r/overclocking - for those who like to push their chips a little harder

I recently purchased a Ryzen 7600X3D. I’ve been testing PBO CO at -40. It survived over 2 hours of the AIDA64 stress test (CPU+FPU+Cache). I decided to try Prime95 Small FFTs and was disappointed when it crashed within seconds with all AVX extensions enabled. So I ran the same test with all the AVX extensions disabled - and so far it’s survived 45 minutes of the torture test (and counting, it’s still running). No clock stretching reported by HWInfo - effective clock is rock solid at 4.7GHz.

My question is - should I now reduce my CO negative offset until it no longer crashes with AVX enabled? I use my PC for gaming and web browsing/media consumption only. I have no idea how extensively AVX/AVX2/AVX-512 are utilised in modern games and basic desktop programs. Should I admit defeat and scale back my undervolting ambitions in the name of rock solid stability? I was getting excited when it seemed to pass the AIDA64 test, but now I’m not sure what to do.

Would appreciate the advice of more experienced overclockers. Also worth noting that this is my first experience with Ryzen, before this I had an i9-9900K, so I’m trying to familiarise myself with how Ryzen differs from what I’m used to.
