I started my little OC journey by copying AncientGameplays Youtube recommended settings for 7900xtx. When i was just playing everything was fine but running a couple of programs and opening them on top of other crashed and rebooted the pc. Later i realised that earlier instead of the crash the picture would just go dark for a couple of seconds. It was annoying before but i didnt investigate it.
Now i know pretty much nothing about these things so i used Grok to solve it. First it adviced to check disable full screen optimization from these programs and on Steam it worked, no more crashes when opening steam on top. Then it it adviced to disable hardware acceleration on those that it didnt work and it did work on Mozilla firefox and Discord. Now on Surfshark i couldnt find an option to disable hw acc but weirdly enough the crash now only happens when i alt tab from a game and open surfshark and only when pressing notifications and updates. But im fine with that.
Next i Downloaded 3d mark timespy to check the OC vs non OC results and they were better as expected but when i ran the numbers through Grok it said my cpu score is about 30-40% lower than it should be. Next it adviced me to dowload cinebench and i got a score around 18000. After that Grok told me that the cinebenchmark is actually pretty good. Then we started to go down route of possible errors and checking them one by one. After many hours and multiple HWinfo logs we didnt find a solution for poor 3d mark score. So i asked advice on how to OC the cpu and the scores went up slightly, Timespy about 200 and cinebench around 300.
Now my question is does anyone have a clue why the Timespy score is so low and why did the blackouts and later crashes occur (Bios, Win11? I clean installed newest gpu drivers so i dont think its that). Im happy with the performance i see in games but it annoys me to think that is it possible im missing on 30% more cpu speed? Any advice would be appreciated.
Someone adviced me to use aida stress test to check what it says so i opened it and black screen crash again since i had multiple programs open. Maybe hw acceleration again since it was the first time i used it. I rebooted and run it with stock GPU OC with no problems. Result pictures attached with timespy results. The exact cinebench r23 score was 18383
