The Guru of 3D posted an article about overclocking GeForce GTX 480 with extra GPU voltage
Yesterday we released an update of AfterBurner, we implemented and thus added voltage control for the 470/480 cards in MSI AfterBurner revision 1.6.0 beta 4 and upwards. Now as you guys probably know the default clock frequency for the GeForce GTX 480 is 700 MHz on the core, 1400 MHz on the shader domain and 3700 MHz on the memory.Overclocking GeForce GTX 480 with extra GPU voltage
With an additional voltage we where able to push close to 850 MHz on the core. The first group of people that will really benefit from what we'll show you today are the people that opt a liquid cooled GeForce GTX 470 or 480. Well read the next couple of pages with a step-by-step guide and then we'll show some results based on our overclock experience.
