That's almost twice the processor's stock speed, and to get there, the overclocker had to keep a steady stream of liquid nitrogen flowing to keep things chilly, especially since he jacked up the core voltage to a gut wrenching 1.872V.
According to the person responsible, the insane overclock is "probably the world's best," and we won't argue his assumption. Although it is worth mentioning that he was unable to run any benchmarks, which isn't surprising since the goal was to overclock the chip as high as it would go regardless of whether it was stable or not.
