I wouldn't recommend upping the PLL either for 24/7 use, I've hurt plenty CPU's max fsb using high PLL voltage.

My board/chip is running prime stable at 533fsb with 1.55 vpll & 1.25 CPU vcore. The same chip has run for a couple of months @ 475 x 9.5 1.55vpll @ 1.4vcore.

Ideally Intel don't want there 45nm's going past 1.25v but I guess when you overclock best intentions & ideals go out the window.

yeah I also read that high vPLL could damage the chip. It would be nice to see DFI change the big steps in the bios for this voltage. Asus for example let's you control it with much smaller steps.

Still I find vNB a bit high. The P35 is 90nm so 1.55v isn't that high, but P45 is 65nm and needs less voltage. So when you take that in account, 1.55v seems rather high. I wonder if longterm high voltage has severe effects on this chipset or not.
