pay any fees.
As a beginner, I would recommend joining a Dogecoin pool. This way you won’t have to wait as long to mine your first block of new currency. You’ll also feel like you’re part of the community and that’s what Dogecoin is all about!
What You Need To Start Mining Dogecoin
Before you start Dogecoin mining, you’ll need a few basics. They are;
  • A PC with either Windows, OS X or Linux operating system.
  • An internet connection
  • A Shiba Inu puppy (just kidding!)
You’ll also need somewhere to keep the Dogecoin you mine. Go to Dogecoin’s homepage and download a wallet.
Note: A wallet is like an email account. It has a public address for sending/receiving Dogecoin and a private key to access them. Your private keys are like your email’s password. Private keys are very important and need to be kept completely secure.
There are two different types; a light wallet and a full wallet. To mine Dogecoin, you’ll need the full wallet. It’s called Dogecoin Core.
Now that you’ve got a wallet, you need some software and hardware.
Dogecoin Mining Hardware
You can mine Dogecoin with;
  • Your PC’s CPU: The CPU in your PC is probably powerful enough to mine Dogecoin. However, it is not recommended. Mining can cause less powerful computers to overheat which causes damage.
  • A GPU: GPUs (or graphics cards) are used to improve computer graphics but they can also be used to mine Dogecoin. There are plenty of GPUs to choose from but here are a few to get you started;SAPPHIRE Pulse Radeon RX 580 ($426.98)Nvidia GeForce GTX ($579.99)ASUS RX Vega 64 ($944.90)
  • A Scrypt ASIC Miner: This is a piece of hardware designed to do one job only. Scrypt ASIC miners are programmed to mine scrypt based currencies like Litecoin and Dogecoin. ASIC miners are very powerful. They are also very expensive, very loud and can get very hot! Here’s a few for you to check out;Innosilicon A2 Terminator ($760)Bitmain Antminer L3 ($1,649)BW L21 Scrypt Miner ($7,700)
Dogecoin Mining Software
Whether you’re mining with an ASIC, a GPU or a CPU, you’ll need some software to go with it. You should try to use the software that works best with the hardware you’re using. Here’s a short list of the best free software for each choice of mining hardware;
  • CPU: If you just want to give mining a quick try, using your computer’s CPU will work fine. The only software I would recommend for mining using a CPU only is CPU miner which you can download for free here.
  • GPU: If you mine with a GPU there are more software options. Here are a few to check out;CudaMiner– Works best with Nvidia products.CGminer– Works with most GPU hardware.EasyMiner– User-friendly, so it’s good for beginners.
  • Scrypt ASIC miner:MultiMiner– Great for mining scrypt based currencies like Litecoin and Dogecoin. It can also be used to mine SHA-256 currencies like Bitcoin.CGminer and EasyMiner can also be used with ASIC miners.
Recommendations
You’re a beginner, so keep it simple! When you first start mining Dogecoin I would recommend using a GPU like the Radeon RX 580 with EasyMiner software. Then I would recommend joining a Dogecoin mining pool. The best pools to join are multi-currency pools like Multipool or AikaPool.
If you want to mine Dogecoin but don’t want to invest in all the tech, there is one other option…
Dogecoin Cloud Mining
Cloud mining is mining without mining! Put simply, you rent computer power from a huge data center for a monthly or yearly fee. The Dogecoin is mined at the center and then your share is sent to you.
All you need to cloud mine Dogecoin is a Dogecoin wallet. Then choose a cloud mining pool to join. Eobot, Nice Hash and Genesis Mining all offer Scrypt-based cloud mining for a monthly fee.
There are pros and cons to Dogecoin cloud mining;
The Pros
  • It’s cheaper than setting up your own mining operation. There’s also no hot, noisy hardware lying around the house!
  • As a beginner, there isn’t a lot of technical stuff to think about.
  • You get a steady supply of new currency every month.
The Cons
  • Cloud mining pools don’t share much information about themselves and how they work. It can be hard to work out if a cloud mining contract is a good value for money.
  • You are only renting computer power. If the price of Dogecoin goes down, you will still have to pay the same amount for something that is worthless.
  • Dogecoin pools have fixed contracts. The world of crypto can change very quickly. You could be stuck with an unprofitable contract for two years!
  • It’s no fun letting someone else do the mining for you!
Now you know about all the different ways to mine Dogecoin we can ask the big question, can you make tons of money mining Dogecoin?
So, Is Dogecoin Mining Profitable?
The short answer is, not really. Dogecoin mining is not going to make you a crypto billionaire overnight. One Dogecoin is worth 0.002777 US Dollars. If you choose to mine Dogecoin solo, it will be difficult to make a profit. You will probably spend more money on electricity and hardware than you will make from Dogecoin mining. Even if you choose a Dogecoin pool or a cloud pool your profits will be small.
However, if you think I am telling you to not mine Dogecoin, then you’re WRONG! Of course, I think you should mine Dogecoin!
But why? Seriously…
Well, you should mine Dogecoin because it’s fun and you want to be a part of the Dogecoin family. Cryptocurrency is going to change the world and you want to be part of that change, right? Mining Dogecoin is a great way to get involved.
Dogecoin is the coin that puts a smile on people’s faces. By mining Dogecoin you’ll be supporting all the good work its community does. You’ll learn about mining from the friendliest gang in crypto. And who knows? In a few years, the Dogecoin you mine now could be worth thousands or even millions! In 2010, Bitcoin was worthless. Think about that!
Only you can choose whether to mine Dogecoin or not. You now know everything you need to know to make your choice. The future is here. So, what are you going to do?

I've started working on modifying the Vive wireless adapter for better passive cooling.

First and foremost: I voided my warranty, this is not a how to, this is an attempt to see if anyone else is working on a similar solution and to get as much input from as many people as possible. Please chime in if you have any thoughts on the subject. I have the Pro version, which means the adapter is under more strain, it's constantly at the bandwidth limit in most games.

I have no background in engineering nor am I in any way qualified to do this, but I did mine bitcoin back in the day and learned a lot about heat accumulation and dissipation. My proudest achievement was running a 6 GPU rig on my balcony for a year consecutively in Finland with the ambient temperature of -30c to +40c. Almost nothing ever caught fire :) This experience leads me to think that it's a bad idea to draw more power trough the headset, from the same battery for a fan. Also I have long hair and am downright afraid of adding a fan to my head.

I have begun to cut off some, not all of the, "plastic strips" covering the openings in the adapter. I intend to remove about half of them, every other to be exact, removing all seems like it could weaken the "chassis" too much. If that is not sufficient then I'll open the entire thing out and try to figure out if there are spots where small aluminum heat sinks could be added without interfering with the reception. What material would be the least interfering with the reception whilst having the greatest possible thermal conductivity? The answer is probably not metal at all?
Here's where I began, I intend to go back and smooth the edges, possibly with a soldering iron: https://imgur.com/a/smMdT7n

I'll try to post updates in comments as the chopping progresses, hopefylly we see some input before entirely "gut the sucker" :)

Anyone considering adding a fan might want to cut off the "plastic strips" covering the openings in the adapter from beneath the spot you intend to add the fan to, especially if you intend to glue the fan on to the adapter. Actually I can guarantee this will improve the (unknown to me) efficiency of your fan mod by a double digit %.

