I'm trying for 3.6GHz which should not be a problem considering I was stable at 3.3 without adding much if any volts. I just don't understand why it is so damn hard. Nothing makes sense with this board. I understand what is happening with the CPU GTL but the board doesn't seem to follow logic at all. It is like trying to break a combination lock - you just have to get lucky...

Can someone tell me what the minimum VTT I would need to set to achieve 450MHz FSB? I don't want to keep guessing with that because with every change in VTT I it seems I have to redo all my other settings.
My Q9450 was stable at FSB 450MHz with FSB Termination Voltage 1.24V in BIOS or 1.14V real and CPU GTL Voltage Reference 0.63X and NB GTL Voltage 0.67X.

With my Q9650 I don't need more than 1.20V in the BIOS or 1.10V real.
