These should help you out:

P67 Sandy Bridge Overclocking Guide For Beginners ASUS Mobo

The ULTIMATE Sandy Bridge OC Guide (Gigabyte Mobo - Awesome thread, special thanks to sin)

Official ASUS P8P67 Series Overclocking Guide and Information JJ @ ASUS

P67/Z68 BIOS Guide - BASIC~Intermediate Overclocking Raja @ ASUS

MSI P67 Overclocking Guide Great Read for MSI users.


Whatever these guides say, leave C1E,Speedstep on Enabled run C3 and C6 Report on Auto (disable if your using Offset voltage) and also leave Spread spectrum on.

Also LLC on ultra high is usually the best one, make sure VRM frequency is on 350 for best stability, Duty and Phase control on Extreme and CPU current capability on 140%, other than that, the only things you need to change is the vcore, vccio, pll voltage and dram settings (timings and voltage)

Hope that helps

I added the right bios and no worries. You have a twin bios in case something like that happens

2500k's generally get past 4.5ghz with decent cooling, for a 24/7 overclock i'd thoroughly recommend 4-4.5ghz though

as a quick and dirty overclock i'd do what ecnelitsep says, 40 multiplier and vcore 1.2v, run prime95 for a few hours and if you're good you can start to tweak it more / up the multiplier,

if you bsod at any point or error out in prime, you probably don't have enough vcore, in which case bump it up 2 notches and try again until you remain stable for a few hours,

use manual voltage for now, until you get a feel for what your chip is capable of, then you can use offset to get the advantages of energy savings
