In CPU-Z if you go to the About tab and click on the Registers Dump button it will at least give you your Maximum VID value for whatever that's worth. It reports 1.325 for my Q6600.

I think too many users have been comparing Maximum and Minimum values from different software and different versions of the same software while running on different motherboards. I hope more users post some data so we can see if there's a pattern here. At the moment, most of the VID data that's been posted in forums is useless.
