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 848 MHz core (11% overclock) and 1110 MHz Memory (17% overclock). Overclocking potential is OK, the card ranges about in the middle of the frequency range we have seen from overclocking our three GTX 560 Ti 448 Core 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 10.1%.

Temperatures

Temperatures in idle are great (but fan noise is fairly high). Under load the card gets quite hot (but noise is low). 82°C under load is still far from alarming, slightly lower temps would have been nice though because they give users extra peace of mind.

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.
