> The CPU was overclocked from its default clockspeed of 4000MHz to 6531MHz without deactivating any cores or the Intel Hyper-Threading feature. The voltage was increased to 2.032V and the chip was chilled using LN2 cooling.

It's even more crazy that they managed to do this without disabling any of the cores. I wonder if the OS parked any of these cores. This blurb doesn't mention if they put the CPU under any load, or if the 6531MHz was achieved without load.

Also, liquid nitrogen? Is this common in the overclocking community now?

In the extreme-overclocking community yeah. (There are tournaments for this sort of thing afaik)

An AMD CPU broke 8GHz with liquid helium! http://hothardware.com/news/amd-breaks-frequency-record-with...

Yep. Liquid Nitrogen is the go-to coolant for overclocking records/competition.
