Its there somewhere, dont have cpu-z in front of me at work. But as to the significance, there is a theory floating around that the lower the VID the better the chip can overclock.
1.53. Thats pretty high considering other people are doing it on 1.47-1.49. I'm kinda disappointed cause I really wanted to get atleast a 3.6-3.8. I underclocked my ram pumped it to 1.55 as the highest but can't boot into windows. I've tried giving the NB some voltage even though I know it doesn't need it at 360fsb but of course that didn't do sh!t
