Overclocking

To find the maximum overclock of our card we used a combination of GPUTool and our benchmarking suite.
The overclocks listed here 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.


Due to a bug in GPU-Z the shaders are reported incorrectly as 224, the correct number is 336.

The overclocks of our card are 848 MHz core (5% overclock) and 1070 MHz Memory (7% overclock). Even though this overlock may look small it should also be considered that the card comes overclocked out of the box which already represents 20% core and 11% memory overclock.

Compared to other GTX 460 cards, it seems that all GTX 460s hit around the same maximum overclock no matter if overclocked out of the box or reference design.

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 6.0%.

Temperatures

Temperatures are low, so is fan noise. If you want your card to be even quieter there is still plenty of temperature head room for manual fan setting tweaking.

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.
