Why is my Ryzen 9600x crashing with mild undervolting?
Asked by

Hey everyone, I recently built a PC and updated all my drivers and BIOS, then optimized things a bit. My setup runs pretty cool, with my CPU hitting a max of 85°C during stress tests. I've been exploring undervolting and was able to boot into Windows 11 without issues while testing various PBO settings down to -10. However, I've noticed that at -30 PBO, my system crashes about half the time when loading 3DMark or logging into Windows. This instability persists even when I adjust PBO settings up to -10, although everything runs fine at stock settings. I also undervolted my GPU and it runs stable, but the crashing rate remains. Why can't I run -10 PBO like most others seem to? Has anyone faced similar issues when undervolting their Ryzen 9600x?
Answers
It sounds like you're experiencing some instability due to how undervolting affects the voltage-frequency curve. Even though -10 PBO is considered safe by many, your chip might just not play along due to variation in silicon quality. You could try a method called curve shaping to add a bit of voltage in specific areas where it seems unstable, especially during lighter loads. And if you're still having issues, running at stock settings may not be such a bad idea to maintain stability.

Welcome to the world of the silicon lottery! Every CPU behaves differently, and even something as small as -10 can make a difference for specific chips. If you're curious, you could try bumping it up to -8 and decrease incrementally from there. It might help you find a sweet spot without the crashing!
