Bios 1,27 V
DMM 1,31 V

weird... i think this is a bug.

So don´t set 1,25 V for NB
Yes, the lowest voltage setting in ASUS BIOS doesn't give the lowest real voltage, and it is also connected to FSB.

On my P5K3 Dlx, I found:

at 333MHz fsb, vmch 1.25v in bios, results 1.236v by DMM.
at 400~450MHz fsb, vmch 1.25v in bios, results 1.536v by DMM.

so basically, 1.25v in bios at high fsb, equal to 1.55v set in bios on my P5K3 Dlx.
