Repeatable system freezes under GPU load with Threadripper & Ubuntu 18.04

Thanks for the suggestions guys. Here some more stuff I tried after scouring these forums:

  1. Set the BIOS according to VFIO BIOS settings for Zenith Extreme
  2. Also forced the BIOS to use PCIe Gen 3
  3. Set pcie_aspm=off in GRUB

It ran stable under load for around 24hrs before crashing again.

Currently using the latest BIOS. My memory kit isn’t listed on the QVL sheet, but there is a near identical 2666MHz kit listed, which is the speed I’m running at (I have 2 kits of 4x16GB 3200Mhz 16-18-18-36).

Right now I’m running memtester and will see if I can reproduce the issue with 1 stick of RAM. I’ll try the Pascal & Turing cards separately again, but when I tried a couple of weeks back it didn’t help

@Methylzero I’ll also try your stress test and report back

So many late nights wasted trying to figure out what is going on with this thing!
