Extreme overclockers are a wonderful specimen to behold. Whoever thought of taking liquid Nitrogen to a PC as cooling solution has to be a special person. That being said if it weren't for these mysterious human beings we wouldn't see exactly what the hardware we can buy is capable of.
Using an Asus Maximus VI Extreme, the ASUS OC Panel Corsair Dominator Platinum's and an all important liquid nitrogen evaporator, Mad222 has managed to push a Haswell CPU to 7092.68 MHz (69x 102,79 MHz) with two active cores and a voltage of 2.45V!

You can see the moment in the video below.
