Aight.. ford.. your settings/voltages don't look too far off mine, but the instant I go to 360fsb, it freaks out. Let's say I just wanted 400fsb even, I'm going to put out some 'guesses' as to what might work, then, if you're up for it, please tweak and re-post. And I'll give them a shot (I won't be an ass if something goes wrong).

FSB = 1600 (400mhz)
MEM = 800 (400mhz)
@ 9 mult = 3,600mhz

Voltages:
CPU Voltage = 1.6
CPU PLL = 1.6
CPU VTT = 1.5
Mem Voltage = 2.2
NB Core = 1.60
SB Core = 1.60
1.2v HT = 1.50
Bridge = 1.20

CPU GTL_REF Ratio = +30mV
NB GTL_REF Ratio = +30mV
DDRII Contr. Ref = DDR2_REF+30mV
DDRII Chan. A Ref = DDR2_REF+30mV
DDRII Chan. B Ref = DDR2_REF+30mV
