The GeForce GTX 580 sets a new Vantage record

Renowned overclockers elmor and Kinc did the unthinkable, breaching the 1500 MHz barrier for the core (geometry domain) clock speed of GeForce GTX 580. Using ASUS EN580GTX DirectCu graphics card, the duo managed to achieve 1504 MHz core, 3008 MHz CUDA cores, and 1253 MHz (5012 MHz GDDR5 effective) memory, churning out 240.6 GB/s memory bandwidth. With this in single-card configuration, the testbed consisting of Intel Core i7-990X clocked at 6.14 GHz and 6 GB of DDR3 memory clocked at 1750 MHz, and ASUS Rampage III Extreme motherboard, the duo achieved a 3DMark Vantage score of P45819 (performance preset), setting a new record.

The bench was powered by a 1200W Antec HCP PSU, the graphics card ran with a whopping 1.62V vGPU, and 1.86V vMem, it is estimated that the graphics card drew 600W (12V, 50A) of power in itself. The CPU and graphics card were cooled using liquid nitrogen evaporators, the GPU VRM was directly air-cooled, using a high-flow fan. A number of hard volt-mods were employed to achieve those voltages.
