SSC are sort of binned GPU's and mostly run at slightly higher volts then vanilla's..; I had 3 vanilla cards ( 2 EVGA and one POV) and all capped out around the same shader speed for benching (480 region) GPU around 745 and rams were at 1250-1300 max,;

Very nice clocks T-Flight, praise yaself lucky mate hope the tuner brings out even more !!
