Overclocking
To find the maximum overclock of our card we used a combination of ATITool's successor and our benchmarking suite.
The final overclocks of our card are 691 MHz core (26% overclock) and 424 MHz Memory (27% overclock). That's one amazing overclock. NVIDIA's same G96 chip is also used on the 9500 GT where it is running at a higher clock speed. It also looks like the DDR2 memory has some headroom left too, which isn't hard given the lousy default clock of 333 MHz.
Temperatures
Even though the card does not use any form of active cooling, the temperatures stay comfortably low. This is a good sign for users of small media PCs because such cases usually have limited airflow which in some cases makes passive VGA cards overheat.
