I only do water cooled so I will post 5.0 and 5.1 runs..I decided to use EVGA's Precision X software..Im a bit green with Nvidia..I have forgotten..the nice thing about there software is you can bench it and see if it will crash but un-like afterburner the voltage increase is a bit lacking..everything I have run is with stock voltage..I clocked it a bit but never raised the voltage of the 690....yet
