So this problem just occurred. I cannot set multiplier above 39 in BIOS nor XTU. Weirdest thing is that it was working earlier, couple weeks ago. I have been googling this but didn't yet find any solutions for my motherboard. Tried clearing CMOS but that didn't work. How do I fix this?

I have 3770k and AsRock z77 pro3.

Thanks in advance!

Update: Here is what I have tried: reflash, cmos jumper, battery, restore default settings, disable turbo in real temp
