Never mind... you guys ready for this? Here you go, 500MHz at LAST!

I think that's all I'll do at this point... it's time for good ol' X3350 to take her break. I have been pushing her quite hard the last few days.
And by the way, batch #: L803B196
Now I'm even more positive that a X38 or X48 motherboard would be able to go beyond 500MHz, or at least be able to do more at 4.00GHz than my board... probably... hmm... they can even keep this FSB 24/7 stable! Oh yeah, and voltages needed for 4.00GHz:
VCore: 1.500V BIOS, 1.492V CPU-Z
PLL: 1.80V
VDimm: 2.30V (just to be on the safe side)
FSB Term: 1.50V
NB: 1.71V
SB: 1.20V
SuperPI 1M at 4.00GHz is 12.500s.
