Just wondering if it is possible to o/c a notebook CPU, say a P8400.

It's not that I want to do it now, but maybe in the future......

PS - Good luck with the 5Ghz, let's see if you'll be able to stay at 5

Alright thanks,
I wasn't planning on doing it, I was just wondering if it was possible.

PS- When I called you guys crazy, I meant as in AWESOME not mental, I was complementing you people :P

Screw the case mods and work on cooling the processor directly with better than air cooling. Best bang for the buck is water! Although one does need to keep an eye on the faucet. LOL


A lot of good money can be spent on driving a lot of unneeded air.

Ray, according to Russ(theonejrs) I am mentally crazy. Or at least I used to be when I started overclocks with unstable high clocks.

On the electronmigration front, what sort of temperatures do you need for an E8600 to survive at 1.5V for more than a year? That's the sort of voltage I'm expecting to be necessary to run at 5Ghz and be stable in games, if not more.

Indeed not, but to stem the effect of electronmigration you can cool the chip down by a large amount, though in some cases I think that requires subzero cooling, which obviously water on its own can't offer.

Hmm, I thought that too initially, but many seem to suggest the effect is exacerbated by the extra heat generated using typical air cooling, and that WC's lower temps help reduce the effect.

Soph, I'm pretty sure he means a 120mmx3 fans radiator for water cooling.

Electromigration will occur naturally in any chip, but you are correct, water cooling slows it considerably, and probably enough for the chip to become obsolete before it finally goes down.

your water cool'd and have a AC case. isnt that combined a pretty big setup? i havent given h2o cooling a thought. but thinking of it to have a good h2o setup you need the external type cooling. dont that take up alot of space?

right seeing as i have never done the a/c before, soph, why s it better to have a bigger reseviour?

oh yeah soph, i am picking up a P5Q deluxe aswell, does the NB get too hot, or am okay without watercooling it?

But 5GHz at 1.5v? There I would have some serious doubts about it lasting a year. I see now where he is planning to slow it down some if he even reaches 5GHz, so it probably will last much longer with water cooling.

Russ

He'll be lucky to get a bench even at 4.5 GHz, but 4.2 Ghz with the right stuff is not out of the question. The E8600's are all EO stepping and are very overclockable with even lower Vcore than previous versions. I've just ordered a Q9650 which is also EO stepping and have been demonstrated to be good quad core overclockers. I'm not looking for any absurd speeds, but I do expect to at least match my Dual cores 3.816 Speed.
