I have heard that on the SB700 you run into a wall at clocking above 3.299ghz. Is this true? I have tried on my old processor which was a X2 7750 BE, and found it to be unstable above 3.245ghz with my current board NB780G/SB700, (see signature for rig specs) I switched to a X4 940 BE and didn't want to push it until I ask.
