How to fix i5-14600KF power limit throttling in VR?
The default power limits on this CPU are a joke. In complex scenes, the clock speed would crash from 5.3GHz to 3.2GHz, creating a sickening tearing effect in VR. It felt like I was playing on a decade-old processor. I tried 'Ultimate Performance' mode in Windows, but the CPU hit 100℃ and triggered a hard shutdown—a reckless mistake that showed me my cooling was already maxed out. I went into the BIOS, bumped PL1 from 125W to 180W, locked PL2 at 210W, and applied a -0.05V offset to the Vcore. Using RTSS, my 1% lows jumped from 42 FPS to 78 FPS, with a tight variance of only 5-8 frames. I did get two BSODs during boot after the voltage tweak, so I had to back it off to -0.03V for total stability. Core temps now hover between 72-81℃ at 2100 RPM. Cinebench R23 loops confirm it is rock solid; config backed up.
