Overclocking

If the card runs in 2D mode it is very silent and you wont be able to hear it. Also compared to a GeForce 285GTX or a ATI Radeon HD4890 the 5870 is much more quiet. In 3D mode the cards noise level still is on a very reasonable level and this let's us think that it might be an interesting object to be overclocked. Using the delivered software SmartDoctor you can raise the core voltage slightly and achieve quite astonishing clock rates. Generally we can claim that a higher core voltage (max. increase ten percent) results in better overclockability.
With the fancontroller set to 40 % we were able to reach a core clock of 820 MHz and memory speeds of 2400 MHz.
