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.

Can idle 3.05ghz @36 degrees c, so it's a nice little block.
and it is if you go check XS they dont even break 1.68v on these chips for LN2

My CPU will NOT stable under 1.34vcore (tested with prime).
With HT on, that's mean you adding 5-10 C.
Adding 0.1v to get from 4GHz HT Off -> 4.6GHz HT on is IMPRESSED. And look at the the WC setup, it's a super small rad.
The 4 GHz PII clocks on water are nice and it won't melt the hose :P
(and how many CPUs did they toss before reaching this one)
Now time to challenge it again.... but i just don understand why it is cooked, maybe because i did not set the voltage and let it be automatic. But high voltage should cook the CPU and not mainboard... :confused:
On water not the i7 965
intel dosnt want i5 to be clockable, they have been working on a way to allow i5 chips to FRY when you attempt to overclock them, It may not hit the market this time, but they have been working on it, at the very least, they will beable to tell if you took your chip beyond spec, have fun with RMA's on non-enthusist platform when u have overclocked it :(
Unfortunately Intel has been thinking about this for the better part of 2 years...they just can't find a way to implement it yet.
intels real plan is if they can empliment it that if you try and overclock the chip FRYS instatly, but in such a way that the system will tell you that you ruined your chip by overclocking and will have to buy a new cpu.
aint that a bitch? overclock ur system, fry the chip, endup buying another just so u can sell the POS and buy something else thats not so limmited haha.
keep in mind guys, im agreeing with you but it doesn't mean I can't bitch about it ;)
the downside is that they will loose their excuse about stab issues resulting from un-scruplus system builders overclocking systems(main excuse for this kinda move)
