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.



The overclocks of our card are 930 MHz core (3% overclock) and 1180 MHz Memory (12% overclock). Compared to the NVIDIA reference GTX 560 that we have, the maximum overclock for both memory and core is slightly lower, but this could also be explained that we got an "unlucky" sample.

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 2.6%.

Temperatures

Temperatures are extremely low, but fan noise is too high under load. The better solution would be to let temperatures go up by like +10°C, which allows a slower fan speed reducing fan noise considerably.

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.
