Why would a T-bird 900 run at 1.8v core when the mobo is set at default or 1.75v?

[Macro2]

The Bios reports 1.79v and motherboard monitor reports 1.80v when the mobo is set at default (pro2a) which I thought was 1.75.
Setting the bios at 1.75v still yields 1.79v and 1.80v.

Is the Bios wrong or the sensor wrong? Should I kick back to 1.7v or just leave well enough alone.

PS...Has anyone else had MBM 5.08 crash their system?

I say just leave it... it won't have any serious effects on your CPU anyways... T-Bird chips can safely run at up to 1.85V...

Some motherboards give slightly more voltage which can help stability,nothing worst then a CPU not getting enough voltage,anyway my own T-bird 900 also on a MSI board is reading 1.78v so I would not worry and leave it at that setting.