[edit1]
I have removed roughly half of the strips and done some testing, not enough to say anything conclusive, but the adapter seems slightly cooler after and during intense use. I did play a full battery's worth of Skyrim without seeing a grey screen, this has happened before, but not that often. I discovered the back "plastic strip" has a clip that's holding the enclosure together. Had I known this I would of not cut it, looks like it missing wont be a problem tough. I have clearly created openings that will gather dust, so from here on I'll make a routine of blasting the adapter with air duster from time to time. It's obviously also more vulnerable to liquids now, but I don't see any sweat getting in from the top and sides where the modifications are.

Has anyone opened the adapter up, does a teardown guide exist?

[edit2]
It just occurred to me that anyone using a fan mod would achieve greater efficiency by running a split usb cable, so the fan does not draw power trough the headset. If my current tinkering proves inefficient I will probably go this way myself. Having the fan pull air trough the top of the headset, rather than pushing it in.

[edit3]
10 hours of gaming in and I haven't seen a grey/blue screen yet. Apart from one IRQ error, those usually bsod my whole computer. Unfortunately I seem to be stuck on that front because my mobo's bios dosen't seem to include any IRQ settings at all.

[edit4]
Haven't seen a grey screen since the modifications, but my holodeck is in a room that gets no heating, so the ambient temperature has been 5-10c less than usual. So I'm pretty sure I have no valid findings to report atm. I will, only, continue working on the adapter as the problems re-emerge. Doing anything now seems like fumbling in the dark.
[edit5] Been slightly warmer so yesterday when I fired up Moss and turned the graphics options all the way up I experienced the first grayscreen that lasted longer than a second and did not recover on it's own after beginning modifying the adapter. This was after ~20 minutes of playing. So I proceeded on with the chopping, I promise pictures soon but atm there is no light, I have now cut all the strips on all the sides, 6 out of the 18 strips on the top mid part remain and 1/3 on the horn's remain. Please note that I've concluded that cutting the strips on the horns does absolutely nothing heat wise, so knowing what I know now I'd leave them be.

I'm about to attempt to overheat the thing with Moss next and if I succeed, I'll start looking at usb fans.

[edit5]
Did not overheat this time around, regardless I'm looking at fans. Optimal sizes seem like 5cm or 7.5cm diameter. As explained earlier I'll go for a "split cable" or "passthrough" to avoid running any extra current trough the adapter. I'm pretty sure no ones reading this, but I'll keep updating it and will re-publish if I feel like I've gotten the issue sorted. Not covering the button seems harder than anticipated, I should move it... but I don't feel comfortable doing that. I guess I'll order a bunch of fans and see what works out once I have them in hand.
Note to self: the added usb cable/'s should run under, not over the adapter. So that we don't introduce copper wires to block or hinder the signal. This means the minimum cable length is ~13cm. Arctic cooling can move 15.1 CFM / 25.7 m³/h @ 0.08 Sone (@ 1,200 RPM) with a 8cm fan. Settling for less than half of this would be madness. USB to 2 x 3/4-Pin PWM 5V USB Sleeved Dual Fan Power Adapter Cable exists, were not settling for less :) I orderedhttps://www.amazon.com/gp/product/B077PXJRTT/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 mainly because they did not attempt to screw me over with shipping costing more than the 800% markup product.
and https://www.arctic.ac/eu_en/f8-silent.html because they make the best products in the field. at 5v this runs at 400 rpm, completely silent and still shifting 5 CFM or 8.5 m³/h. If this proves inefficient I can try running it with a separate 9V battery, no speed is indicated for 9V, but that'd reach 700-800 RPM and increase the airflow at the same rate.
Still looking for usb male to male type a splitter (all male) these don't seem to exist : /
[edit6]
Gave a try using a soldering iron to smooth the openings and cut edges, not a huge success, but gets the job done.
https://imgur.com/a/8ZvZovl

[edit7]
Did some log digging, things are bad:
The latest log is three days old, it shows the adapter consistently hitting 80c and during one session, I suspect it's Moss, but can't be sure, it gets really bad:
" [2018-12-30 16:41:32.769 +2 0x28CC INFO LOG] (ControlCenter)Link Condition Change : peerSignalQuality = 4, performanceQuality = 3 [2018-12-30 16:41:33.807 +2 0x2898 INFO LOG] M_Temperature=84, R_Temperature=48 [2018-12-30 16:41:43.804 +2 0x2898 INFO LOG] M_Temperature=85, R_Temperature=51 "

87c that's not a safe amount of heat to attach to the top of your head. That's also a temperature that would kill a GPU if constantly reached.

Fan arrived, I got the size right, but can't proceed to test before the cable arrives. I did think of a lazy but promising way of testing ways to mount the fan: I'mma just ziptie it to the horns and experiment at different angles with wedges of cardboard to hold it. The fan weighs 71g and the plastic strips that I've removed total about 6g. I'm pretty sure I can shave off up to 10g from the fans plastic components once I decide on a mounting style/method. There'd probably be an another 2g to shave off by shortening the power cable, but in my case I'll need a friend to do it for me and I was thinking of shortening the power adapter cable to the bare minimum too so might as well stack the jobs. I'm also scrounging for a net of some sort to keep my hair out of the fan, that'll obstruct the airflow like a mf especially as I'm adding one to both sides... but I'm hopeful that the fan is overkill enough to still do the job and keep me cooler during Beat Sabre.

