Overclocking

To find the maximum overclock of our card we used a combination of ATITool's successor 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 835 MHz core (8% overclock) and 1070 MHz Memory (7% overclock).

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 7.7%.

Temperatures


Due to the buggy fan control settings, the load temperature is quite low since the fan will run at too high speeds resulting in a lower temperature than intended.
