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.



The overclocks of our card are 973 MHz core (5% overclock) and 1065 MHz Memory (7% overclock). The number "973" immediately pops out here, showing an excellent overclocking potential considerably higher than all the other GTS 450 cards tested today. The explanation is simple: ASUS is running their GPU at 1.28 V while most other cards are using 1.08 V. Such an increase will improve the overclocking potential of the card immediately, but also power draw, heat and noise.

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 4.6%.

Temperatures

Temperatures are fine, everything ok here.

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.
