I maintain a consistent 4.7GHz overclock on my i7 6700K. During regular tasks like browsing, the speed remains stable around 4.65Ghz. However, during stress tests or games such as Battlefield V, performance drops significantly to about 4.3Ghz, often fluctuating between 3.7Ghz and 4.0Ghz. Once I stop whatever I'm doing, the frequency quickly returns to 4.65Ghz. I've reset the battery BIOS, adjusted power settings, disabled Intel C-State in BIOS, and set minimum CPU usage to 100% in Windows Power Management. I've also turned off all power-saving features on my MSI Z170-A. My readings are normal, but I'm still struggling to identify a fix. I haven't found any solutions online yet.

This doesn't impact how I function. The CPU is operating as intended.

Check the power settings and try turning them off in the BIOS.

I was looking for improved frame stability in Battlefield V, as it struggles to maintain performance above 4Ghz in that title.

Setting 999W to maximum power worked perfectly. In Task Manager I notice 4.69Ghz and it’s stable.
