My i7-14700KF keeps dropping clock speeds during BioShock 4 combat, causing massive lag. Any fix?

It was a nightmare—my frame rate would suddenly plummet from 144 FPS down to 40 FPS in a heartbeat. In a fast-paced fight, that kind of stutter is basically a death sentence. Looking back at my voltage logs, the Intel Core i7-14700KF was hitting a 0.08V drop during peak transient loads, causing the core clocks to bounce erratically between 5.4GHz and 3.1GHz. I tried switching to the 'Ultimate Performance' power plan in Windows, but that's just a software band-aid that does nothing for hardware-level voltage instability. I had to go into the BIOS and change the Load-Line Calibration (LLC) to L3 mode and manually bump the Vcore offset by 0.06V. During an AIDA64 stress test, the cores stayed stable between 75℃ and 82℃, and the voltage swing narrowed down to +/- 0.01V. I actually overdid it once and pushed the voltage too high, which triggered a thermal shutdown—scary stuff—until I recalibrated my fan curves. Now the VRM area stays around 62℃ to 68℃, and that annoying coil whine has finally died down. System logs show the memory temps are holding steady at 58℃ to 63℃.
