Overclocking
To find the maximum overclock of our card we used a combination of Rivatuner, ATITool and our benchmarking suite. In order to enable overclocking of the G94 cards using Rivatuner, you just edit rivatuner.cfg and add the device id in our case "0622h" to the G92 section.
The final overclocks of our card are 787 MHz Core (21 % overclock) and 1082 MHz Memory (20 % overclock). Those are some very impressive numbers, especially when you consider that the Zotac Amp! Edition "overclocking" card managed only 740 MHz.
Temperatures
For a single slot cooler, these are very nice temperatures. Unfortunately the cooler tends to be noisier than necessary as mentioned before. I would have prefered a bit higher temperatures with less noise.
