So it seems to be that i cant get orthos stable with the fsb higher then 425. Anyone know why that is. Could it be that i need to raise the voltage. Check out this overclock run too as it might help you understand what im going through.

up the cpu-voltage one notch or 2
if that doesnt work try up one notch then add more voltage to the ICH/MCH/FSB but by one notch on those. have you tried running memtest86 on the ram to see if it is getting errors @430mhz?
