I have gone as high as 1.6 on my vcore and I have taken the memory as high as 2.425

my current 24/7 stable voltages are
Vcore 1.49v
DDR2 2.275v
MCH 1.25v 1.48v
ICHIO1.5v 1.70v
CPU VTT 1.31v
DDR2 REF 0%v
ICH 1.05V 1.25v

freq right now is 458x7 for the cpu and ram is on the 1:1 ratio so its like 916mhz
btw the ram is the Supertalent T8000UX2GC4
i have the latest bios

also I have the latest UGURU and it still freaks out at low temps where it goes from like 17c to 128c core temp shows it to be running at 14c idle. i have generaly found UGURU to be about 10 degrees off when its actualy displaying temps.

and the total up time i mentioned before is actually 6920h