Getting Started with Bytecoin: A Beginner’s Guide

In this post, I discuss exactly what you need to start exploring cryptocurrency, particularly Bytecoin. It took me several days to learn this information through trial and error. Using information in this post, however, you should be able to start using cryptocurrency in less than a day. Specifically, I will discuss three things you must do to started, namely:
  1. Downloading a compatible wallet;
  2. Creating a .wallet file and syncing the wallet with the blockchain; and
  3. Getting Bytecoin by mining for it or purchasing it from someone who already has it.
In all honesty, these are the very basics of cryptocurrency, and you can apply the steps to almost any other currency, including Bitcoin. Similarly, I could write an entire post on how to configure your computer, so you reap the most amount of profits on Bytecoin UK, for example, but that is just beyond the scope of this post.
If, however, you find this post helpful, please donate BCN here: 21DUzLdrRHuX9A1d8P2NMSZFAo8XETxybEYjAhV3RdcmYePkCmjM9hoEVhPFQB4MofSeJPdjHhJSJRWjiBTyrY132LnDJT2
------------------------------------------------------Getting a Wallet----------------------------------------
The most secure way to store your Bytecoin is by installing a wallet, which is nothing more than a program that allows you to send and receive Bytecoin as well as mine for Bytecoin, on your laptop or desktop.
The best way to acquire the wallet is to visit the developer of Bytecoin’s website (i.e., https://bytecoin.org/downloads) and download it. Since Bytecoin is constantly being improved, I would recommend that you download the Beta version of the desktop wallet. Having just installed it myself, I know it's working just fine.
Once you download it, you will want to install it, and at this point, your anti-virus software may flag it as a virus, but it isn’t. It is 100% safe.
Next, you’ll want to create your wallet, which will require you to set a password. At the top of your wallet, click wallet and then create wallet, which should prompt you to enter a password. In creating a wallet, you'll notice that your wallet creates a .wallet file; you will want to save this somewhere safe, since it contains all of the information about your wallet. In other words, this is the file you can open to view your account.
As soon as you create the wallet, your wallet will begin synchronizing with the blockchain, which is a ledger of all of the transactions that have taken place with Bytecoin.
Depending on how fast your internet connect is, this process will take approximately 3 to 8 hours to complete, and it will take up a lot of your computer's resources, particularly its hard drive. This is completely normal, and once you go through this, you won’t have to do it again.
As soon as your wallet synchronizes with the blockchain, you will be ready to start sending and receiving Bytecoin. Similarly, if you do not sync your wallet with the blockchain, you will not able to send or receive Bytecoin!
Your Bytecoin address, which is the address at which you can receive funds from other people, is the long string of random characters toward the top of your wallet. If you click on it, it will automatically be copied to your clipboard.
Now, you’re ready to start sending and receiving Bytecoin and as well as mining for Bytecoin.
------------------------------------------------Acquiring Bytecoin--------------------------------------------
While there are several ways to acquire Bytecoin, I will discuss the two most reliable methods here. In essence, you can either use your computer to mine for Bytecoin, or you can purchase Bytecoin directly from someone who has Bytecoin already.
-------------------------------------------MinerGate---------------------------------------------------------
As for using your computer to mine for Bytecoin, I would recommend creating an account on MinerGate.com and downloading its mining software. As was the case for your Bytecoin wallet, your anti-virus may recognize the software as a virus, but it’s not.
Once you load the software, you simply put in same e-mail address you used to create the account on MinerGate.com and start mining.
As far as CPU mining goes, you will want to use less CPU power than you computer currently has available. For example, my processor has six cores, so I typically only use 5 cores to mine. If you only have a dual-core processor, I would recommend you only use one of the cores to mine. Otherwise, you can cause your machine to overheat.
To monitor my system, including its core and GPU temperature, I use Open Hardware Monitor (i.e., http://openhardwaremonitor.org/)
As soon as you mine 100 Bytecoins, you can then transfer them directly to your wallet. Note: If you are only using a limited amount of your computer’s resources, this can take as long as one month, and there are calculators on MinerGate.com that will help you determine how long it should take.
--------------------------------------------------Bytecoin UK------------------------------------------------
If you want to start earning Bytecoin within a few hours, you can also mine on the Bytecoin UK pool (i.e., https://bytecoin.uk/#getting_started).
On its website, you can download a miner that has a Graphical User Interface (GUI) and see the commands you need to use other mining software. For example, I use Claymore's CPU miner, so I enter the following commands in command prompt:
NsCpuCNMiner64 -o stratum+tcp://bytecoin.uk:3333 -u YOUR_WALLET_ADDRESS -p x
By entering your wallet ID on its website, you can check your mining statistics and payment history. In addition, you can also configure it so that you will receive payouts for every 5 BCN you mine. Note: MinerGate requires you to mine 100 BCN before you can transfer the BCN to your wallet, whereas Bytecoin UK only requires you to mine 5 BCN for a payout.
----------------------------------------------------------eBay-----------------------------------------------
If you don’t want to use your computer’s resources to mine Bytecoin, you can also purchase it directly from a seller.
In my experience, the most reliable way to buy Bytecoin is through eBay. There, you simply purchase Bytecoin from a seller who usually lists the methods by which he or she is willing to accept payment in the description of the post.
Typically, a seller will ask you to send your payment, as well as your Bytecoin address, to them via a message on PayPal.
As long as you send small amounts, your risk of being scammed is minimal, and personally, I have never been scammed this way.
So that’s it. Now, you’re ready to start using Bytecoin!

7GPU build is losing its mind freezing. Testing for failed parts is tedious

Feel free to laugh at my career ending $12,000 blunder.
I did have this whole thing stable for about 1 day, but now it's all gone to hell. I attempted a server rack mounted build similar to the Linus 7 gamers 1 PC video.
Parts List:
Observations:
Any thoughts? personal experiences to draw on? At this point, I'd settle for just random ideas? Should I try rolling the Bios from 3502 back to 3402? Maybe run all GPUs off external power and only the motherboard and CPU off a main PSU?

What the heck did you just hecking say about me, you little crum?

I’ll have you know I graduated top of my class in the BITcoin mining academy , and I’ve been involved in numerous secret raids on the etherium blockchain, and I have over 300 confirmed mainNet GRLC. I am trained in Crypto warfare and I’m the top miner in the entire Garlicoin discord. You are nothing to me but just another Amateur. I will wipe you the Heck out with precision the likes of which has never been seen before on the testnet, mark my Hecking words. You think you can get away with saying that GRLC Wont take off over the Internet? Think again, HECKER. As we speak I am contacting my secret network of GRLC Admins across the WORLD and your IP is being traced right now so you better prepare for the storm, Doughboy. The storm that wipes out the pathetic little thing you call A GRLC Main net miner. You’re Hecking done, kid. I can be anywhere, anytime, and I can Mine GRLC in over seven hundred ways, and that’s just with my Rasberry pi. Not only am I extensively trained in Internet trolling, but I have access to the entire arsenal of GITHUB and I will use it to its full extent to wipe your miserable GPU miner off the face of the continent, you little Heck. If only you could have known what unholy retribution your little “clever” comment was about to bring down upon you, maybe you would have held your Hecking tongue. But you couldn’t, you didn’t, and now you’re paying the price, you goddamn Amateur. I will Heck fury all over you and you Miner will Overheat in it. You’re Hecking done, kiddo.

(Dummies Guide) How to simultaneously run multiple instances of cgminer to control different GPUs whilst using BAMT.

