Wow....3Ghz easy!! (204x15) I just bumped the voltage to 1.475...and that is with some lame Thermaltake HSF!!! I have not put on the Freezer Pro yet. I only swapped chips..I could not wait..hehehe. I cant wait to get this on the Mach 2 II!! Think I am going to have to put it back together for a bit without a new case. I want to keep dinking with this thing tonight and put that other cooler on it. This is to cool to just hit 3Ghz w/out stressing anything. Maybe tomorrow I will try the Mach 2.
