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 Sad

Power limit decreases to 75%, then it will go well.
