New PC - Low GPU utilization+fps issues - 6900 XT defective? - How to troubleshoot?
Description of Original Problem: Noticed that fps would tank drastically after some daily use on pc. In certain games where I normally expect high fps would be cut down by more than half during this my issue. GPU utilization would drop from 80-90%'s to 50-60%'s with obvious fps decrease. Some games are still playable while others become unplayable due to stutters and severely low fps (165fps->60fps). Restarting the PC would generally resolve the issue until it occurs again.
Timing is intermittent, haven't been able to reliably reproduce/trigger issue on demand.
See example in borderlands 3, where in the same scene of benchmark I would receive 250~fps compared to 160~fps when issue occurs. GPU utilization when 250fps is around 80-90's while 160fps is closer to 40-60's.
Using adrenalin stress testing, I have image of when GPU is working as expected and when it's a "problem". I noticed that during the "problem" stage, clock speeds and power consumption flutuates and spikes sporadically. See images for reference.
I have monitored CPU during these times and while CPU usage is around 40%, none of the cores reach 100%, so I think it is not a cpu bound situation that is causing lower usage in GPU. I could be wrong, I am not exactly super tech savvy.
My question is "How should I go about continuing to troubleshooting this issue? & How can I determine if there is something wrong on the hardware side AKA defective?"
Troubleshooting: Things I have tried: -Set minimum clock to 100MHz below the max clock speed in adrenalin (clock speeds go up but usage still remain low) -Disable Deep Sleep States using MPT -DDU in safemode and reinstall chipset and GPU drivers -Tried adrenalin versions 22.5.1 and 22.11.2 (Issue occurs in both versions) -Using different power plans on PC between balanced and high-performance -Disable Ultra Low Power State (ULPS) in registry -Disable TPM and fTPM in bios -Turning off CPU overclock and running in ECO mode -Resetting PC using Windows -Reinstalling Windows via Media Creation Tool USB
