    I put together a little blog guide thing of volt modding the 4850. It might help someone who is new anyway. Click here.

    I managed to bench at 975mhz with an MCW60.


    Just finished vmodding the 4870 then...


    So... wonder how many volts it takes to kill these things?

    Approx 1.42v


    I just had a quick bench with the 4870. Seems like it doesn't like voltage as much as the 4850. Max on stock volts was 890mhz. Bumped the voltage by .1v and i hit 950mhz. Then not a single mhz more, regardless of voltage.

    Anyone else experiencing similar things? Or have i just hit the limit of the card?
