Rig:
5x Zotac Amp Extreme 1070 ti
1x PNY Dual Fan 1070 ti
2x EVGA G2 Gold 750 using the Add2PSU adapter. One PSU powers 3 cards and all the risers. The other PSU powers 3 cards and the mobo/SSD
4gb Ballistix DDR4
Asus Z270-A
Intel Celeron CPU
120GB Adata SSD
Windows 10 64bit
Nicehash Miner
So I initially got this rig without the other 5 Zotac cards so I just set the motherboard on a box and used the single PNY card for a couple of weeks while I waited for the backordered Zotacs. Once I got a stable OC on the card, I ran the system without issue with the card plugged straight into the motherboard, no riser.
Last Thursday I got my other 5 cards so I fully assembled the rig. I got all the components in the frame and all the cards on the risers. Booted up fine and I got all 6 cards detected by doing the bios mods for this mobo that are on youtube. Everything looking good I thought.
I put a mild OC on the cards and started mining. About 12 hours later the machine was frozen, locked up. I rebooted and halved the mild OC to just +100 core and +200 mem. Started mining again, froze. Ok...so I did no overclocks at all, stock speeds. 80% power in MSI afterburner this whole time, FYI. Started mining again, froze up in just a few hours. What the heck? Then I tried one more time, stock speeds but this time 90% power instead of 80...although 80 should be just fine especially with no OC. Froze after 10 hours.
I don't get it. I'm pretty sure my motherboard and RAM are fine, considering the machine ran for a couple weeks with no issue when I just had the single PNY card. I have 6 extra risers for a new 1050 ti build I have coming this week, should I try swapping out the risers and see? Anything I'm overlooking here?
Its so frustrating to see your rig frozen up on your dashboard and you are helpless at work. Sigh
