Team Katana Japan Sets 3DMark 11 Extreme Record with 1747/7884 MHz @ 1.895V HD 7970

Citiraj:
Team Katana Japan set a new 3DMark 11 Extreme Preset single-GPU world record using their Radeon HD 7970 graphics card clocked at staggering clock speeds 1747 MHz (core) and 1971 MHz or 7.884 GHz effective (memory). These clock speeds were sustained using volt-modding (to maintain the right voltage stable), and liquid nitrogen cooling. The volt-mod was designed to override the OCP (over-current protection), and over-heat protection of the graphics card's VRM. The target core voltage was 1.895V.

The setup went on to bag a 3DMark 11 Extreme Preset single-GPU world record, where it scored X3757.69 points, bagging 1st Rank in HWBOT's "GLOBAL 1X GPU RANK" and "Radeon HD 7970 rank". Find the validation here. The GPU remained in the range of -145.0 °C (idle) -137.0 °C (load). The rest of the setup included a Core i7-2600K clocked at ~5.00 GHz, ASUS Maximus IV Extreme (P67), and a 1200W PSU.
