Can PBO Curve Optimizer fix voltage instability on Biostar B650MT?
The power delivery on this board is a complete mess; the voltage bounces between 1.1V and 1.3V like it's on a trampoline, which just confuses the CPU. During extreme weather simulations, my frame times would jump from 16ms to 55ms, causing these sickening micro-stutters. I tried locking the CPU frequency at 3.6GHz, but that killed my overall performance by 30%, which was a joke of a solution. Instead, I used Curve Optimizer to set a -20 offset across all cores and shifted the VRM fan curve to kick in earlier at 60℃. Checking RTSS, the frame time variance shrank from 16-55ms to a steady 12-18ms, making the driving experience actually feel smooth. I did run into a few random BSODs at idle right after the tweak, so I backed the offset off to -15 to stabilize it. CPU temps are fluctuating between 65-78℃ with fans at 1800 RPM. Exported the load logs and the voltage is finally under control.
