Well after much time digging around the maze of a website Intel has, I belive have found and answer to my own question.
Here bottom of page 14 & top of page 15 - http://download.intel.com/support/processors/pentium4/sb/30056103.pdf
It seems that the chip I have has the highest possible VID spec. that it can get, lucky me. :-)
Well Cheers. Maybe this info will help another.
