On Tuesday, ultra high-performance overclocking enthusiast x-powerx800pro wanted to prove to the world that Intel's Core i7 3770K can reach 6.6 GHz using a base clock multiplier of 63x and a clock speed of 6584.86 MHz (104.52 x 63). Nevertheless, the raw compute performance resulting from such a massive overclock results in a SuperPi 1M calculation in just 5.585s, breaking HiCookie's August 24th world record of 5.781s on Intel's 32nm Core i7 Extreme 980X. Of course, the chip being used is an Intel Engineering Sample, possibly from a great cherry-picked batch at that, but the results have nevertheless been validated in CPU-Z 1.60.

As a precaution, Expreview's page incorrectly identifies the chip as a 32nm processor, when it is in fact a 22nm Ivy Bridge engineering sample chip. However, more images of the achievement can be found here.
