" rel="nofollow - Anyone else has issues with latest bios (P1.80) that cpu cache ratio stays at default 44x/4400mhz no matter what you set on uefi? I just tried to set cache multiplier to 46, according uefi main screen cache is set at 4600mhz, but on windwos accoring  hwinfo, cpu-z and other programs cache is still running at 4400mhz.

Edit: Hmm, i can set it lower than 44, example just tried 42 and it worked fine. But on some reason it wont go above 4400mhz no matter if i set multi to 45.46.47, it just remain at 44.

i7 8700K. As i said uefi main page says says the changes to the cache ratio has taken effect when i adjust it, but on OS it has reverted back to 44x/4400mhz.
