I set a fixed vcore voltage of 1.28. Checking cpuz it shows 1.28 but as soon as I start up prime95 26.6, it shoots up to 1.344. My temps are under 70c on full load but am I setting the vcore wrong in the UEFI? Why is it not staying at 1.28? I have a ASRock Extreme4 Z170 board with the latest bios. Am I doing this wrong? How do I properly set vcore to stay at the voltage I want?
