8800GT voltage mods

[DrMambo]

Thanks for that oohms, looking to do this soon.

Just to clarify, I'll be soldering the 200K VR in parallel with whatever that the green line is pointing to, for vGPU control?
*edit* Whoops, read it says 'to ground'. My bad :P
To read vGPU I need to connect one probe from DMM to the thing the green line points to and one to vGPU reading point? Or is it from vGPU reading point to ground?

And I'll assume to read vDIMM, it will be the same as the method for reading vGPU

What do you guys use as a suitable ground to solder to?

Thanks in advance.
