There are other things the VIA engineers did that I don't understand.

I couldn't get an answer from VIA whether this is the correct computation for the Nehemiah CPU or not. A while ago, somebody wrote to the list about not being happy with the default and investigating further. Maybe you can search the archives and contact that person to figure out what he found out. Or there's always the possibility of attaching a thermal probe to CPU case and use the thermal resistance values in the Nehemiah datasheet to correlate driver and voltmeter readings. ...juerg > Regards, > > c. > > >
