Overclocking

For our overclocking test we used the delivered software ASUS Smartdoctor. This tool allows you to adjust the core voltage and clock frequencies as well as the memory clock. The standard voltage regarding the GPU is 1.1 Volt. Using Smartdoctor you can rise this value all the way up to 1.5 Volt. Therefore we found the optimal voltage at 1.381 Volt. At this point it was possible for us to drive the GPU at 974 MHz and the memory at 5'872 MHz. Because of the power design which ASUS improved as well as the cooler that is more powerful by quite a margin we would have expected the HD 6970 DirectCU II to show better overclocking than the reference model. Unfortunately this wasn't the case. So there the only bit of hope left concerns extreme overclocking using liquid nitrogen as a coolant. Probably the card shows some more potential there.
