Team Katana Japan Sets Unigine Heaven World Record With AMD Radeon HD 7970

Team Katana Japan has set a new single-GPU Unigine Heaven Extreme Preset world record using an AMD Radeon HD 7970. They clocked the GPU to a staggering 1747 MHz core and 1971 MHz memory (7.884 GHz effective). This was accomplished using voltage mods to bypass and override over-current protection and over-heat protection; the GPU itself was cooled by liquid nitrogen. The core voltage on the Radeon HD 7970 was an insane 1.63V, with 1.895V for memory during the world record run. The system, which used an Intel 2600k at 5GHz on an ASUS P67 Maximus IV Extreme, managed to take home the world record for single-GPU setup in Heaven Bench with a score of 3757.69. The score gave Hideo and Team Katana the #1 spot in HWBOT’s “Global 1x GPU Rank” and “Radeon HD 7970 Rank”. Validation of the world record can be found here.
