I've build a mining rig with 3 nvidia 1070 ti AERO and used a Asus Prime Z270-p motherboard.
I'm using nvOC and I've already enabled above 4G decoding and reset the security keys on the BIOS
Initially the system was booting fine, and i've set up the cards with CC 175 and a MC 1200, power limit of 115W and fan 80. On the 1bash
I've opened the miner terminal and it was mining around 480 sol's per card, with a temperature around 70 oC, i've letf it running for about 5hrs before turning off the monitor and going to work, at the time temperature were stable at 68oC with occasional spikes to 70oC.
According to the pool i was connected the rig was running for around 14hrs and just before turning off there was a spike in the sol's on the graph (nothing crazy). When i got home the RIG was on the bios. Now when i boot into linux if i leave the terminal open it crashes and reboots. If i close the terminal i can use the system, i can go into youtube and watch movies in 1080p, see the gpu's detected on the nvidia app with no arthiphacts.
If i try to run the mining terminal it crashes strait away, opening just the terminal without running the mining bash it also crashes but takes longer.
First of all, do you think it was possible to have burned the gpu's with those settings with around a total of 20hrs of work?
What can be causing this? I've already tried changing risers, formatting the USB and running it again, connecting the GPU one by one and all of them show the same behaviour
