Overclocking
To find the maximum overclock of our card we used a combination of Rivatuner, ATITool, nTune and our benchmarking suite.
The final overclocks of our card are 749 MHz Core (25 % overclock) and 1106 MHz Memory (11 % overclock). I was totally surprised by these overclocks. From a dual GPU design like this I expected no, or almost none overclocking at all. This is another fact that NVIDIA's new cooler design works well and is an excellent innovation.
Please note that the core clock of both GPUs is dependent on the PCI-Express clock signal, just like on the GeForce 9600 GT. Please read our article

For such a powerhouse the card runs very cool and silent, no surprises here either.
