Hey there, just a quick thought that’s been on my mind... I’m not a pro at overclocking, but the voltage I configured in BIOS doesn’t seem to align with what the system is actually using when under load. I set the Vcore to 1.295v for my 7700k to run at 4700 MHz, but if I lower it to 1.290v, I keep getting BSODs mainly during Firestrike combined tests. Even when the CPU is under heavy stress—whether on AIDA64, CPUz Bench, or gaming—I still see the voltage drop to around 1.224v. My question is, why does changing the voltage in BIOS cause instability if it’s stable under load? Also, my BCLK speed never locks at exactly 100MHz; it keeps fluctuating between 99.9 and 100.1 MHz. I found some links that might help: https://valid.x86.fr/nsii8q and https://www.3dmark.com/3dm/25962810, plus the Mobo page from Gigabyte. Thanks in advance!

BCLK tends to vary constantly. The drop in core voltage during loads is linked to your LLC (Load Line Calibration) configuration.

Snipergod87 :
BCLK always fluctuates.
The reason why the core voltage is dropping under loads is due to your LLC (Load Line Calibration) setting
Hmk, so if my system is stable as is, nothing to worry about then?

If its stable you don't have anything to worry about, if it wasn't stable I would suggest bumping the voltage or increasing the LLC setting
