How to stop i5-14600KF from throttling in Unknown 9?
While sneaking through dense areas, my frames would suddenly dive from 120 to 70, which makes precise movement feel clunky as hell. The default power limits on the i5-14600KF cause the clock speed to bounce between 3.8GHz - 4.2GHz under heavy load, leading to frame time spikes of 15-40ms. I first tried the 'Ultimate Performance' power plan in Windows, but the CPU hit 95℃ and throttled even harder—that was a wake-up call. I went into the BIOS, unlocked PL1 and PL2 to 253W, and set a core voltage offset of -0.05V. RTSS monitoring showed the frame time variance shrank from 12-40ms to a steady 8-12ms. I actually had two boot failures when I first tried the undervolt, so I had to back it off to -0.03V to get it stable. Temps now sit between 72℃ - 80℃. Cinebench R23 confirms the multi-core clocks are rock solid now.
