how to OC my sandy bridge...?

post #1 of 10
Thread Starter 
first intel cpu that im using in my main rig/seriously OCing... what do i need to know? its a 2500K and im on a asrock p67 extreme6... what voltages are for what? like on my phenom II the cpu-nb was big for the IMC and the vcore was... well, the vcore. what is the PLL voltage? im very confused... i have overclocked many AMD cpus so i know the process i just dont know what all the voltages are in the BIOS/uefi

all help is appreciated

edit: so far 1.45v 5ghz just need to try and lower voltages and stabilize it

Well, PLL Voltage helps to gain stability with high overclocks. So you might have to bump it up a notch. I am coming off from a LGA775 setup myself and not very familiar with the i7 Sandy Bridge cpu's. But from what I hear Sandy Bridge requires very little or no skill to overclock, and from what I have seen around OCN I can say that you should be able to get that chip pushing 4.5GHz - 4.6 GHz easily. And with a bit luck, a good heatsink or water cooling and some skill, 5GHz is not impossible. Good Luck

edit: try looking through this guide, might be all you need to know - http://www.overclock.net/intel-cpus/...n-members.html

Increase multi
increase voltage
increase PLL
and your set.

That is why I LOVE older platforms as they take more to overclock. A lot more.

You do not increase pll on sandy bridge. It helps by lowering it. Overclocking sandy bridge correctly takes some time. Using offset overclocking is proving to be the best way. I helped someone understand it yesterday. Here' a link. Read through and you'll get the idea.
