Very impressive. A Far cry from 5Ghz though. Call me stubborn, but I still don't think that's a sustainable speed. Even so, the near £200 E8600 at that 4.4Ghz speed is at most going to be 50-60% faster than the E4300 I had, far short of the 120% gains I've had with my Q6600 which cost two thirds of the price, for all the mediocrity it presented in overclocking.

but under water 5GHz is achievable.

Why are you so sure? I'd like to see some hard evidence of that. Prior to the arrival of the E8600, anything above 4Ghz was rare or unsustainable, 5Ghz is a vast leap from that, considering how blindingly easy it is to get any old chip to 3Ghz, even one that started at 1.6...

im sure if 4.5 is obtainable with air, esp with the week 22 E0 stepping (which i have once reserved for me now, from chilled PC's component seller K-Force) and he has been hitting over 4.5 on a TRUE.
even 4.7 would be nice, but 5 for personal satisfaction :D

1.47V though, on a 45nm chip, that hurts...

LOL which mod edited my post eh?
love the pic though :D
sam its mainly the CPU VTT and PLL which kill the 45nms moreso than the Vcore

well i guess i give up. i cant get it stable no matter what i try.
set it back to 3.7ghz and leave it alone. must not be ment for meto have any luck with this build. guess i need to go to AMD phenom and see what i can do.

No luck? You've got an extra 700mhz out of the CPU, which is far more than a Phenom will give you...

Silly high voltages, and watercooling, plus luck of the draw. My Q6600 can only make an extra 840mhz on a safe voltage, normally they make at least a gig no problem... I'm content though.

There is no chance that someone is running an E8600 stable at 4.5 and 5 GHz even with water cooling, in fact I don't think that a working stable system at 5 GHz is possible with Phase Change cooling. They clocked it, jammed it with as much voltage as they could muster, benched it, and then turn it down to prevent permanent damage to it. Note that none of the Benchmarks used lasted more than a few minutes. This is the kind of bull that RMA's are made of and newbies are left feeling inadequate because of.

I suspected as much, but I wasn't entirely sure. I know the E8600s are clocked higher to start with and have a good stepping, but Rob has got the sort of result I'd normally expect from an 8400, and the 8600s are only clocked 11% higher, so on a normal basis, while I'd expect to see 4ghz commonly from the 8600s, much higher than that and I'd start questioning the validity of the tests. 5Ghz I certainly think is beyond the reach of anyone on a daily basis.

The E8600 will hit 4 GHz easier with its higher multiplier, but as far as processors are concerned the E8400 and the E8600 are otherwise the exact same chip. That means that they both have relatively (not all chips are exact) the same ceiling. In the 2008 Tomshardware world overclock championships most teams maxed out at 5.4 and 5.6 GHz, but they weren't truly stable and the processors were chilled with liquid nitrogen. Most experts tend to agree that the maximum range for the Wolfdale core wit excellent cooling is about 4.2 GHz. Now if some members just want to try and see how far they can get it to snap a quick benchmark then I think that's great, but if they expect to keep it there and use it then I suspect disappointment won't be far behind.

right well then i hope to prove you all wrong, and as i have stated before i dont bench, i OC for my pleasure, if it fails, then its my loss not anyone elses, and i like to learn the hard way.
so long as i can get 4.7 24/7 use i will be content, but 5GHz is my aim.
to any newbie reading, please dont do what i do as you will not like the results when they turn bad. i am the Guinea-Pig, so just a warning to you lot. wait a month and a half, and let my chip die trying to get to 5GHz, not yours.

sam, i saw something worse then that when working at celestica. a sun microsystems' enterprise motherboard burnt right thru were the cpu was. there was a short between 2 pins in the cpu socket when the pins were spun gold fuss balls. this was back in 2000. couple grand was lost there.

Go for it! Clock it as high as you can get it. I still pop a few high overclocks every now and then, but once I'm done I turn it back down to be sensible and for stability. I always mention that it's probably not stable when I do it, but in the end I turn them all into work horses. Imagine doing a 16 hour encode and having it fail after 14 hours because of instability. When I encode Blu-Ray movies my CPU is at 98% to 100% all the way. In fact I might consider Blu-Ray encoding a new processor and memory stability test. That's also why I'm finally going to have to move to quad core.

Are you considering something like a 9650 soph? I would be interested to see what sort of speeds one of those could make 'genuinely stable' on water...
