    I'm having some trouble overclocking this card (1gb version) using RBE. When I change the dashes to a value of voltage (yes I read the FAQ and know what the dashes mean) and flash the bios, my card is not detected after restart. Any ideas on how can I give my card more juice since I'm struggling to overclock it with standard voltage?
    Besides that, i can't go beyond 700/1000 without problems with default voltage, guess I'm not very lucky with this card.
    Thanks

    Ofcourse... at some point, like any other processor. And I dont think you can increase voltage through rom because its already at highest: 1.20v
