How To Build a 6 GPU Zcash Headless Mining Rig on Ubuntu 1. Using Claymore Block Operations. Latest version of my guide to building and operating a mining rig is here,  How to Build a 6 Rig GPU Miner for Zcash and Ethereum with Nvidia GTX 1. Ethos. Distro posted Oct 1, 2. Steemit. Bitcoin is getting all the press, and Bitcoin mining can be profitable. But the equipment is noisy, expensive, and hard to get. If you want to get started in crypto currency, and have a little bit of technical knowhow, I recommend you build a GPU mining rig first. GPU mining rigs are just as profitable as Bitcoin mining, the products are easy to purchase, and the GPU cards have a 2 year warranty in case you burn them out. They are multipurpose, and can be used to mine many different crypto currencies. These will usually pay for themselves in one year, including the cost of electricity. After that you are making money. Ive been building mining rigs using Ubuntu linux for a while now. I really like the AMD RX4. Ethereum miners to using Claymores mining code. I wanted to mine Zcash also, and found that the AMD R9 Fury cards were better than the AMD RX4. The first miners I built for Zcash used the Silent. Army miner for Ubuntu. It was good, but Claymores Windows version was 3 times as fast I moved the machines to Windows 1. Claymore miner. Fabulous performance, no problems. Except I dont like Windows 1. When I need to check on the miner, or reboot it, I want to be able to SSH to it directly, make the change, and be done. Windows was rebooting at inconvenient times for updates, and I hated having to VPN in and get a GUI going with No. Machine just to make a change. So when Claymore came out with a Linux version of the Zcash miner, I was very happy. I built a new 6 GPU mining rig and got things going. It works really well. Its set up to run headless on Ubuntu 1. LTS with the latest AMD drivers. Install Fonts On Ubuntu Server Setup' title='Install Fonts On Ubuntu Server Setup' />This same basic setup can be used to mine for Ethereum and Monero also.

First year mining pays for itself, then its making you money. Plug that into the Equihash numbers at Coinwarz, and youll see Zcash comes out pretty good. Bill of Materials.

Build Notes I used an MSI board in the video, and the Biostar on a different build. I like the Biostar better because it does not require any messing around with BIOS. It just works. And it costs less. Buy twice as many PCI E risers as you think you will need. Ive tried 3 different brands, and usually half of the risers will be bad and wont work. Most of the time the GPU card will stop working due to a bad risers after a few hours or a day. This latest batch had some that had electric shorts that prevented the PC from startingYou may want to buy two of the HP power supplies also. AMD RX4. 80 Option. As an option, you can buy AMD RX4.

I always forget something when I build the machine. Heres some basic instructions for the most efficient order of operations. The idea is to get a basic computer built, troubleshoot any potential issues, install the operating system and application, then build the rest of the machine. Hardware Build Part One. Assemble the Case. Put the CPU, CPU fan, and memory on the motherboard. Plug in the fan. Attach the ATX switches and LEDs to the power header. Plug the SATA cable into the motherboard. Put the motherboard in the case on the already attached rubber offsets. Attach the Antec power supply to the right side of the case. Use the screws that came in the box. Attach power cables from the Antec power supply to the Motherboard, CPU power, SSD. Attach the HP power supply and X5 board to the left side of the case. Use the bottom two fan screws from the HP power supply. Screw in one of the PCI X Riser cards, plug it into the PCI E slot closest to the processor, and plug in power from the power supply. Attach a keyboard, mouse, and HDMI monitor to the machine. Plug the power cord into the Antec power supply, turn on the power switch. Press the ATX power button. The machine should boot. If it doesnt boot, this is the time to do basic troubleshooting. Dont add any more graphics cards until later after the operating system is installed. The motherboard has a VGA connector if you want to connect a monitor directly to it. Just make sure there are no graphics cards plugged in if you use the onboard video. Software Installation and Configuration. Initial Operating System Setup. Install Ubuntu 1. Bitdefender All In One Keymaker. LTS Server. Do a standard install using all the defaults, include Open. SSH on installation. After install, login with your username and password. Get ip address with ifconfig. Go to your PC, ssh to the Ubuntu machine, and do the rest of the setup from your PC so you can copy and paste the commands. I prefer to SSH from Bash shell, but Putty is a good client also. Make things easier. Install some basicssudo apt update. Change colors in the VIM editor. If you dont like VIM, use nano instead. Add in new file. Improve the bash shellvim. In the file. bashrcchange forcecolorpromptyestoforcecolorpromptyesadd this at the end LSCOLORSLSCOLORS di0 3. LSCOLORSUpgrade the operating systems in a screen screen S upgrade. Fix the network so IP address can be changed from DHCPNot sure why Ubuntu locks one IP address into itself when it first gets an IP address. But it does. So that needs to be changed.