In cgminer you cannot specify multiple values for gpu-threads. gpu-threads is a global per-instance setting, not a per-GPU setting. If you want to run 2 different values of gpu-threads, you need to run 2 instances of cgminer.
This guide will help you if, for example; you have a rig in which one or more of your cards run better with gpu-threads set to 1 and your other cards run better with gpu-threads set to 2 (or 3 or 4)
So I'm going to assume here that you're running a rig with 4 cards and you're already set up and mining.
I'm also going to assume that you know how to use nano. So let's say your cgminer.conf has the line "gpu-threads" : "2", Unfortunately your 4th card isn't giving you the hash-rate you're expecting from it or worse, you're getting hardware errors which lead to rejected shares.
(to see if you're getting hardware errors in BAMT, you need to be able to see what cgminer is actually displaying. To do this simply SSH to your rig, log in and type "screen -r". I won't go too into this to much but where it says HW: you don't want so see anything there, if you're seeing anything other than 0 then you have problems with your config. Now to detach from this screen you need to press "ctrl+A+D" this is very important, do not press q!)
Anyway, you know that the 4th card wants to run with "gpu-threads" : "1", but you can't do "gpu-threads" : "2,2,2,1", this will not work!
So to get 2 cgminers running, follow these steps:
  1. SSH to your rig, be logged in, and a super user. You should be seeing this: [email protected]:/home/user#
  2. Type "nano /etc/bamt/cgminer.conf" Add the line: "device" : "0-2", This is saying that this instance of cgminer will be controlling GPUs 0, 1 & 2. Save and exit (ctrl+x)
  3. Type "nano startcgminer.sh" This will create a new script that you will run later to boot up your 2nd cgminer. Now type "chmod u+x startcgminer.sh" and hit enter.
  4. Add your info. below is mine but you want to replace with the settings for your 4th card (gpu 3): (where it says "device 3" this is saying that this instance of cgminer will only run gpu 3 (4th card) and "remove-disabled" makes it so it won't display the other cards)
    export DISPLAY=:0 export GPU_USE_SYNC_OBJECTS=1 export GPU_MAX_ALLOC_PERCENT=100 export CGMINER_BIN=/opt/miners/cgminecgminer $CGMINER_BIN --scrypt \ -o miningpoolserver.com:3333 -u username -p password \ -o backupminingpoolserver:3333 -u username -p password \ -I 20 \ -w 512 \ --gpu-threads 1 \ --thread-concurrency 32765 \ --gpu-engine 990 \ --gpu-memclock 1500 \ --gpu-powertune 11 \ --gpu-vddc 1.025 \ --device 3 \ --remove-disabled \ --temp-cutoff 99 \ --temp-overheat 95 \ --temp-target 85 \ --auto-fan \ --gpu-fan 50-85 
    Note: Make sure there are no random spaces at the end of any of these lines and also make sure that the I for intensity is upper case.
    Now save and exit the script by hitting ctrl+x etc.
  5. type "screen -ls" and hit enter, you should see something similar to this:
    There are screens on: 4366.pts-1.bamt-miner (12/30/2013 08:00:56 PM) (Detached) 1 Sockets in /varun/screen/S-root. 
    So this is saying that there is currently only 1 screen running and BAMT is using it to run cgminer inside.
  6. Type "screen" and hit enter, it will come up with a load of text about screen, just ignore that and hit enter again. Now you are inside your new 2nd screen.
  7. Now type ./startcgminer.sh You should now see cgminer boot up and start mining with just gpu 3. To detach from this screen you need to hit ctrl+a+d.
And that's it, there should now be 2 screens running.
To check the other screen type "screen -ls" and hit enter, you should now see both screens running. Something like this:
There are screens on: 6349.cgminer (12/30/2013 08:08:35 PM) (Detached) 4366.pts-1.bamt-miner (12/30/2013 08:00:56 PM) (Detached) 2 Sockets in /varun/screen/S-root. 
To look at one screen type "screen -r 6349", to look at the other type "screen -r 4366" (remember to detach from screens using ctrl+a+d)
You should still be able to see info for the first 3 cards on BAMT's web UI and in fact I can still see the temp and load for my 4th card.
Please feel free to leave feedback, or let me know if I've missed anything.
I hope you found this guide useful and if you did please consider a small BTC donation :)

Software Review: CGWatcher by Justin Malone

I've been using it for over a month and let me tell ya about it: CGWatcher.
So basically, you can run CGMiner and sometimes it'll crash. Sometimes if a GPU card gets above 100 C, it will not only blue-screen my machine (spontaneous shut-down), it will actually lose the 2nd GPU (something 'snaps' with the drivers). In the past 24 hours, I have reinstalled windows about 8 times or so.
Tools like CGWatcher have become essential. Another reason would be that if overheat is detected in CGMiner, it will shut down the GPU, then re-enable it after the target temperature is reached (on my machine 75 or 85 C), but wait!!! Did I say that CGMiner would re-enable the GPU? Because in reality, it only says it re-enabled the GPU, and it will just sit there at 0.0 hash rate. Until you restart it.
Tools like CGWatcher therefore have become essential to litecoin and bitcoin miners.
Earlier versions of CGWatcher didn't switch back and forth from litecoin to bitcoin mining easily. I do not think this was a software issue, I believe that you have to use CGMiner to output your Config File, then choose that in CGWatcher. If you try to add scrypt mining from inside CGWatcher, it didn't seem to work well.
Whatever it was, now it is no longer a problem (again, if it ever was) to switch from litecoin to bitcoin mining.
The developer has made a lot of look and feel improvements, and as we speak it actually seems to be adjusting difficulty automatically (although I didn't configure it, I'm sure it's in a config page somewhere and isn't entirely unwelcome just yet -- it's just a surprise).
I left anonymous feedback to the guy to OPEN SOURCE IT. DAMMIT. This is 2013, and things should be open-sourced, so that other developers can make their improvements. However, this is a free country, and I am using it, and it seems to be working great. Though y'all might like to give it a whirl yourselves.

