You guys are old news:

my E8600 does over 5ghz easy on air.. There's air cooling and then there's air cooling. Mine was done in about 8-10 celsius air temps, imagine some of the air clocks when the northern hemisphere winter comes.

but dam that is awesome low voltage for those clocks! >4.9ghz with 1.464v... that chip is a gem

I don't think that perkam would close or move his own thread

I was just mentioning that earlier, it really depends on the ambient temps, of course, but he says here that his ambient temp is 20C, I mean that sounds unbelievable, but he's showing a pic of his setup there. I believe him and he really has a miraculous system...

I should clarify I guess. I'm not doubting the clocking for a second. I just think a 4.9ghz 3D air clock will be a lot more common once more E0 chips get into circulation, and once the northern winter sets in.

Whats far more impressive is the voltage required for those clocks. If he pushed it a bit more then waaaay over 5ghz should be doable.

For the record here's a couple of my attempts with cold air (For Australia that is haha)

5050mhz 32m @ 1.575vcore

and an Aquamark @ 5049 @ 1.53vcore

I don't mean to thread crap, SPL's is a superb overclock, but the low voltage is the really impressive part.

well, are you sure that his chip will react on more volts as you would expect it to react? I'm pretty sure that he would have tried it already, upping the volts. Maybe the temps are keeping him from upping the volts, I don't know...

Yeah i'd say there's some headroom left, most 45nm chips should scale a bit further with a bit more vcore, perhaps he has tried, I don't know either.
