Ivy Bridge 7 GHz Rips Through Pi

Intel Core i7-3770K is turning out to be a monstrous overclocker, when assisted with extreme cooling such as liquid-nitrogen. One such test-bed, was overclocked close to the 7 GHz mark, and put through Super Pi (1M and 32M), and PiFast. At 6961.6 MHz, the chip ripped through Super Pi 1M, in 5.187 seconds. The same chip, clocked at 6650.1 MHz, crunched Super Pi 32M, in 5 minutes, 2.843 seconds.

In PiFast, with a clock speed of 6805.1 MHz, the chip hammered out a total computation time of 10.56 s. NordicHardware compiled a comparison table using HWBot and its own data, to reflect how much faster a ~7 GHz Core i7-3770K is, at Pi. The rest of the known test-bed consisted of ASUS ROG Maximus V Gene Z77 motherboard, and 4 GB (2x 2 GB) of dual-channel DDR3 memory, clocked at around 2652 MHz, with timings of 7-11-7-28-1T.

Why does CPU-Z show only 4 threads (and not 8) in all three screenshots? could it mean that CPU-Z version to fully support 3770K is not out yet
because the benchmark isnt multi threaded. So to save on heat and power, and to achieve slightly higher clocks, he disabled HT.
