In cooperation with ASRock, HWBOT hosted the "ASRock 8 Series OC Competition.” The overclocking competition started on July 22 and ended on September 2. Participants from around the world competed in three different events: CPU-Z, Super Pi 32M and memory overclocking. Next to a bi-weekly prize for each of the events, and of course prizes for the overall event winners, ASRock provided a World Record bonus prize of USD $1000. DFORDOG from China took the bonus in the CPU-Z CPU Frequency stage by hitting a new Haswell top frequency of 7136 MHz. He used a Core i7 4770K, with all but one core disabled, liquid nitrogen, and an ASRock Z87 OC Formula motherboard.

Congratulations!
