OverclockingTo 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 850 MHz core (6% overclock) and 1090 MHz Memory (9% 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 19% 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 PerformanceUsing 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 6.5%.
Temperatures are low, I would have preferred less fan noise and slightly higher temperatures.
Clock ProfilesModern 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.
|Desktop||50 MHz||68 MHz||0.93 V|
|Blu-Ray Playback||405 MHz||162 MHz||0.96 V|
|3D Load||800 MHz||1000 MHz||1.11 V|
