The included ThunderMaster OC utility is similar in layout and functionality to MSI's Afterburner and EVGA's Precision X, offering clock/voltage monitoring and adjustments and the ability to load/save profiles. The utility interfaces with the Nvidia driver API which does not allow voltage adjustments (the Core Voltage setting in the illustration below only locks the 3D voltage at 1.175v, which hinders any meaningful overclocking). Power limit on this board is restricted to 128%, which is 217.6W (base is 170W).
The point of this test is to determine the dexterity of the cooling solution (leaving the fan speed at AUTO will just mean the fans will ramp it when temperatures hit 70, which doesn't provide a controlled environment for science)
On the highly demanding Furmark 1.9 burn-in test, 100% fan speed (makes a huge ruckus but pushing a lot of air) kept the card cool at 61 degrees celcius. Typical temperatures in games should be around 40-50 degrees, which is an excellent result.
We managed to squeeze an additional 115MHz out of the core (taking the boost clock to 1.2GHz) and an impressive +328MHz from the memory. Your actual milege may vary due to the ASIC "lottery".
