Windows 7 and mixing graphics cards

    grrr :mad:

    Moved over to Windows 7 expecting it to resolve my multi monitor issues I had with Vista and different graphics cards. But no luck.

    I use 4 monitors on my work PC. Under Vista I was able to get the setup working by using 2xPCI Radeon 9250 128MB cards and their 4 outputs. But ATI had released no drivers for these legacy cards so I was stuck using Vistas built in ones which where rubbish.

    I've now moved over to Windows 7, and had hoped I could mix PCIe with PCI under this OS, but no luck. I can either use the PCIe card or the PCI card, not both.

    Under my device manager I can see all the cards, but the PCI ones are giving me the error: "Windows has stopped this device because it has reported problems. (Code 43)" and are using the default XDDM drivers from Windows.

    Is anyone successfully using a PCI card and a PCIe card together? Or does anyone know how to fix the error with the PCI cards?

    Bad move

    new OS's aren't a magic solution to problems, if something isn't patched in the old OS and the new OS doesn't specificaly state that it is now supported then it's just a gamble.



    Stupid questions, what card is setup as default in the BIOS ? - try swapping if there is an option

    what card is the PCIe ?

    you could try
    PCIe with two monitors and
    two PCI cards with a single monitor, driver support might be better

    It wasn't a gamble. MS did state that the requirement for cards to be the same (or at least use the same driver architecture) in Vista would be removed with 7. What I'm seeing though is that this may be only possible with DX10+ cards.

    The PCIe card is an x1800GTO.

    The specific thing which 7 changed over Vista is that it allows two graphics cards from different manufacturers to work at the same time. But they both need to be WDDM drivers, I don't think it's possible to mix WDDM and standard XP drivers.
