So I clicked on the link in the OP to the Race Your PC thread, then clicked the link to my motherboards guide but it seems that site is down nowadays.
Anyone in here able to suggest a good overclocking guide for a Z68XP-UD3 motherboard?
Guide.

It's Z77, but it is similar for Z68. Do you have an aftermarket cooler?
It is as easy as putting the multiplier to say 43 for a 4.3ghz clock and the voltage to something until it is stable. 1.2 should be enough, but varies between chips.
