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 670 MHz core (15% overclock) and 2190 MHz Memory (16% overclock). When compared to the NVIDIA reference design clocks, the overclocks are 22% and 29%. Quite some impressive numbers I have to admit, and the overclocking process was really easy. All I did was click "Find Max" three times in GPUTool and everything turned out right. Compared to the MSI GT 240, which required some special tricks, this baby was as easy to OC as it gets. It should be noted however that Palit's card has a higher power draw under load as the card from MSI for example, which is probably caused by higher 3D voltages that help with the overclock.
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 18.3%.
Temperatures
Temperatures look good, personally I would have liked to see all temperatures shifted by +10°C and got less fan noise in return. Nevertheless, the cooling solution does a nice job, even with 20% overclocking, the temperatures go up by only 2°C.
