    7200GS Vmod

    Hey guys

    in march i like to organize a LN2-Session with my two friends, we will buy a Asus P5K to bench Superpi with my E8400, besides we like to vmod the board, but we are new in moddingscene, so we will start with modding a Gigabyte 7200GS to get skill. But i didnīt find a description for this GFX, so i want you to explain me how to mod this card, it would be nice if you add a list of material we need, because i donīt know what we need for modding, just a soldering gun :p Here are pics of the background :






    I hope somebody can help me, i would feel really happy Thanks Chris

    Please measure the resistance between pin 4 of the RT9259A and ground (the dustplate for example). Can you make a picture of the top of the card as well?

    the bottom middle pin in the picture - reads 1.013- 1.014 ... is this the proper pin as the top middle (4) doesn't read anything

    TheGoat Eater,
    That's the correct pin. Assuming that measurement of yours means 1.013kΩ then vGPU mod would be 20kΩ VR to ground from pin#4.

    A good vGPU measuring point would be the legs of the big yellow copper coil marked as "L11" on the silkscreen.

    That's absolutely brutal performance right there!


    GPU-Z seems to be confused with the vRAM freq though...
    Or is it?

    That sure is a hell of a score.
    Better order a Tek 4.0 immediately
