Question Gigabyte Motherboard oc?

[xtremexyz]

Hello, I have a Gigabyte B75 motherboard with a i5-2500k CPU, in the BIOS settings, it only lets me increase the CPU ratio to 34, as far as I know the i5-2500K is overclockable, is there a fix to this?

Should just increase the multiplier.
Do you have latest BIOS?
