Intel Core i7 Makes it Past 4.61 GHz with Water-Cooling
In a move that asserts Intel's undisputed leadership over the PC microprocessor market, Intel senior performance analyst François Piednoel conducted a special exhibition at the CES 2009 event, where he demonstrated the Core i7's overclocking and resulting performance potential employing water cooling. The water-cooled Intel Core i7 reached speeds in excess of 4.60 GHz, proving it has better overclocking potential than AMD's Phenom II X4 when water-cooled.
The setup included an Intel Core i7 sample seated on an Intel "Smackover" DX58SO motherboard. The motherboard was backed by Intel's own desktop control-center software that provides software-level performance management and monitoring. The processor's vCore was set at 1.44V, with the northbridge set at 1.21V. The clock speed of 4.61 GHz was achieved with a bus speed of 144 MHz with a multiplier value of 32x. Temperatures recoded showed the CPU chugging along at 61 °C, with the CPU VRM at 31 °C and the X58 chipset at 41 °C. The feat shows Core i7 to be the better CPU to overclock when water-cooling is used, while an Intel Core i7 is yet to reach 6.2+ GHz speeds, just for the kicks.

So, on water, Phenom II vs Core i7, and....
Well, you know what I mean.
LN2, dry ice ect is just for record breaking and that cannot be run 24/7 anyway
i want to see straight i7 vs phenom II on air reviews if anyone knows of any id like to see them
me im waiting for i5 which is supposed to be the mainstream cpu line
also, is that new intel software only i5/7 or will we see a version for 775 chips?
Ummm what the heck does that mean. Seriously some of those guys at fudzilla should take some english classes.
i don't see the point of all this i7 better than p2;p2 is made to be a c2 alternative and has his position there; maybe the next amd cpu will take the fight but honestly i don't see why ...
who don't like amd buy intel and viceversa, but we all must thanks amd for the competition and the fight they have (david vs goliat) and prey they remain in business otherwise bye-bye good prices
We all know that prices will drop... eventually. I'm currently putting together a WC setup that will still have my old E6600 in it, and eventually an i7, but who knows when.
Thing about this article though, it says it was using the desktop control centre thing, so overclocking was done within Windows, but could it actually POST at that speed? If not IMO, this is not impressive.
What a great idea, now someone run F@H or soemthign on it, and burn it out. Intel doens't have much to be scared of other than the voltage intolerance of their new chip, it is highly possible they are still searching for the perfect chip to get to 6Ghz with. Either way, AMD has made a hell of a chip that overclocks better than the competition for less.
anyone want to see if a ES 945 can break 4.6ghz on H2O?
bet if i get there it runs cooler too
and its really not that low of voltage on this chip maybe on a C2Q but not a i7
Low multi + High Baseclock is alot cooler than low baseclock + high multiplier.
Consider, the Core i7 now has the triple memory controller DDR3 on chip, and 45nm same as the old Quad, I don't think 1.44v is high.
