Overclocking
To find the maximum overclock of our card we used a combination of AMD Internal OC Software, ATITool and our benchmarking suite.
The final overclocks of our card are 931 MHz core (8 % overclock) and 1153 MHz Memory (21 % overclock). Compared to the AMD reference design clocks this is an increase of 13% and 28%. Both overclocks are good, I have a feeling that additional memory overclocks would be possible if the memory on the back of the card would be cooled as well. Also this card looks like a good voltmod candidate to me, of course doing so will void your warranty.
Temperatures
Compared to the temperatures of the regular air cooled reference design card there is not that much of a temperature difference. Still even about 10°C less helps improve the overclocking potential of the card.
