How do I fix power limit throttling on the i7-14700KF?
During fast-paced city driving, my frame rate would suddenly plummet from 110 FPS down to 60 FPS, which absolutely killed the handling feel. The default power limits on the i7-14700KF are a joke for heavy physics calculations; my core temps were spiking between 98°C - 102°C, causing the clock speeds to jump erratically between 3.5GHz - 5.2GHz. I first tried enabling 'Ultimate Performance' in Windows, but that just pushed temps to the ceiling and triggered even harsher throttling—a total waste of time. I eventually dove into the BIOS, manually capped the PL1 at 253W, and set a core voltage offset of -0.050V. Monitoring via HWiNFO showed my load temps dropping from 101°C to a much more manageable 82°C - 88°C, and the frequency curve finally flattened out. I did hit a snag where the system rebooted twice during boot-up with -0.050V, so I had to dial it back to -0.030V for rock-solid stability. This shaved about 20W off the power draw and took the pressure off my cooler. After running Cinebench R23, I confirmed the multi-core clocks aren't tanking anymore, with frame times now sitting steady at 5.1ms - 6.4ms.
