    512mb 7900GT vmod development thread

    i'd like a little help vmodding my new Legend 7900gt-sonic 512mb card.
    here are some pics. at this time i'd prefer smd-grabber or pencil mod options if possible.

    as far as i can tell vgpu is 1.3 at the moment and the samsung 1.2ns ram is being fed 2.11. i'll confirm as i start varying the voltages.
    stock clocks are 550/700 and very little overclocking is possible above these clocks.
    there also seems to be a problem with coolbits and these cards as my buddy killed his within a few hours after returning coolbits to default and going out for a few hours.
    when he returned the card was dead. so i reckon use atitool or something else for overclocking till we figure out what is going on with this style card

    below are a couple of pics that are exactly the same as my card and i've done a little research on the main vgpu ic.

    i plan at this stage to fix an smd grabber from pin7 to ground and start decreasing resistence on it from max downwards.
    please somebody confirm this will work or stop me from killing the card
    any other tips or tricks or information i should know i would greatly appreciate.
    i have no formal training in this field so what i know is more likely to be dangerous than not

    thanks for your input

    green are traces. blue is ground
    error correction LM35B is actually LM358 when magnified properly
    PSBAJ07 could be PS8AJ07 or o7

    and for reference
