Intel Corp.’s next-generation code-named “Ivy Bridge” microprocessor is yet to be released, but performance enthusiasts have already managed not only to overclock the central processing unit, but managed to set a record: the unreleased chip was clocked at clock-speed that is two times higher than the default frequency.
According to Bright Side of News web-site, enthusiasts have managed to overclock quad-core Intel Core i7-3770K microprocessor from default 3.50GHz to whopping 7.063GHz. It is unclear what cooling system was used during the overclocking procedure, but the fact that an unreleased microprocessor can be overclocked by two times proves high potential of Ivy Bridge design.
The highest clock-speed ever achieved by a PC microprocessor is 8585MHz. Andre Yang has managed to ovcerclock an AMD FX microprocessor using Asus Crosshair V Formula mainboard and liquid nitrogen cooling system.
Ivy Bridge will generally inherit Sandy Bridge micro-architecture and will sport a rather significant number of improvements. Firstly, it will have certain improvements that will boost its performance in general applications by around 20% compared to Core i "Sandy Bridge" chips (e.g., enhanced AVX acceleration). Secondly, the forthcoming chip will have a new graphics core with DirectX 11 and OpenCL 1.1 support, 30% higher performance compared to the predecessor as well as new video processor and display controllers. Thirdly, Ivy Bridge will feature PCI Express 3.0 x16 interconnection as well as PCIe 2.0 x4 controller. In fourth, the processor will support a number of power management innovations. The CPU is made using 22nm process technology.

I highly doubt this was done on straight air, all i have to say is holy F%&^ if it was.
If it was cooled with nitrogen, you would think it would have beat the FX max oc of 8.5ghz and not be 1.5ghz behind considering it is at least a generation ahead in technology over the FX family lol

It's plausible it was done on peltier cooling. People have gotten 4.9 on Air using SB...So I imagine with cherry picked cpu's that 7 ghz might be possible "in the real world" with IB.
AMD also doesn't have a coldbug. Last I checked Intel still does. Not a big deal...AMD can have the record..Intel can have all the profits since their cpu's overclock way better on air/water.

I don't think there are many pelts around you'd want to deal with over 250watts (which the TDP of the chip over 7Ghz likely would exceed), and the heat generated on the hot side of a peltier that could handle this would be... frightening.
VERY roughly, add the heat generated by the processor AND the power used by the pelt itself + something around 30%... You get frightening numbers very quick. So a processor generating say... at a lowball: 250w heat + 300w pelt = 550w * 130% = 715w ? And what sucks is that is only maybe 50w of cooling power, so you're probably going to get beat by air cooling :/
Yes this is non-fact checked speculation coming out of my mouth, WHICH IS PROBABLY HORRIBLY INACCURATE. But there is a reason you don't see pelts so much after the Pentium III / Athlon Classic era.
Heat loads over 120w generally can't be sub-ambient cooled by pelts commonly available to overclockers.
Just had to add, if you want real nightmares look up peltier stacking... just wow! And sorry to keep rambling about this, I miss pelts - they were good fun back in my K6 days, but they are a handful to make work on anything that is an active heat load!
I always wondered if you had just a copper "cube" on top of a cpu, and slapped pelts on the remaining 5 faces if it would do any good. Probably not but it would be fun =D

If this isn't an exotically cooled 'suicide' over-clock and / or cherry picked processor sample then it's bloody impressive. I suspect it is either exotically cooled or cherry picked, but obviously I could be wrong. Either way it bodes well for over-clocking / under-volting on this architecture.

1.896V, definitely not for 24/7 operation and for sure not on air. We can't extrapolate real world overclocking on air at say 1.4V from that but it shows IVB has no problems scaling to 63x multiplier.
If IVB can do 5.7ghz+ on air, I'd be impressed. Early benches I've seen are showing 5.2-5.4 at reasonable 24/7 voltages on air.
