    5970 + 5450 = no Stream

    Gunter

      Hi,

      I know there is a thread about Nvidia and ATI in one machine, but I'm just trying to operate two ATI cards in one PC, and this doesn't work.

      I'm using Windows 7 64-bit, Catalyst 10.10, SDK 2.2, one dual-GPU card HD5970 and one HD5450. The configuration drives 4 monitors for an extended desktop without problems, but when I try to run calInit() the system hangs. FindNumDevices also hangs.

      Disabling either card and running cal on the other works fine, but of course this is not what I had planned. I only want to run my programs on the 5970.

      Any help?
