Confirmed using the gpu-z test thing the gpu runs at pcie3. 0 x16 as it should (as I'm on a riser), however I did notice when I had the 3070ti in the second slot, it was only running at pcie4.0 x4. Mobo manual says they're both x16 pcie4.0 slots.Is GPU being recognised at 16x or being capped at say 1x? That might explain the things you are seeing
I can't put the 3080 in the slot to test again it's too big (unless I take everything out of case).
You think issues I'm having would happen if both pcie slots were damaged from yanking out the 3080ti?
Because it WAS right after I put in the 3070ti, NOT right after updating bios and adding 5800x and during the 20-30hrs of gaming on the 3080ti that I noticed these issues to be honest. Otherwise I never would have even sold the 3080ti.
