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 and voltage 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 805 MHz core (8% overclock) and 1160 MHz Memory (5% overclock).
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 6.3%.
Temperatures
The GPU temperatures are fairly low, my choice would have been higher temperatures for less fan noise.
