_________________ UPDATED 3/20/2016 - qtminer install instructions for pool mining and GPU_SINGLE_ALLOC_PERCENT=100 for 2GB GPUs __________________ As the codebase developed, we now have a much simpler way to install and run a GPU miner for Ethereum.sudo apt-get -y update sudo apt-get -y upgrade -f sudo apt-get install fglrx-updates sudo amdconfig --adapter=all --initial 2) Reboot the machine.3) You should now be able to see all the video cards installed on your system using the command: aticonfig --list-adapters The item with the star (*) next to it is the default graphics output of the computer.In our case we have set this to the integrated graphics card and we will use the GPUs installed in the PICe slots only for mining.3) Trouble: If you're having trouble getting the system to display anything on the screen after boot, you are probably plugged into the wrong graphics card and you may have to change the defaults in BIOS as well as changing the default card the ubuntu uses for it's output.

You can force use of the integrated graphics card by entering the following at the terminal: sudo aticonfig --pxl-igpu Note: If you have a different wallet software like MIST, you don't need to install geth to mine with a pool (non-solo mining).1) Make a new directory for the latest version of geth mkdir go-eth135 2) Download the master branch for github /ethereum/go-ethereum cd go-ethereum 3) Enable OPENCL and Build export GO_OPENCL=true export GPU_MAX_ALLOC_PERCENT=100 export GPU_SINGLE_ALLOC_PERCENT=100 make geth 4) Make a new coinbase account (where your Ether will be deposited) build/bin/geth account new We use qt miner as are pool mining software.bitcoin kaufen via paypalSeveral mining pools use qt miner.bitcoin exchange sydney

tar zxvf qtminer.tgz cd ./qtminer chmod +x qtminer.sh 1) To start GPU Mining, go back to your go-eth directory 2) Mine with Multiple GPUs Where '0,1,2' means mine with GPUs zero, one and two.You should change this to list however many GPUs you have.Thus if you have only 2 GPUs and they are devices 2 and 4 you would type : '2,4' instead of '0,1,2'.To see which devices your GPUs are listed as use the command: aticonfig --list-adapters NOTE: All the rest of the commands are typed inside the go-ethereum console: 3) Ensure your rig is mining to your address web3.eth.coinbase (This should be set to the same address that you just created when you made your coinbase account) If this returns '0x0' that means you're mining rewards will get sent into a big black hole.diebold bitcoinFix this by typing the following inside the geth java scrypt console: web3.miner.setEtherbase(web3.eth.accounts[0]) 4) Check Profits This will return how much ether you have in your account 5) Check Hash Rate , they have several servers throughout the world: :4444 :4444 :4444 :4444 They use a PPLNS 1% fee system.ethereum hashing power

Below, you should replace the address with your own wallet address given to you by geth when you made your account.I mine with US East so to start mining I type the following: ./:4444 -u 0x8e61bf5a2e46d15774172781cf100ed0962cbb63.rig1 -G The command above will attempt to start all your video cards mining.In my case, this doesn't work because I have an AMD integrated graphics card as my first device (device '0' in the image below).2) Troubleshooting: If you have a an issue like me where you have an integrated graphics card, that you can't mine on, or you just want to specify the cards to mine on, modify the above qtminer command as follows: ./:4444 -u 0x8e61bf5a2e46d15774172781cf100ed0962cbb63.rig1 -G --opencl-device '1' This will start my first device.bitcoin via skrillTo start the rest of the non-integrated graphics mining I would then enter the following in separate terminals: ./:4444 -u 0x8e61bf5a2e46d15774172781cf100ed0962cbb63.rig2 -G --opencl-device '2' ./:4444 -u 0x8e61bf5a2e46d15774172781cf100ed0962cbb63.rig3 -G --opencl-device '3' If you have enjoyed this post, please consider sending me a beer!ethereum microsoft blockchain

Suffice it to say, I couldn’t keep my interest bottle in any longer and decided to get involved.Ethereum will eventually be moving to a “proof of stake”1 confirmation system.No one knows for sure when this switch will happen yet.Some speculate as early as this fall while others think early next year to be more likely.Essentially this means the community will be moving completely away from what we’ve known as traditional mining.Like ASICs, This will reduce all of our mining rigs to the status of useless—at least for Ethereum.Therefore if you’re thinking of getting into mining I’d recommend doing it quickly as your chances of making money are running out.I’m currently spending about $150 / month in electricity—$100 of that is the cost of the mining rig itself.You probably pay a different rate per kilowatt hour, but it’s important to do the math yourself to see how much overhead you’ll incur overtime.Remember to assume that you’ll be keeping it running 24 hours.

In total I spent about $2800 dollars including building materials for the case.As of this writing, I’ve made back $1,084 or 38% of the total cost of investment.At this rate I’m expecting to ROI sometime in September.I wanted my rig to be as future-proof as possible.Those in the Ethereum community know that as the DAG file2 increases, our GPUs will need to have the necessary RAM to cache it.Keeping this in mind I went with 8GB cards which is probably overkill, but I figured it would help in the resell value if I ever decided to liquidate.I also wanted to generate a decent hash rate which needed a higher-end card.Keeping that in mind, if I were to build a new rig right now I would probably go with something less expensive like an R9 370 to ROI more quickly.Hashrate: 155+ MH/s Revenue: $645.56 per month as of May 22th, 2016 I can’t give enough credit to the folks at gpuShack for creating ethOS.As a new miner, I didn’t want to spend hours of time setting up linux on a spare SSD potentially loosing precious mining time.

So I took a chance and purchased their mining software pre-installed on an SSD which they shipped to me.To give some background, ethOS is a linux based software specifically designed to mine Ethereum.It offers a lot of valuable tools like remote monitoring, remote configuration, and very useful analytics about your rig.I highly recommend them.(An example of what the remote control panel looks like within ethOS) I won’t be going into a step-by-step tutorial on how to construct the case itself.If you’re interesting in building a case like mine, head over to the BitsBeTrippin Youtube channel and follow their guide.I based my case heavily on their design and can attest to its durability and effectiveness.Here are the two videos in particular to checkout: /watch?v=Jnp9Ka8WVpA /watch?v=D5xNrlxsCVs However I would like to share my experience of creating the case to hopefully provide some guidance to newcomers out there.The materials I used are fairly straight forward.

Again, the dimensions and quantities can all be found in the videos listed above.You could construct the entire case using angled aluminum, but I found the wood was much easier to work with.Of course if it caught fire it would pose a higher risk so that’s something to keep in mind.One of the things that surprised me after I finished was how loud everything was.It wasn’t something I considered prior to building so in an attempt to reduce the noise, I put feet on the bottom with soft circle pads.This helped reduce the rattling quite significantly.Of course the main source of the noise comes from the fans on the graphic cards spinning at full speed, so be prepared for this.If you don’t want a lot of noise, look into water-cooled GPUs or do the opposite of me and keep your rig outside of your living room 🙂 I still believe Ethereum mining is profitable depending on the strategy you utilize.There’s many variables to keep in mind like electricity cost, building materials, Ethereum price, etc so make sure to do your homework.
