Help me oc from 3.9GHz to 4.0! :)

post #1 of 44
Thread Starter 
As you can see, my e8400 is stable at 3.9GHz with 1.352v (9x multi).

What should I try to see if this chip will reach 4.0, or possibly go over?

Edit: I refuse to go over 1.3625 vcore as I hear that the chip's life is dramatically reduced if you go over that. And I mean dramatically.

I don't think you'll notice a big difference from 3900mhz to 4000mhz.

You're right, but I wasn't asking if I'll notice a difference.

Lol,
Try raising ur NB voltage?

I can't get it to exactly 1.3625v, but I was able to get it to exactly 1.360v. But it wasn't stable at 4.0GHz, so I lowered it back to 1.352v, according to cpu-z, and back down to 3.9GHz.

But as for being ok at 1.37v, I'm not so sure about that:

Here are some of the links:

Tricky Running 1.45v vcore: Oc/benchie: E8400 - Page 5 !!!

Tricky's chip no longer stable after 1.45v: E8400 Crapped out! YAY!!!!

Not only that, but this page on Intel.com seems to imply that the extreme limit is 1.3625v.

I'm not saying that ericoed is implying that one shouldn't go over 1.3625, but after seeing Intel's e8400 page, I'm not so sure about it yet.

I'd love to bump the voltage up to 1.37 just to see if it becomes stable, but I worry a lot about how sensitive this chip is said to be with voltages.

Oh, that's right, I forgot to mention that I had it at 1.5v, and it still didn't work.

Yeah, but the e8400 is far more sensitive to voltage than the robust q6600.

Bump up the nb and the memory v.
