How to calibrate power limits for Intel Core i7-14700KF?
This 14700KF is basically a space heater. During intense fights, power draw would spike to 280W, and the clock speeds would jump around like a heart monitor—it was ridiculous. My FPS was bouncing between 140 and 80, which made the game feel completely fragmented. I tried locking the CPU at 4.0GHz, but that tanked my overall performance by 30%, which felt like a total defeat. I eventually went into the BIOS, locked both PL1 and PL2 at 253W to force alignment, and disabled the Intel default 'extreme' overclocking profiles. HWInfo showed the core clocks stabilizing between 5.2-5.4GHz without those cliff-like drops. I did run into a brief BSOD during idle after the first power limit change, but a slight Vcore tweak to 1.28V sorted it out. The CPU now runs between 72-85℃, and the fans are screaming at 2200 RPM. I exported all the frequency and power mapping data to a log for future reference, and the tuning is now complete.
