6 GPU Nvidia 1070 Mining Rig Build

Today I present to you the latest in the rig family, the 6 GPU 1070 mining rig. As usual, we have a cheap, efficient and portable rig rack. I’m sure this will interest many people due to the fact that AMD GPU’s are now quite expensive and still hard to find. People are buying millions of them. Millions. When history repeats itself (and it will), I will be buying them off ebay for insanely cheap prices. Nvidia high end cards, on the other hand, can mine multiple algos much better and will most likely have a better resale value. Moving on !

In this system we have the following components (or similar, buy what is on sale for decent price/quality) :

Skylake CPU (example) :  Intel G3900
Z170-E ASUS 6 GPU motherboard (go with what is available)
DDR4 RAM : Corsair 2x4GB
USB Risers : There are many models, with 6-Pin, SATA and molex connectors.
SSD : Sandisk 120gb
PSU : EVGA 1000GQ
EVGA 1070, consider what is available at the best price.  1080/1080ti can work also but you may not be able to have 6.

Win10 works well (enable win10 mode in bios, install, then turn off), remember to disable all the nonsense and updates and to create a power profile that doesnt turn your stuff off.  For other software you can get MSI afterburner, EWBF for ZCash, ccminer/excavator by nicehash or other for different algos.

Building an Nvidia rig is so much simpler and easier.  The overall system is much more stable too.  There is literally nothing else to do.  Your GPU’s should be detected, if you set PCIE to gen1 and above 4g enabled in the bios (if available).  There may be other options depending on your motherboard.  Here are some results for the most profitable algorithms (power usage is for overall system, from the wall with wattmeter) :

ZCash (380 to 435 sol/s).  Mem -502, core +135.
    65% tdp : 700w
    75% tdp: 800w
    90% tdp: 950w
ETH (27 to 30mhs).  Mem +395, core -150.
    65% tdp : 700w
    80% tdp : 835w
    90% tdp : 920w
LBRY (260 to 290mhs).  Mem -502, core +135.
    75% tdp: 805w
    90% tdp: 910w
DGB-Skein (500mhs).  Mem -502, core +135.
    65% tdp: 700w
    75% tdp : 800w
    90% tdp : 940w

I'm sure you can see a pattern here for tdp.  The way it works is simple:  lower tdp lowers core clock, therefore power usage.  Play around with the core setting to find a sweet spot.  In each tdp setting, the real core clock is actually different.

You results may vary depending on core and memory clocks.  It is more efficient to run at a lower TDP.

If you have miner specific questions, it is best to go to the bitcointalk thread and read up on it there, and ask your question there.  Other than that, i’ll be happy to help, happy mining !
