    I am trying to measure the vMEM on my 8800GTS, I found this guide http://www.vr-zone.com/?i=4641

    What I need to know is where is the ground spots on a gfx card?

    the metal bracket (that interfaces with pc case) or any of the metal rings around "screw" holes are classed as ground

    Edit: test for continuity between the metal bracket and points on your power connectors soldered points, including other contacts, if it is continuous with the metal bracket its ground

    Man, I wish I was able to help you.... but I dont have the first clue. I have wanted to do this, but way to scared and the write up on VR MOD isnt that discriptive.

    If you do this, do you think you could take pictures and a step by step?

    Awsome! I really cant wait.

    Like I said before... I really wanted to do the volt mod on my 8800 but everything that I could find on doing it, really wasnt that good of a write up ( 1 sentance intructions) and with very little pictures.

    Thanks again, and good luck! :toast:

    i would actually recommend connecting it to one of the ground wires on the pci-e power header because you wouldn't want any stray current or static discharge damaging the card
