How to fix CPU clock fluctuations in Silent Hill 2 Remake?
Walking through those eerie streets, the gameplay was smooth until these rhythmic hitches started popping up, which is a total mood killer when you're already on edge. The 3D V-Cache should be carrying this game, but my clocks were bouncing between 3.2GHz and 4.1GHz, sending frame times swinging wildly from 11ms to 24ms. I tried enabling Game Mode and killing every background app, but the stuttering persisted, and it felt like I was wasting the hardware's potential. I eventually dove into the BIOS, set PBO to Manual, and used Curve Optimizer to set a voltage offset of -20mV while forcing the minimum processor state to 95%. Monitoring through HWMonitor showed core temps stabilizing between 62-68℃, with clock variance squeezed to within ±50MHz. I actually bricked my session once with an aggressive undervolt that caused a black screen during save loading, so I had to dial it back to -15mV for real stability. Once that happened, L3 cache hit rates shot up and the input lag vanished. Performance analyzer data confirmed frame times finally locked in at 5.1-6.4ms.
