Anyone have step by step instructions on how to OC this bad boy?

I go in the OC Tweaker in the UEFI setup and I can see the max core limit set at 33 (3.3ghz). If i raise that to 40, will that be all thats necessary to get me to 4.0ghz?

thanks

i have asrock extreme 3 motherboard and under tweaking/oc tab in bios it has pre set configurations going from 4.0 ghz turbo (my stock turbo is 3.5 in 2550k i think) all the way up to 4.8 ghz turbo. if you want to go hiher you have to apply the overlock settings yourself.

Is that the first selection called LOAD OPTIMIZED OC SETTING? i just select say 4.0 and save and exit? no changes to voltage or it does it automatically?

So i selected 4.0 and saved. but when it loads up, everything shows 3.3ghz still, coretemp, speedfan, my computer properties... did i do something wrong?

I would just suggest not using the default OC profiles and to just OC manually. That way, you know exactly what your getting.

if you want fallow the guide and you will see it will show your ghz

I tried to follow that guide but i think its a little out of my league... i understand adjusting the voltage and multiplier, but when i get into the bios there are so many choices, at least 8 different items in the voltage control section alone. a preset seems more my speed...

I have that same model board (P67 though) with an i7 2600K. I have multiplier set to 46, PLL voltage at 1.75, Short and long term duration power limit @ 200 watts, core current limit 200

And Offset voltage @ +0.040 (1.32v). Even if you offset to -0.005, you should be able to do 4.0-4.3 (if not higher) with no problem
