ASUS P5Q-E (P45) pre-view

I think your 1.66 CPU PLL voltage is high for a daily use, expecially because you are running a 45nm CPU.
Real voltage, considering mobo overvoltage, must be 1.70-1.72 or even a bit higher.
Are you sure you need so much? I think that around 1.54 (bios setting) can be enough, I would no go much more high with a 45nm CPU for daily.

to improve bandwidth first try to enable "Static read control", it improve performance but decrease stability, test it and if all is good try to lower performance level. I don't know if you read P5Q DL discussion, however, the 1:1 FSB/RAM is the worse divider for PL (13... max 10...), for better PL (max 8... or 7 if you are fortunate) you must use other divider.

Thank you! I think I can get it to 1.58 stable by increasing CPU GTL's about .02 each, 1.54 & 1.56 were no-go. I even killed my BIOS and had to recover then flash to v1201 when I started playing with NB GTL (it is back on auto for now).

How high is a safe CPU GTL with 45nm and Vcore set at 1.22750 in BIOS?

Yes, I am aware of the 1;1 issues but I want to find the 'fairly reasonable' topend of the chipset and am still very early in testing this board.

I may just back down a bit on some voltages and run a lower fsb with divider to boost the RAM... but I am actually getting close to my old P5K's stats when it was at 461/1224 and maxed out.
