Thread: ATI Crossfire, 2nd card LED light doesn't show?




  1. #1

    Default ATI Crossfire, 2nd card LED light doesn't show?

    I have dual X1900 XT's running in Crossfire

    DXDIAG REPORT
    Computer:

    Video Card:


    The slave card's LED does not light up, and even with Crossfire Enabled, 3dMark doesn't report that I have two cards.

    What's up? What can I do?

    Your images only show the DXDiag screens. To enable software based CrossFire with the 2 boards you need to enable it in the Catalyst Control Panel. Make sure you have done this before doing any testing as this is the only way I am aware of to get both cards talking to each other.

    Thanks. Catalyst control panel says Crossfire is enabled, but I just have to take it's word for it.

    Why isn't one card's LED lighting up?
