Clocks Change Back An Hour so the 12hrs you see in shot = 13Hrs
)

It took a bit of playing aboput trying to guesstimate the vcore.
The 1.425 is based on my p5k
bios setting 1.375v for the same clock + 0.0575 which was the droop i was seeing between
bios & load on the x38, that gives 1.4325v, on a whim I ran just below that.
Intrerestingly enough the actual according to cpu-z & mbm was 1.376v
comparing this to
Asus P5K @9x400 actual per cpu-z = 1.344v So I may leave it priming tonight at 1.40625v to see how that goes.
Update 29th
Reduced vcore & ran overnight, as i thought 1.40625vc has worked. When looking at the load vcore of 1.344v that's now the same as that shown on my p5k run so i'm happy.

VDroop
PQ6
Bios = 1.40625v
vcore idle = 1.392v
vcore load= 1.344v
vdroop 0.048v
Have read that increasing the
PCI-E Overvoltage Control and / or
FSB Overvoltage Control help reduce droop, i'll have a test and see if it does later.
