Overclocking

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.



Maximum stable clocks of our card are 830 MHz core (13% overclock) and 1160 MHz Memory (22% overclock). GPU overclocking is decent, even though we have seen higher clocks from other GTX 560 Ti 448 cards tested today. Memory overclocking works very well on the other hand, delivering the highest clock frequency of all reviewed cards.

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 12.7%.

Temperatures

Temperatures are super low in both idle and load. Unfortunately fan noise is higher than what we had hoped for. In my opinion it would have been better to find a more balanced setting between noise and temperature.

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 important performance scenarios and the GPU voltage that we measured. We measure on the pins of a coil or capacitor near the GPU voltage regulator.
