Linux Litecoin Mining Rig Hardware Kit List 3

My plan was to build a mining rig that would run on Linux and would need to have the ability to run two high spec AMD GPU’s to get a hash rate of at least 1000kh/s for Litecoin Mining.

This is the Kit List that I ended up with for my Litecoin Mining Rig:

2 x Sapphire AMD HD7950 Flex OC Graphics Card – 3GB (GPU’s) -  HD7950′s are good for mining as they are relatively low power consumption but high hash rate

Cool Master RC-902XB-KKN1 HAF XB CASE – This is an awesome case. It has plenty of room for the GPU’s and has plenty of air cooling

Sandisk 64GB SSD – Solid State Drive – SDSSDP-064G-G25 – A fast SSD 64Gb hard disk that is plenty of space for the OS

CORSAIR 850W CMPSU-850AXUK - A top end PSU that will easily power both GPU’s with spare wattage left over. Modular design means tidier cables

16GB (2x8GB) Corsair DDR3 Vengeance, PC3-12800 (1600),Non-ECC Unbuffered - 16Gb Memory (overkill but I may use one stick when I build a 2nd mining rig)

AMD Sempron 190 Dual Core Processor - Low wattage CPU ( Only 45 watts )

MSI 990FXA-GD65 AMD 990FX MoBo - Motherboard that will support 2 x PCI-e 16 Cards

Noctua NH-U9B SE2 Dual Fan – Fan to cool down CPU. Better than stock CPU fan with quieter fan.

Arctic Silver5 THERMAL PASTE – For application to CPU

ScanFX TIM Cleaner – For CPU in case I need to re-apply thermal paste

2 x FDesign FD-FAN-SSR2-120 120 R2 – Quiet Fans for PC case to replace stock fans

200mm CMaster MegaFlow BlueLED – Quiet Fan for PC case. Case does not include 200mm fan.

Energy Plug Meter – To measure wattage that Mining Rig is drawing from the mains. This allows me to work out energy costs so I can project profits.

 

Building the Rig

When the components arrived I was happy I had opted for the HAF XB Case. The GPU cards are very large and this case allows airflow over the top of the cards. I won’t run through how I fitted the components together as I will assume that most people building their own mining rig will have knowledge of building PC’s.

After the Rig was built I took a reading of the wattage using my Energy Plug Meter to understand how much my power costs were going to be. The max wattage was 600 watts according to my power meter. The wattage tended to jump around from 500-600 watts but this meter also has a setting to show your maximum usage in watts so I will be using 600 watts for calculating my power usage costs.

Software

Operating System

I decided that since I run Linux as standard on my home pc’s that I would like to have linux as my OS for my mining rig. After researching online I decided that Xubuntu would be the best OS for my requirements. This is a slim version of Ubuntu. I installed this using a USB key as I didn’t want to buy a CDROM drive for the server. All you need to do is use a different PC to drop the Ubuntu Image on to the USB stick. I used a program called UNetbootin to do this.

You can download it for free here http://unetbootin.sourceforge.net/

Mining Software

After carrying out some research I found that the most reliable software for mining currently for Ubuntu is called CGMiner

You can download the latest version for Linux here

AMD Graphics Card Drivers for Linux

I found that Linux drivers were available for my HD 7950 here

You also need to install the AMD SDK with OPENCL support for Linux. You can download a copy here

 

Here are some photos of the finished Mining Rig:

I will write up the step by step method for configuring Linux and installing the above software in my next post. This post is just to summarize the specification for my mining rig. I can confirm that this custom mining rig is currently hashing at over 1000Kh/ps with some overclocking.
