Those voltages ranges are for manual setting. I would assume that auto and using a speedstep setting could go down to 1.05v. I've never seen a P5W allow manual voltages down to 1.05v.

I Just need to know if people using a 45nm CPU do have the 1.225-1.7v full range selection.

The above poster has a Q6600 though, that's 65nm....
