Overclocking

To find the maximum overclock of our card we used a combination of GPUTool and our benchmarking suite.
The overclocks listed in this section 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.


Correct ROP count is 16

Overclocks of our card are 915 MHz core (9% overclock) and 1200 MHz Memory (14% overclock). Overclocking potential is ok but not impressive. NVIDIA's GTX 550 Ti works a lot better here when considering clocks, with typical OCs in the range of 1050 MHz.

Overclocked Performance

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


Actual 3D performance gained from overclocking is 8.5%.

Temperatures

Temperatures in idle are fine, but load temperatures seem a bit higher than what I would have expected.

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.
