Issues with the system after BIOS update
Issues with the system after BIOS update
i have 6600k running rock solid on z170x-Gaming 5 @4.3ghz for over a year, never adjusted the vcore that was around 1.200 at load, and only minor changes on idle.
i updated to f22 bios, followed my usual OC settings, but got a blue screen when launching. now the default vcore shows 1.2 on bios, but in reality it's 1.164 at load—this isn't enough.
i manually set it to 1.25v and it displays 1.176 under load in cpu-z and aida64, and 1.236 on idle.
using prime 95 to test, i don’t like how the vcore behaves when I adjust it manually—it’s higher at idle than during load and doesn’t drop as expected. i’m unsure what I’m doing wrong.
is there a way to raise the vcore only during load and keep it lower at idle or even maintain the same level? any advice would be greatly appreciated.
I resolved it by understanding the new bios settings, and I’ll clarify this for those facing similar problems.
LLC to -high stops Vcore drops when loading.
Vcore to -normal then uses + and - to adjust or reduce voltage, which lowered Vcore significantly during idle.
Optimizing voltage to -yes helps stability, though the exact function isn’t clear.
Currently running 4.6 ghz with 1.308v to 1.340v, dropping to 0.888v on idle.
check for any new peripherals recently added and ensure they are compatible with F22 BIOS. if none found, go back to the previous BIOS and try to reestablish the working OC settings.
Configure the LLC (Load Line Calibration) to Level 4. This stops voltage drop during CPU load. Also, turn off power saving. If this doesn't work, go back to the previous BIOS version.

Optimizing voltage to -yes seems to improve stability.
