Overclocking
To find the maximum overclock of our card we used a combination of GPUTool and our benchmarking suite.
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.
Correct ROP count is 4.
The overclocks of our card are 910 MHz core (11% overclock) and 935 MHz Memory (17% overclock). Both overclocks are decent, but I'm not sure whether there is much point in overclocking a card in this performance class.
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 10.5%.
Temperatures
Temperatures are super low, that's why I would have wished that ASUS had reduced fan speed a bit to reduce fan noise.
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.
| Core Clock | Memory Clock | GPU Voltage (measured) |
---|
Desktop | 51 MHz | 135 MHz | 0.90 V |

Blu-ray Playback | 405 MHz | 324 MHz | 0.90 V |

3D Load | 823 MHz | 1620 MHz | 1.10 V |
