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 998 MHz core (5% overclock) and 1205 MHz Memory (10% overclock). Almost 1 GHz! For a GTX 560 Ti this is pretty impressive. The other GTX 560 based cards we have tested so far were able to reach between 900 and 950 MHz. Memory is slightly lower than other GTX 560 cards, but not by much.

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 5.6%.

Temperatures

Temperatures of the card are high which is caused by the high power consumption and the fairly weak cooler.

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.
