Hello there, i have motherboard - ASUS Prime-P Z590 and wondering about one thing. When i set AVX offset 0 (which means i dont want change frequency for AVX instructions). Even then after setting it to 0, it still does underclocking from AVX instructions (tests of course).

I have every saving CPU things disabled and i dont know why this happens. I want OC, but also even in AVX stable. And when AVX kicks in, frequency went down. I have good temps i would say, in tests about 75c (OCCT, CineBench R20 for example). Actually i have 4.7GHz @ 1.3v without underclocking in AVX tests, whenever i raise frequency from 47 and up, automatically it drop down in tests do 47 / 46 multiplier, respectivelly frequency.

Can be this bug in bios? Or do i missing something?

Thank you for your help.
