Dell :: T7600 Vs T7600G

A friend of mine works for intel in devolopment. So I been talking to him latly about the t7600 vs the t7600G . He basically said intel does not make a t7600G there is no such thing, he looked into it with a few of the other engineers. So this is what Im guessing, dell does something VERY simple to the t7600 that allows it to set a flag so the bios can detect it as a factory option and allow the overclock . . .So this is what im doing. Im bored until school starts up again (im a engineering student starting my masters in the fall) , I have access to a nems lab and engineering lab for 2 weeks before school starts. Im going to order a t7600 off ebay or here and ask my buddy to bring in his xps t7600G. Im going to test the pin outs in the lab and look for changes.

It must be a very small change and something simple that they do to allow it to throw a flag. So hopefully with a manual of pinouts I can test the i/o, resistance, etc and find the change.
