7800GT Pencil mod questions

[CruSifiXken.Be]

I am planning to do a Pencil mod on my Msi 7800gt, but I don't really know exactly how to do it...
I have read that it is just pulling a line with a hb2 pencil...
But where do I draw the line?

A little help plz :(

Thx in advance

I don't think you can do a VGPU mod. Anyway, there is a thread on 7800 voltmodding here, why did you create a separate one?
