    Graphics adapters from different manufacturers

    Gunter

      Hi,

      is it possible to use an HD 6990 for GPGPU applications, while at the same time the display is driven by an (on-board) graphics system from a different vendor? The on-board graphics chip is connected to the south bridge via PCI.

      We want to use Windows 7, driver 11.8 and SDK 2.3.

      Also, I have found that apparently a monitor must still be attached to the 6990 in order to make it work. For a rack-mounted server with multiple 6990s that's very impractical. Can someone from AMD give an authoritative statement about this issue?

      Thx

          I had a semi-similar situation with an APU and a discrete GPU -- at first, only 1 was being detected, but then after I had monitors attached to both, Windows installed the driver for the one it didn't previously -- and I am now able to use both regardless of if there's a monitor attached.

          Are you sure the device is inaccessible after you detach the monitor?

            headless GPU should work with latest driver and SDK2.5.
