Let’s start with what a stock GeForce GTX 580 videocard should be running at. According to Nvidia, the GPU in the GTX 580 is rated to run 772MHz. Nvidia pegs the shader clock at 1544MHz, and the 1536MB of GDDR5 is supposed to run at 2004MHz (effective). What’s the fun in that?
Sure, the GTX 580 is already the fastest single-GPU card on the planet, but that didn’t stop overclocking guru Shamino, who works at Asus, from putting the pedal to the metal. Shamino jumped straight into LN2 cooling, and by doing so he was able to crank the GPU all the way to 1519MHz, nearly doubling the stock clock. The memory, meanwhile, was pushed to 2500MHz.
The extreme cooling was necessary, both to accommodate the higher clockspeeds and the handful of volt mods Shamino made to the card.
