My FSB speed works fine up to 231, then when I go to 232 it stops working. Whether its in the ocguru, or in the bios menu at startup it still hangs. I've been trying to read everything I can and haven't found an answer, so hopefully there is one 
I have
LGA 775 P4 3.0 Prescott D0 (SL7KK on the box and intel page said it was D0)
3.0 @ 3465mhz VCore: 1.3125v
FSB 231 NBV: 1.6v
ABIT AA8 Duramax bios v 17
Corsair XMS2 TwinX (2x512) PC5400 667mhz (4-4-4-12) at 1:1 (4-3-3-9) DDR2V: 1.9v
74GB WD Raptor SATA HDD
chaintec geforce 6600 gt pcie
thermaltake silent purepower 480W PSU
PCIE locked at 106, PCI locked at 33.33
Thermaltake tower 112 heatpipe hsf w/ AS5
Temps are running idle 37-40C and 50C max under load
other hardware: audigyz2, nec ide dvdrw
It only crashes when I try to put the FSB to 232mhz. I've raised the voltages up a couple notches each, but it still crashes when I put it up 1mhz. If ya need something else lemme know.