The Anatomy of Genesis Mining Rig

Crypto mania is taking the world by storm! From reaching a combined $600 billion market cap, to Bitcoin trading at $20k on some exchanges, there seems to be no stopping the rise of digital currencies.
There are many ways to cash in on the potential that crypto has to offer, one of them being mining. This is the process where each transaction or record on the blockchain network is verified. As a reward for their contribution to the network, the miners receive freshly generated cryptocoins.
The cryptocurrency mining process is extremely processor as well as power intensive, and can get expensive if tried individually at home. Not to mention, the mining process requires specialized hardware, which has to be set up by oneself along with the power supply to feed the hardware. Genesis Mining steps in here to make the whole process easier, allowing interested cryptocurrency community members to be part of the mining community without going through any of these hassles. On a mission to “democratize mining”, the company is providing accessible and affordable cryptocurrency mining solution to the masses.
Genesis Mining provides cloud-based mining services to small- and large-scale investors. Their mining farms already have all of the equipment set up. In fact, the platform has the best Bitcoin and Altcoin-mining hardware and software available and running already.
The representatives of Genesis Mining have recently taken an initiative through their “EvolveWithUs” campaign to explain cryptocurrency mining and their services in the sector to the general public to increase awareness about the process and the company’s offering.
What is a Mining Rig?
Stefan Schindler, CTO representing Genesis Mining offers a simple definition for the most crucial hardware in the mining operation by saying,
“A mining rig is basically a computer, but is stripped down to the minimum in terms of computing, and up to the maximum in terms of mining.”
The Evolution of Mining
Mining had previously been done on a computer’s processor. However, as the industry grew, so did its mining requirements. Processor mining took an enormous amount of power, and an alternative was eventually adopted — Graphic cards. Graphics Cards or GPUs, proved to be more efficient at processing transactions, and didn’t use nearly as much power, resulting in a classic ‘work smarter, not harder’ approach. Since then the industry has advanced, creating specialized hardware called ASIC miners. However, GPUs still play a vital role in mining some of the popular alternative cryptocurrencies (Altcoins) in the market.
The Structure of a Mining Rig
In appearance, it looks like your average computer mainboard. The key difference is that is filled with lots of GPUs. The USB port contains USBs holding the actual mining software, which is not stored on the processor. It also has plenty of connecting cables to make everything run.
GPU processing
In the case of Genesis Mining, their specialized mining rigs can hold about six GPUs each. The mainboards available on the market do not have the internal space or slots for all of these GPUs that goes into Genesis Mining’s version of mining hardware. This is where PCI risers come in, which are extension cables that allow the mainboard to be fitted with many GPUs. These risers also help with even heat distribution so that the rig doesn’t overheat.
The power supply unit is also fitted with a strong cable, and powers all of the GPUs and the mainboard.
The company manufactures, stores and operates the mining rings at their mining farms in Iceland and other locations. These equipment can be quickly and efficiently assembled and are completely mobile for added convenience.

A beginner question about running a gpu 24/7 for mining.

Hey guys,
I've recently (last week) started mining bitcoins with pocblm on my sapphire HD5850. I'm putting out an average of 270MH/s. This is not too bad for my expectations, but since I run it only 2-3 hours a day I'm not really making any progress on the bitcoins (about 0.3 so far in total, over 5 days).
I'm thinking about running the card about 12h a day but I don't really dare to. Currently I set the fan speed manually to 100% to keep the temperatures in the 70-75°C range, which I'm told is a safe temperature. I can't sleep with the fan on that speed though so mining at night is not really an option for me. I'd have to run it during the day when I'm not around, but I don't dare to leave my pc running with a gpu that's spinning a fan at 100% and hovering around the 75°C mark.
What are the risks here, long- and shortterm? What could happen to my gpu if it ran for, say, at that temp for 6 hours straight, or more? I originally built this system around christmas because my last pc died and I wanted to play some games and have a medium-end pc for the next couple of years. So I don't really want to risk too much (I'm not a very rich guy), obviously.
Is there a chance, for example, that the fan could break down and my gpu would overheat? Or am I being too much of a paranoid parrot atm? Any advice on the possible risks or about some precautions I could take are very welcome.

An alternative to, heat problems and energy problems but I need help.

Hey guys. I am on my way to break through the barrier on what is productive in the sense of bitcoin production.
First is heat.
My plan is to connect and regulate the heat from bit mining to my hot water tank (possibly two tanks as the lower tank would overheat the chip) hmm... Do i make sense?
I would like to get water coolers to attach to the GPU and CPU and dump the water to the hot water tank... Okay, it may sound ridiculous but I have and manage an apartment that has 8 room mates, trust me, that hot water tank is a burden on my electricity bill. Having enough electricity and GPU units to fully heat a hot water tank is essentially my dream. Why?
I have a gas fireplace and I would like to somehow run that sucker to generate electricity, possibly and hopefully enough to run my bit farm.
My current budget at the moment is roughly $2000 for any changes or modds.
If anyone has any ideas or wants to collaborate with me, let me know. I am dying to escape the electric bill and see some seriously awesome options.
This guy had an awesome idea back in 07 and I wanna change and expand on it.
Also, I have about 20 bit coins I can cash in, but I would rather hoard them.

[modpost] Possible wiki page, something I call "All about miners," covering things from basic terminology to miner config files and overclocking.

What is a miner?
A miner is a computer set up to solve cryptographic hashes in the litecoin network. Once a clump of these hashes, or a block, is mined, litecoins pop out! It's like opening a box of chocolates, except you know what you're gonna get :) Miners also handle transaction confirmations, making sure no single coin is double-spent.
Setting up your computer to be a miner
What kind of computer do I need?
Optimally, you'd have a good power supply and a couple decent Radeon/ATI/AMD graphics cards. Because of litecoin's hash algorithm, the gap between mining with graphics cards and processors is less than with most other cryptocurrencies, meaning that mining with some desktop processors may be worth it after electricity costs. Note that mining with laptops is not recommended because of the heat generated by mining, and mining with NVIDIA graphics cards may not be worth the cost.
How do I know if litecoin mining will be profitable for me?
First, check how fast you'll be mining with your hardware, how many litecoins you'll mine in a day, and how much litecoins are worth. Now, multiply the number of litecoins per day by their worth. Then, find out the power draw of your hardware, and calculate energy cost. Then finish by subtract energy cost from your daily earnings. If your number is positive, you're making that much money per day. If negative, you're losing money.
Keep in mind that the worth of litecoins goes up/down, and you have to earn the cost of your hardware before you churn a profit. Mining difficulty also goes up/down, depending on how many people are mining how fast in relation to how many litecoins are supposed to be generated how fast. See the economics(coming soon) post for more info.
Okay, I did all that. How do I start?
All you have to do is download a program and change some settings (later in the guide), and you're ready to go. If you're comfortable with configurations and the command line, Reaper and cgminer are your best friends. Otherwise, GUIMiner-scrypt is right for you. If you want to mine on your processor, download the "batteries included" miner via this link and setup should be relatively self-explanatory.
Do I mine alone?
Due to the difficulty of mining, we recommend that you mine with a pool where multiple people mine together. Visit your pool's about or help page for proper miner settings, which we're about to get to in-depth!
Under the hood
Configuring your miner (aka the hard part)
Before we get started, you should become familiar with these terms:
None of those will have any affect on how fast you mine. The settings that we'll be focusing on are:
If you're using GUIMiner-scrypt, there are default settings for different cards (lower right dropdown). I'm mining on a 7870. Here is what it looks like for me. You can follow along with the rest of this guide to optimize your settings. GUIMiner-scrypt is just a GUI to cgminer and reaper anyways.
If you are using a command-line miner, like reaper and cgminer, I recommend you download and isntall Notepad++ or SublimeText if on Linux.
Reaper is currently considered to be the best tool for mining. After you unzip your downloaded file, in the folder you'll find reaper.conf. It should look something like this:
kernel reaper.cl save_binaries yes enable_graceful_shutdown no long_polling yes platform 0 device 0 #mine bitcoin mine litecoin #mine solidcoin 
This will make it mine litecoin on your first graphics card and reference litecoin.conf, which for me looks like
host us-pool.give-me-ltc.com port 8080 user poolusername.1 pass anything protocol litecoin worksize 256 vectors 1 aggression 18 threads_per_gpu 1 sharethreads 32 lookup_gap 2 gpu_thread_concurrency 15380 
As you see, my thread concurrency is slightly different from the default of GUIMiner-scrypt. I found that this concurrency gives me the best hashrate!
NOTE: I do not use cgminer to mine litecoin. If you plan on using cgminer, which offers more hardware-controlling settings, in the cgminer folder you will want to create a text file. Then, open that text file w/ Notepad++ or SublimeText, then Save As > cgminer.con > file type > all. This will save the file with the proper name and as the proper type. Note that cgminer does not support high concurrencies. For me, cgminer.conf would look something like:
{ "pools" : [ { "url" : "XXX", "user" : "XXX", "pass" : "XXX" } ], "auto-fan" : true, "gpu-engine" : "920", "gpu-fan" : "0-100", "gpu-memclock" : "1375", "gpu-powertune" : "20", "gpu-vddc" : "1.219", "temp-cutoff" : "85", "temp-overheat" : "80", "temp-target" : "75", "temp-hysteresis" : "3", "kernel" : "scrypt", "gputhreads" : "1", "thread_concurrency": "8192", "worksize": "256", "intensity" : "dynamic", "vectors" : "1" } 
You saw some settings similar to what we saw in Reaper's litecoin.conf. The other settings have to do with my card's clocks, voltage, and fan. This is covered in the overclocking section right below!
Overclocking (aka the risky part)
Okay, first off I'm not responsible if you cause damage to your parts. Please research safe overclock settings for your card. Second, don't be afraid. Modern hardware has many safety features in place that help prevent mayhem like me...lol jk this isn't a car insurance add. For your better understanding, become familiar with these terms:
No one setting controls how effectively you mine; what matters most when it comes to clocks is the ratio between your core/memory clocks. Generally, a ratio of 0.7 or below is best. You will need to experiment. If you're using cgminer, you can control card settings from the conf file. However, if you aren't, I recommend using MSI Afterburner as your overclocking tool. You will need to unlock some settings. Using my cgminer settings, MSI Afterburner looks like this. I have found these settings to be the most stable while bringing me a high hashrate.
Other people's optimum settings
You can check the sidebar for the hardware comparison chart, but it is rarely updated and has huge sways in results. It is a good starting place. The mods of this subreddit will be putting together an updated, more accurate list in the near future.

