I’ve been trying to get a stable overclock on my Ryzen 5 7600X, but no matter how carefully I adjust the voltage and multipliers, my system becomes unstable during longer gaming sessions. I’m wondering if my approach to PBO curve optimization is just off, or if I’m missing something about the new architecture.

I tried chasing stability with longer gaming sessions and kept hitting a wall. The clock would jump during load and then settle into a strange jitter, and once the game froze even though the temps looked fine. I ended up pulling back on the memory timing and hoping that would help.

I fiddled with PBO curve optimization and it felt like guesswork; there was barely any noticeable difference and it would drift session to session.

I learned that the power plan and thermals can matter more than the OC knobs. I watched temps stay near boost ceilings, so I backed off voltages a notch and saw more consistent behavior.

The BIOS side was annoying too; LLC levels and how the VRM behaved on long runs made a bigger difference than I expected. A hotter VRM frame and a louder fan curve would nudge instability back in.

Could it be something else like the game engine or GPU drivers instead of the CPU, given the same OC setup?

I tried turning PBO off entirely and running stock; it was noticeably more stable but obviously not as fast. I guess that was the trade-off I couldn't justify.

I gave up on a perfect stable overclock and just used a modest profile for steady frame rates; maybe the real problem is that the whole approach is chasing a moving target with this silicon.
