Hi John, Thanks a lot for taking the time to look at this, even if it doesn't seem to be GPU related at first. > OK, that's a bit strange... I found mce log and MCE-Ryzen-Decoder as options for decoding. Sorry for omitting that information - indeed I was using MCE-Ryzen-Decoder, thanks for pointing to mcelog. The mce log output definitivly makes more sense, I'll try to experiment a bit with RAM. Thanks also for the link to the forum, seems of all the affected users, no one reported success in that thread. > For something as simple as the GPU bus interface not responding to an access > by the CPU I think you would get a different error (bus error) but not 100% sure about that. > > My first thought would be to see if your mobo BIOS has an option to force PCIE > gen3 instead of 4 and see if that makes a difference.

I'll give it a try and have a look at the pcie options - but as far as I know RX570 (polaris) should stay at PCI3 as far as I know. Disabling IOMMU didn't help as far as I recall.
