Currently everything on Auto, except:
CPU Multi - 10.0
V DIMM - 2.10

Running OK with these settings. Going back to 9.0 multi and raising FSB from 333 stock to 340 = crash loading Vista at CPU voltage from auto to 1.7.

It's BIOS 0406 Beta BTW.

Okay, try this for starters:

Extreme Tweaker
Ai Overclock Tuner : Manual
OC From CPU Level Up : AUTO
CPU Ratio Control : Manual
- Ratio CMOS Setting : 10
FSB Frequency : 400
FSB Strap to North Bridge : 400
PCI-E Frequency: 112
DRAM Frequency: DDR2- 1066
DRAM Command Rate : 2T
DRAM CMD Skew on Channel A: AUTO
DRAM CMD Skew on Channel B: AUTO
DRAM CLK Skew on Channel A: 300
DRAM CLK Skew on Channel B: 300
DRAM Timing Control: AUTO (This is same as):

Primary: 5-5-5-15-3-AUTO (for 52)-6-3

Secondary: 8-3-5-4-6-4-6

Tertiary: 14-5-1-6-6

DRAM Static Read Control: Disabled
Ai Clock Twister : Moderate/Strong
Transaction Booster : Manual
CPL: 6

CPU Voltage :
CPU PLL Voltage : 1.50 - 1.56
North Bridge Voltage : 1.49v - 1.55v
DRAM Voltage : 2.1ov
FSB Termination Voltage : 1.300 - 1.36v
South Bridge Voltage : 1.100v
Loadline Calibration : Disabled
CPU GTL Reference : AUTO
North Bridge GTL Reference : x67
DDR2 Channel A REF Voltage :
DDR2 Channel B REF Voltage :
DDR2 Controller REF Voltage :
SB 1.5V Voltage :

NB LED Selection : NB Volt
SB LED Selection : SB Volt
CPU LED Selection : CPU VOlt
Voltiminder LED :

CPU Spread Spectrum : Disabled
PCIE Spread Spectrum : Disabled

With the Loadline Calibration disabled, if you haven't done the pencil mod, you'll need about .1v to make up the difference in vdrop (note, not vdroop).

Goodluck,

Richard.
