Hey guys...today i upgraded my windows 7 to windows 8..noticed cpu running at stock speed...so i went to bios to overclock again...aand noticed i cant change core multiplier...whatever i write after pressing enter or moving it returns to 38...updated bios back to 1.3 1.2 then again to 1.4 and all the same...last time i had same issues with windows 7 and bios 1.0..so i just upgraded to 1.40 and it worked...also tried removing cmos battery... Any suggestions guys? Or its just bad motherboard?
More aboutproblems locked multiplier
Forgot to mention..i5 3570k and asrock z77 extreme4-m
this may sound stupid, but instead of hitting enter after inputting a desired number in the bios, try hitting F10.
