730/1710/1075 seams to be the wall. If I got above 730, evga precision says its unstable. I am hitting about 63c max, but once I put my leaf blower thermalake back on for exhaust I should be going at 60c again. I am thinking I have hit a wall and now need more voltage to add more mhz. Is there any way to mod the evga voltage tweaker software to work with my card? I don't know if I am comfortable doing a hard mod as I don't really know jack about soldering. Any ideas would be great as I am confident I have not hit a thermal wall.
