Am I missing something or is this chip jacked?
Your PLL seems a little low, try 1.60v. Your VTT [FSB termination] is extremelly high for that CPU, try anything lower than 1.40v.
I have a different board from yours, but I run my SB voltage at 1.20v.
Also, what is the mix-max for your NB voltage? My P5E3 Premium has 1.25-1.80 or something like that; so 1.65v to the NB in my case would be rather high, so you might want to lower it I think [but, since I do not have the same board it is up to you].
Intel rates the voltage for the Q9450 up to 1.37~v, so IMHO 1.35v seems a bit high for 3.6Ghz. I'm able to boot into Windows with 3.6GHz @ 1.31~v, but since my RAM is not really supported by the board with 4 sticks at that speed, the moment I try to run anything it crashes within 5 minutes; if I just leave windows up it can stay on for a long time. I'm not really interested in trying to run my PC with anything less than the 4 sticks I own, so testing it with 1-2 sticks is a waste of time for me.