iwtwe's Total Noob Starting Guide. much noob..such help...very inform...wow

NOTE for seasoned miners, if I have made a mistake or if there is an easier way of configuring the miners or if I left something out, please do not hesitate to contact me about it so that I can edit this post accordingly. Let's help new people out so that the community will continue to grow! many thanks...wow
Hey you. Yes you with the eyes. Are you new to the world of crypto coin mining? Have no idea what a dogecoin is? Want to start mining dogecoins today and just can't seem to figure it out or get it to work?
Well have I got much help for you! About a week ago, I finally started mining after two painful days of trying to get it to work. Basically, I was a total noob and didn't really understand anything about mining in general. Because of the joy mining has brought me so far I am writing this guide to hopefully help out new members or other total noobs.
It's safe to say I've been bitten by the dogecoin bug. I started out with a measly 50 khash/sec and made approximately 10 coins in 12 hours. * My reaction when I finally got my miner to work * Reaction cont.
Now I'm up to 500 khash/sec after figuring out all the 'nuts and bolts' of mining. wow...such optimization...many hash
I'll break this guide down into three categories: Detailed Info, CGMiner Config for AMD Cards, and lastly, CUDAMiner for Nvidia cards.
Detailed Info very words....wow
A dogecoin is a type of crypto currency that is traded against bitcoins in a crypto currency marketplace.
You can earn dogecoins by contributing hashes (computing power) to a mining pool to help find a block.
There are a certain amount of dogecoins that will be released. These coins are released in the form of a block ranging in quantity of 1-1,000,000 doge coins. It is worth noting that the total quantity of coins per block will soon be halved to just 500,000.
Things you will need to mine: * dogecoin wallet * computer with a GPU * an account with a mining pool * a worker for the mining pool * mining software
1) [http://dogecoin.com](Download the doge coin wallet and install it)
2) Turn off your computer's anti-virus software and allow the dogecoin wallet through your fire wall. *VERY IMPORTANT
3) Run the dogecoin wallet and let it sync with the network. It is important to note that this can take a short amount of time or even up to 12 hours to complete. Just be patient. Use that time to research mining more.

Once your wallet has synced with the network, it is time to sign up with a mining pool. Think of a mining pool as a virtual supercomputer that is made up of many smaller computers connected together. This pool or 'super computer' allows for greater processing power. More processing power = greater chance of the pool finding a block.

