Hey guys this is my attempt at OCing my i5 2500k to 4.5Ghz. Running 1.33v stable so far. LLC on at 75%
I did not turn off speedstepping or C1E or the other two C states yet if that matters.

I tried 1.30v, 1.31v, and 1.32v, but they all crashed within a few minutes of Prime95 Blend giving me WHEA Uncorrectable Hardware errors. How does it look?

Doing fine. Why don't you use offset?

Doing fine. You're using offset right? How's the temps?

I'm setting voltages manually, entering values directly as "1.3x" and also the multiplier as "45" in the appropriate fields.

Glad to hear I'm doing fine so far. Also forgot to mention my ambient temps are 80F (26.6C).
I was hoping I could get 1.30v stable but I guess I'm not lucky.
I was also thinking about getting a better CPU cooler than this Hyper 212. A Cryorig H5/7 or ID Cooling 240L.

EDIT: Oh why don't I use offset you ask? Well I don't know, I thought this is how you OC on my P8Z77-V.

Every mobo has offset and there is no sense in pumping full voltage at idle. You aren't going to be pushing much further and it's not even worth it.

True that. Since I have speedstepping on and all I should do that.
What offset would you say is equivalent to this 1.33v setting?

 

[k1114]

I don't remember the base value so couldn't say.

Yeah after doing some reading I would need to know the VID of the chip at this speed. HWMonitor says VID is 1.381 most of the time. Not sure if that's correct though. But if it was then I would probably set the offset to -0.05 or so.

 

[k1114]

Vid is the voltage the mobo gets and increasing vcore increases vid, or else the cpu can't get enough voltage. It can be different depending on llc. Different mobo manufacturers have a different starting point for offset, this is what I meant as base value. There is no standard and no way to know from your cpu. Starting close to 0 offset will get you an idea of what it is without worrying about too much or too less voltage. Chances are -.05 is going to be less then 1.3 at load.
