It was not long ago Corsair broke the world record for DDR3 clock frequency, but now the record has been broken again and with quite a margin. Romanian overclocker Matose has pushed his Kingston HyperX 1T memory stick to 3600 MHz!
Matose used an AMD FX processor to reach these extreme memory speeds and with some help from liquid nitrogen on both CPU and memory on an ASUS ROG Crosshair V Formula motherboard he managed to reach a final clock frequency of 3600 MHz, well over the 3467 MHz that Corsair reached.
The 1GB Kingston module operated with 10-13-13-31 timings and the is almost twice as high as the reference speed most enthusiast modules ship with, 1866 MHz.
