So I'm trying to overclock my i5 2500k to 4.5 GHz but it will only allow me to set the CPU clock ratio between 16 and 37. Would this be because I'm missing something or would it be my motherboard limiting it, or something else?
Motherboard is a Gigabyte PH67-UD3-B3, BIOS is up to date. Was following this guide because I am clueless.
Cheers.
