    Do not worry about burning pull up resistors as somebody suggested, these pull up resistors are very large in value.
    so there's no need to remove any resistors at all?
    all that's needed is to bridge those contacts for up to 1.55v?

    i'm stilll waiting for my xfx card, but if the mod is really this easy i might actually try my first hardmod

    Yes, that's all there is.
    On the other hand, if you are not a skilled solderer, you can, as an alternative, solder the two larger points (more on on the edge of the board) to ground, that LardArse found to be in direct connection with point A (+0.2Volt) and B (+0.1 Volt) . That will give you up to 1.5 Volt

    LardArse,
    Why do you think that the two resistors indicated in some picture from you, remove the current limit. Where are these resistors connected to?
    According to the chip supplier the current limit is set with a resistor between point 10 and point 11.
    This is just one resistor instead of two.
    On the other hand, there is no mentioning until now if the current limit comes into action at all with the higher Vgpu.
    I would have expected that to happen with 1.5Volt and 750 Mhz.

    On his diagram he has 1.6V and 1.7V. I assume thats because he's using the VRM9 codes (aka replace resitor with 50K). Also, since I dont have a 7900GT (yet), could we get a better zoom shot of that area... where exactly is that in relation to the IC pic of the front?

    I dont think Cronic did the over-current protection, and he's well past 650Mhz. I dont think its needed up to 700Mhz.. not sure when? Not defeated over-volt protection really, since cant disable it.. just different way of over-volt mod... now in 2006 its digital :p
