How to fix CPU frequency spikes on Colorful B450M-T M.2 V14?
While sneaking through overgrown streets, my frame rate would suddenly tank from 60 FPS down to 28 FPS, which completely killed the immersion. The VRM on the Colorful B450M-T M.2 V14 was struggling with the modern engine, with temperatures swinging between 85°C and 91°C, triggering an aggressive thermal throttling mechanism. I first tried enabling 'Ultimate Performance' in Windows, but that was a mistake; it didn't stabilize the clocks and actually bumped my idle temps up by 7°C. I eventually dove into the BIOS and manually locked PL1 and PL2 power limits to 105W, while disabling C-State deep sleep to cut down on wake-up latency. According to RTSS, my 1% lows jumped from 25 FPS to 42 FPS. It wasn't a smooth ride, though—my first attempt at bumping the voltage caused random BSODs during boot until I dialed the Vcore back to 1.20V. With the VRM now sitting between 78°C and 84°C, AIDA64 confirms the clocks are rock steady, and frame times are finally consistent at 5.1-6.4ms.