Finding a pool
"Dear shibes!
Be careful when running Java and/or entering the usepass on sites. There are phishing sites out there that imitate other pools to steal your data.
When accessing a mining pool, DO NOT follow any redirects, always access the site directly and check the URL. For extra security, make sure you're using https://
Don't run Java!" <--- not my words, but very good warning to take into consideration
1) Perform a quick google search or use the links in the side bar to find a pool!
2) For this example I will be using https://fast-pool.com/index.php (I in no way, shape, or form endorse this particular pool. It was the first one I clicked. Feel free to use any pool you want, as the sites are all the same.)
3) You're going to want to click "Sign Up" in the menu on the left of the page. After clicking, sign up for an account.
4) After signing up for an account, log into your account. (For the sake of my example my mining pool site username will be "Shibe")
5) Now we will create a pool worker. Click "My Workers" in the menu on the left side of the page.
6) Choose a worker name and worker password and click submit. *NOTE THE WORKER NAME IS NOT THE SAME AS YOUR ACCOUNT USERNAME
7) For the sake of the example my workers name is "worker1" and the password is "x". *Note capitalization matters so don't forget it.
Now we will download a mining software and configure it to mine.
Before we do that I want to clarify what the info we will be using to configure our miner is.
1) Click "Getting Started"
In my example pool under getting started you will see this in "Step 3":
  1. Configure your miner.
    Settings for Stratum (recommended): STRATUM: stratum+tcp://fast-pool.com PORT: 3336 Username: Weblogin.Worker Password: Worker Password
If you use a command-line miner, type:
./cgminer --scrypt -o stratum+tcp://fast-pool.com:3336 -u Weblogin.Worker -p Worker password
The above explained:
Final Step Regarding Mining Pools
We need to add our payment address to our mining pool account so that we can receive the dogecoins we help mine.
1) Click "Edit Account" on the menu on the left side of the page.
2) Scroll down until you see "PAYMENT ADDRESS".
3) Minimize the webpage and go to your doge coin wallet.
4) In your dogecoin wallet click the "Much Receive" tab.
5) You will see the Label "Default" with an "Address" composed of a long random string of letters and numbers.
6) Right-click that string of random numbers and letters and select "copy address".
7) Maximize the pools webpage again and paste that address into "PAYMENT ADDRESS".
8) Enter you pin and click "Update Account".
WE'RE NOW READY TO DOWNLOAD A MINER such hooray....many celebrate
IF YOU HAVE AN AMD CARD, THIS SECTION IS FOR YOU!
*Note AMD cards are much better for mining than Nvidia. It's just the way it is!
We will be using cgminer to mine dogecoins with our AMD cards.
While there are newer versions of cgminer avaliable you're going to want to download cgminer version 3.7.2 because any higher versions do not support GPU mining.
1) Make sure your AMD drivers are up to date.
2) This version of cgminer is now only available on gitub at this url. The option to download the zip file in on the bottom left right side column.
3) After downloading the file, extract its contents to a folder on your desktop.
4) Before we do that go to Control Panel Folder Options View select "Show hidden files, folders, and drives" and click apply.
BEFORE YOU TRY THE BELOW, RUN THE APPLICATION AND INPUT THE SERVER URL:PORT (stratum+tcp://fast-pool.com:3336) "enter" USERNAME (Shibe.worker1) "enter" and PASSWORD (x) "enter".
*If the application runs without giving you errors hit the [S] and select "create config file" and hit enter.
5) If that didn't work, we will make a .conf file that allows cgminer to run correctly.
6) Now go to the folder you extracted cgminer into.
7) Right-click anywhere in the folder and select "New" Text document.
8) Right-click the new text document you just created and select "Edit".
9) Copy and paste the following into that new text document leaving no space at the top and enter the appropriate pool information accordingly. Noticed I used my STRATUM info from my example.
IF YOU HAVE ONLY ONE GPU USE THE BELOW
{ "pools" : [ { "url" : "stratum+tcp://fast-pool.com:3336", "user" : "Shibe.worker1", "pass" : "x" } ] , "intensity" : "10", "vectors" : "1", "worksize" : "256", "kernel" : "scrypt", "lookup-gap" : "0", "thread-concurrency" : "0", "shaders" : "0", "gpu-engine" : "0-0", "gpu-fan" : "0-0", "gpu-memclock" : "0", "gpu-memdiff" : "0", "gpu-powertune" : "0", "gpu-vddc" : "0.000", "temp-cutoff" : "95", "temp-overheat" : "0", "temp-target" : "0", "api-mcast-port" : "4028", "api-port" : "4028", "expiry" : "120", "gpu-dyninterval" : "7", "gpu-platform" : "0", "gpu-threads" : "1", "hotplug" : "5", "log" : "5", "no-pool-disable" : true, "queue" : "0", "scan-time" : "30", "scrypt" : true,
IF YOU HAVE TWO GPU's IN CROSSFIRE USE THE BELOW CODE
{ "pools" : [ { "url" : "stratum+tcp://fast-pool.com:3336", "user" : "Shibe.worker1", "pass" : "x" } ] , "intensity" : "10,10", "vectors" : "1,1", "worksize" : "256,256", "kernel" : "scrypt,scrypt", "lookup-gap" : "0,0", "thread-concurrency" : "0,0", "shaders" : "0,0", "gpu-engine" : "0-0,0-0", "gpu-fan" : "0-0,0-0", "gpu-memclock" : "0,0", "gpu-memdiff" : "0,0", "gpu-powertune" : "0,0", "gpu-vddc" : "0.000,0.000", "temp-cutoff" : "95,95", "temp-overheat" : "0,0", "temp-target" : "0,0", "api-mcast-port" : "4028", "api-port" : "4028", "expiry" : "120", "gpu-dyninterval" : "7", "gpu-platform" : "0", "gpu-threads" : "1", "hotplug" : "5", "log" : "5", "no-pool-disable" : true, "queue" : "0", "scan-time" : "30", "scrypt" : true, "temp-hysteresis" : "3", "shares" : "0", "kernel-path" : "/uslocal/bin" }
10) Click save-as Save as type, "All files" and rename the document to: cgminer.conf
11) Click save and run program.
12) If it still doesn't work try changing the intensity to a lower number or changing the workspace value to 64.
Everything should work now. If I have made any errors or if there are easier ways of doing this please let me know so that I can edit this. This is just what worked for me.
IF YOU HAVE A NVIDIA CARD THIS SECTION IS FOR YOU!
Before we do anything, go to Control Panel Folder Options View select "Show hidden files, folders, and drives" and click apply.
We will be using Cudaminer version 2013-07-13 https://mega.co.nz/#!hVREmSKA!VaGCdh3Ykfp-e8IOTFWaEXJGMa1JNVqPcdxawkCPRSE
1) Download Cudaminer version 2013-07-13 from that link and extract the contents to a folder on the desktop.
2) Open that folder and look for the Application.
3) When you've found the location of the Application it's-self you're going to right-click anywhere in the folder and select "New" Text document.
8) Right-click the new text document you just created and select "Edit".
9) Copy and paste this to the top line of the blank text document leaving no space in front and input the appropriate url, username and password from whatever pool you use. (I will be using my example pool info stated earlier in this post):
cudaminer.exe -o stratum+tcp://fast-pool.com:3336 -u Shibe.worker1 -p x
10) Click save-as Save as type, "All files" and rename the document to: Launch.bat
11) Click save.
12) Double click the Launch.bat file you just created to run the program.
13) Wait for the program to auto-tune your settings and then it will start mining automatically.
Everything should work now. If I have made any errors or if there are easier ways of doing this please let me know so that I can edit this. This is just what worked for me.

Dr Jally or: How I learned to stop worrying and love the ASIC.

