    The CrossFireX internal bridge interconnects linking your CrossFireX graphics cards are not properly connected. Both bridge interconnects must be attached. For more information, see the user's guide for your graphics card.

    I have just reinstalled Windows. Tried both Dell's driver and AMD's driver.
    Windows recognize both cards (in Device Manager).
    BIOS on both cards: 012.020.000.027.037640.
    I have also tried to reseat the CrossFire cable.
    Nothing works, what should I do now?

    I received this exact same message when I was installing my 6970's. In my experience, the problem is either the crossfire cable itself, or one of the two cards has their crossfire connector not working. If it's under warranty I'd contact Dell and have them either replace both cards or the cable (or both). I went through all the checks before determining that my problem was related to one of the card's connectors (including doing several fresh installs of windows, different drivers, re-seating cards, etc), eventually I put my 4870's back in with the same crossfire cable and it worked just fine.

    So based on my experience you either have a bad cable (possible, but not my first choice based on my experience)...or, one or both of the cards crossfire ports is not functioning.

    Sorry that I don't have better news then that :(

    Thank Grey. The tech will come today and he will bring a new crossfire cable + 2 HD5870s.
    By the way, are my temps alright, they are hotter than the temps of my M17xR1? This is taken while browsing websites only (no crossfire).
    I remember that there was a thread about cooling mod for the PCH but I can not find it anymore.
