EDIT: Just dawned on me that I have my coolant pump on the lowest setting it has. Been like that ever since I installed it as to keep noise down.
I've been running my PLL at 1.63 volts for nearly two years now with a q9550 at 3.8 Ghz ,8 gigs of Gskills over 1100 MHz and 2 hd4870's in Xfire.
there are a lot of voltages elevated to what has been muttered as unsafe here and there around the web and I never shut er down.
It folds 24 hours a day except for time out to play a game or two.
There seems to be a misunderstanding of what is safe and what is not.
Rule # 1 if you think its unsafe then it is.
Every system responds differently to voltage tweaks and you have to live on the edge a little if you want that extra 50 mhz of raw power.
My northbridge runs a tad over 1.4 volts and VTT 1.37 v ..cpu is 1.39 to 1.40
I'm more concerned with stability and registry integrity than where My volts are
your dual core will run all day over 500 FSB on this board if you'll just step on it a little and rework that water cooling.
I have chipset, gpu water blocks, and the CPU on the same loop and it hovers around 61C... all four cores 100% CPU utilization in the summer time and 50 deg in the cooler months .
I idle at or near ambients (27 at the moment) and its about 26C in my apartment.
and yea.
Turn that pump up.
If it dosent sound like a low flying airplane next to your computer then your not overclocked enough
