Running 750@1060 at 10c cpu and 9c case temp at idle. I think I'm ready for the big step, but I'm not sure about what resister to use. I think it might be 123k ohms but not sure. Is the kt7a mod different from the kt7 ? This is with core at 8.5v i/o at 3.5v., the chrome orb, and a 4-5 inch ac 120v fan in the side of the case. The case fan has a dryer exhaust hose going outside. I thought this might help until I decide on better cooling. Anyone know what resistor or potentiometer to use?
i used the 122k (widely available from radio shack) ... they come on a card with like 7 more .... worked for me :)
