    Invalid device HD 5800

    cymick

      I'm trying to get my current OpenCL program to run on my secondary video card. At the moment I'm running two Radeon HD 5800 cards (no crossfire) with a Windows 7 64 bit OS. The program compiles and runs just fine when I select my primary video card but when I try to select my secondary card it gives an invalid device error when I try to create command queue. The device shows up when I do a device query and I don't think I'm doing something wrong when selecting the device since I run the same exact process to pick my primary card. Are there any subtleties I should be aware of that may resolve this?
