Overclocking

To find the maximum overclock of our card we used a combination of ATITool's successor, Furmark and our benchmarking suite.
The overclocks listed here were achieved with the default fan settings as defined in the VGA BIOS. Please note that every single sample overclocks differently, that's why our results here can only serve as a guideline for what you can expect from your card.



The final overclocks of our card are 735 MHz core (13% overclock) and 1400 MHz Memory (13% overclock). Both overclocks are amazing and show how much potential is left in NVIDIA's new 55 nm design.

Overclocked Performance

Using these clock frequencies we ran a quick test of Call of Duty 4 to evaluate the gains from overclocking.


The actual 3D performance gained is 8.1%.

Temperatures

Temperatures are fine, there is a good balance between fan noise and temperatures. Personally I would have chosen an even slower running fan in idle to reduce fan noise even more. Something like 60° in idle wouldn't hurt the card at all but reduce the emitted noise further.
