Started building another rig today. Since graphics cards are so hard to get I've been ordering them where I can find them. I have 3 PNY 1070 Ti's on order and 3 EVGA 1080 Ti SC Blacks on order and finally 2 MSI 1070 Ti's on order. What has come in so far is the following:

1x - MSI Z270-A Pro
1x - Intel Celeron G3900
1x - EVGA 1080 Ti SC Black Edition
1x - Zotac GTX 1070 Ti AMP Extreme Edition
1x - Zotac GTX 1070 Ti AMP
1x - MSI GTX 1070 Ti Duke
1x - Titan 8 Case
8x - Explomos PCI Risers
2x - Explomos M.2 Adapters
4x - Corsair 120mm Fans

Some other misc stuff that I had laying around such as RAM, Power Supply, etc. I haven't installed all the fans yet and won't until the rest come in. So far I've only got the 4 cards going listed above. I haven't tweaked the configs much but it is hashing Zcash at 2260 Sol/s right now. Cards are limited to 150 watts for the 1070 Ti and 220 watts for the 1080 Ti...

Some issues I ran into... the fan in this power supply went out a while ago, so I had to order a replacement but the proper ones are impossible to find and they are a slightly odd size... so I had to connect it to the motherboard and that's the wire you see hanging out of it. The connector on the PSU board is some propietary crap I can't find. Also the screw holes on the Explomos risers doesn't match exactly the Titan 8 case... so I had to angle them slightly and can only get 2 screws in them. It works out and the cards are just slanted ever so slightly as you can tell in the pictures.

The Zotac's run a little bit slower than the cards in my other builds but that is to be expected. Overall with stuff being so hard to get and the price of these I think they are still a good buy. Feel free to ask any questions.

My config to control the cards overclock, power in ethOS and the local.conf are below:

Code:
fan rig6 60 90 80 80
mem rig6 4498 4498 4498 5400
cor  rig6 1940 1940 1940 1940
pwr rig6 150 150 150 220
Here's some of the results.. GPU0 is the regular Zotac, GPU1 is the AMP Extreme, GPU2 is the MSI and GPU3 is the EVGA 1080 Ti.

And total power of the cards...

Code:
# nvidia-smi -q -d POWER | grep Draw
        Power Draw                  : 148.33 W
        Power Draw                  : 151.68 W