I was a late comer to the bitcoin love, I started mining last summer, nothing major, have never had more than 600Mh/s to my name really... but on a whim I ordered a Jalapeno in late august, and then I tried to put it out of my mind as everyone else fought over if BFL would ever ship or not, etc.... I just figured that worst case, the money was gone really... lo and behold, it arrived about 3 weeks ago, let me briefly share a few things, as some of my tinkering and experiments may benefit others:
This past weekend I opened the little black box of mystery and had some fun:
I plugged everything back in, powered up my host... and noticed my jally was just flashing like crazy and my host couldn't see it. uh-oh. I powered it off, back on, and it was fine. Since then I've powered it off about 10-20 times, and twice it would go into "super fast flash like crazy but not work" mode. Simply unplugging and replugging would solve it. I have not dug into this at all, but I think it's failing to init or pass the boot up tests. There's word around town that you can tweak the firmware to push speed further or reduce the strictness of the tests it does, but I'm happy with what I've got, so I'm leaving it:
Right now
Other than to change coins or work on my host system (now that it's a raspberry pi I don't think I'll be changing it much more), it's been running non-stop at around that rate/temp since the weekend.
Right now my little rPi host is bashing away, with the jally and three block erupters (I know they'll most likely never reach ROI for themselves by themselves, I just wanted to tinker, but still may add a couple more to break 10Gh total just for bonus points), the jally firmware "upgrade" everyone talks about is really designed for one of the other models (the bigger ones), and that's why I think it reports as "BFL 0h" or "BFL 0d" I assume "d" and "h" are the two ASIC spots on the jally board that actually have chips on them in the jally...
I figure all in I'm looking at around... lets say $650 and 90 watts (max) total for ~8.29Gh/s... The erupters really distort my numbers right now, (without them it'd be more like $350 and 80 watts (max) for ~7.3Gh/s)... but again, hashrate is addictive.
The jally power supply has always seemed to run hot to me, even before I pushed the update firmware, so I may try and find a biggebetter quality PS for it, and more erupters will sadly mean I need a new usb hub, as my current one is only rated for 5v 2A, and it has to be close to that with 3 erupters, the pi, and the usb fan. :/ So I guess I've still got more investment to go, but it's just a hobby, I can quit anytime, right?
right?
tl;dr edition (or what I learned, without the story):

Mining experiences

I present to you my journey with Bitcoin mining.
About 2 or so years ago a somewhat-more-nerdy-than-me buddy of mine ropes me in to Bitcoins. I installed the client in a few places and let them CPU solo mine for a while. After a few weeks of nothing, I got bored and forgot about it.
Then in March this year, I jumped on the bandwagon again (all the while kicking myself for not sticking to it). This time, I figured out BAMT, played on deepbit for a while, learned enough linux to make p2pool run, and generally tweeked with configs in cgminer to make my GPU miners hum (and overheat).
Around April, I got suckered in by the BFL pitch and ordered a couple Jalepeno's. After "burning in" my stuff for a good 6 months, I guess they felt guilty and decided to ship them to me.
So now I've got these things hooked up to a laptop and the 10GH/s looks awesome after GPU minng (4 GPU's @ 750MH/s ea). The pool rewards tell a different story however (~.002/day). I've purchased a r-pi and plan to see how that'll play out with the ASIC's.
The GPU's have been re-tasked to LTC mining. We'll see how that goes.
I've come to the conclusion that while the steady and predictable payout of a BTC pool is smart, I'd like to play the lottery and just let my BFL's solo mine for a bit. I mean, how awesome would it be to check it one day and see the line "Found block for pool 0!".
Then again, the number of natural 20's I've rolled over the years is shockingly low. Still fun to dream. I imagine I'll return to the pool eventually with my head hung low mumbling "stupid blockchain"
TL;DR - mined bitcoins with different tech over time.

Setup Help

I have been mining DOGE with two R9 270s on BAMT but I want to try out multi mining. I'm assuming the only thing I need to change in my config file is the pool. Here's what I have:
{ "pools" : [ { "url" : "stratum+tcp://useast.wafflepool.com:3333", "user" : "my bitcoin adress", "pass" : "x" } ] , "intensity" : "19", "vectors" : "1", "worksize" : "256", "kernel" : "scrypt", "lookup-gap" : "2", "thread-concurrency" : "24000", "shaders" : "0", "api-port" : "4028", "expiry" : "120", "gpu-dyninterval" : "7", "gpu-platform" : "0", "gpu-threads" : "1", "gpu-engine" : "1150", "gpu-memclock" : "1500", "gpu-powertune" : "20", "log" : "5", "no-pool-disable" : true, "queue" : "1", "scan-time" : "30", "scrypt" : true, "shares" : "0", "no-submit-stale" : true, "kernel-path" : "/uslocal/bin", "auto-fan" : true, "auto-gpu" : true, "temp-target" : "70", "temp-cutoff" : "77", "temp-overheat" : "90" }
However, when I fire up sgminer, it freezes at "waiting for work to be available from pools" for a little bit and then just terminates. What am I doing wrong here?

Upgrading old Dell Studio XPS 9100 for modern gaming

Ok so about 5 Years ago my parents shelled out sub $2k to get me a Dell Studio XPS 9100. After a few years I began to experience some GPU problems and lost the original and a replacement to overheats. (One while mining bitcoin and the other while using dual monitors)
Since then, the computer has been sitting in the corner collecting dust. Now with a budget of $1000, I'm looking to try to upgrade this thing so I don't have to game on laptops and tablets anymore. Or at least, looking to see if it's worth upgrading or starting from scratch.
I've tried to look on PCPP for parts to give an example of what I'm working with, but I can't find any of the parts on there.
This is an Amazon link to the motherboard: http://www.amazon.com/Dell-Studio-Desktop-Motherboard-MIX58EX/dp/B008I5WOQM
Here are a few pictures of the machine, bonus cat included: imgur
(The video card is missing a capacitor, so It's just a token of remembrance now)
In essence, what I'm working with is:
My question is, should I even try to upgrade this rig a new video card (970?), maybe a new CPU if needed, and more RAM? Or should I say fuck it and try to go from scratch with a new case that I know will be standard?
And if I should just upgrade, any suggestions? I was thinking a 970 if possible or a 750Ti if not. But I'm just not sure what is actually supported with this mobo and what will cause problems.

Need help tweaking 7970s - stuck at 500-550 kh/s

I finally stopped being lazy and booted up my old 7970s that I used to mine Bitcoins. I am mining Tagcoins right now and I believe it will be up there along with LTC and BTC. It's only about a month old and is already at $1.7 and it's backed up by a multimillion dollar company. Read more here:
https://bitcointalk.org/index.php?topic=317408.0
Anyway a little history about these 7970s:
They were never overclocked.
They were always undervolted to 950 mv and memory underclocked to 100mhz
The temps were always below 70C with huge box fan blowing at them.
Current Settings for Scrypt Mining: undervolted to 1000 mv and stock settings for clock / mem at 925 mhz / 1375 mhz. These are Asus Reference cards (bought them at launch to mine BTC).
CGMiner Settings:
cd cgminer C:\Users\Bitcoin\Desktop\cgminer-3.7.2-windows\cgminer.exe --scrypt -o stratum+tcp://tagmining.com:3333 -u xxx.xxx-p password -o stratum+tcp://wk5.botpool.net:5933 -u xxx.xxx-p password -I 13 -g 2 -w 256 --thread-concurrency 8192 --shaders 2048 --temp-overheat 80 --gpu-engine 925 --gpu-memclock 1375
I am using the following drivers:
13.11 Beta Catalyst Drivers
2.9 SDK
CGMiner 3.7.2 (latest to support scrypt mining)
Computer Specs: i7 2600k 3.4Ghz Stock MSI Big Bang Marshall 3 8GB DDR3 RAM ASUS 7970 X 4 Reference Cards 1300W CoolerMaster Gold PSU 2TB HDD 7200RPM
Any help would be appreciated!
