Overclocking

To find the maximum overclock of our card we used a combination of GPUTool 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.


Default clocks are misread by GPU-Z, the correct values are 700/900/1400, correct ROP count is 4.

The overclocks of our card are 833 MHz core (19% overclock) and 1065 MHz Memory (18% overclock). This overclock is very respectable and enables willing users to get some nice extra performance out of their card.

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 from overclocking is 18.8%.

Temperatures

Temperatures are fine, everything ok here.

Clock Profiles

Modern graphics cards have several clock profiles that are selected to balance power draw and performance requirements.
The following table lists the clock settings for major performance scenarios and the GPU voltage that we measured. We measure on the pins of a coil or capacitor near the GPU voltage regulator.
