P4 1.6 Ghz On A Gigabyte 8itx Vcore Help

Hi to all

I need help on how i can increase my cpu voltage(p4 1.6ghz 478) with Cpu pin wiring mod or some other way because my motherboard (GIGABYTE 8ITX) doesnt support vcore changes from the bios or from dip switches.(default voltage of the cpu is 1.75) I have found this link http://www.vr-zone.com/guides/p4mod/ but it refers about the 423 p4 PIN OUT and i try to find something about the new 478 p4 pin out.

Thank you
