eVGA 6800 Ultra - PCI-E Video Card -
eVGA ships this card at its stock speeds of 400MHz (GPU Core) and 550MHz (Memory clock). For those looking to squeeze more performance out of things, you can use NVIDIA coolbits or a utility like Powerstrip to raise the speeds to slightly faster levels we nailed 435MHz on the core and 675MHz for memory which yielded an overall performance increase of 10-12percent depending on the application. Your results may differ depending on a number of variables such as Power, cooling and RAM.
