Hi, I have an update, I ran those tools and everything was fine. I have an old PC lying around so I decided to put my 3080 into it and test andddd. I get crashes on the system that worked fine before but with the 3080 in it. So, unfortunately i'm now 99% sure it's a GPU issue. Cyberpower also still won't seem to respond to me so I seem fresh out of luck. I'm using a gigabyte OC version of the card, so I want to try to underclock the card from its OC'd state and see if that promotes more stability; alas it seems that the MSI afterburner page just doesn't work anymore and i'm not sure how to go about messing with GPU clock speeds outside of it. I suppose the worst case scenario has come true.did we run these on it?
