AMD's Upcoming Phenom II X2 555 BE Overclocked to 6.6GHz

Complete with Youtube video of the feat, which was made possible with the help of some liquid nitrogen(LN2). 6.6GHz, unlocked to quad-core.

The AMD Phenom II X2 555 Black Edition is the successor to the well known Phenom II X2 550, which has made its rounds through the online media a while ago, due to the ability that some samples have of being unlocked to a full Phenom II X4.

This new X2 555 model is available in the AM3 form factor - which also works in AM2+ compatible motherboards - and has a clock of 3.2GHz, 6MiB of L2 cache and an HT link @ 4 GHz. Being a Black Edition CPU, it comes with no cooling fan and an unlocked multiplier.

This overclock was achieved on a Biostar TA785GE 128M motherboard, full with the unlocking to a Phenom II X4.
Biostar has been building some of the best overclocking motherboards out there and the rumor mill whispers that this is because the legendary Oskar Wu has moved there when he departed DFI.
Below, the video of windows booting. Notice that the CPU is based on the new C3 revision of the Phenom II core:
