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 975 MHz core (5% overclock) and 1100 MHz Memory (5% overclock).

GPU overclocking potential is really nice - the best we have seen on any GTX 560 reviewed today. Memory on the other hand dissapoints, even though the same chips are use on all cards 1100 MHz is the lowest result we have seen today. Since GPU overclocking provides more performance gain than memory overclocking, overall overclocking potential is still good.

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 10.6%.

Temperatures



Even though the fan is very quiet, temperatures are also low. It looks like ASUS has found a great balance between noise and temperatures.

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.
