    but OpenCL support only CPU no GPU support

    but not help me , it's always have version 851.1 and support only CPU OpenCL

    Your CPU, has a GPU on it. That's what an APU is....

    be unrelated .

    before uninstall this driver package.
    OpenCL have 3 devices (CPU , HD 6520G , HD 6650M)

    but now support only CPU (Number of device = 1)


    and desktop HD 6850 has same problem.

    A reformat may be in order mate, that's what I had to do after trying to uninstall those 8.92 questionable drivers. I imagine 8.93's are no different..

    A reformat may not be necessary.


    @V-FrIeNd
    Uninstall your current driver, restart.
    Go here.
    Click 'Run Now' and it'll download a small-ish .exe file.
    Run that, and click 'Accept'; it should start downloading things.
    After that, click to detect your problems; any choice is fine.
    After a scan, click 'Uninstalling'; this'd lead to a bit of a lengthy scan.
    After the second scan is done, look for 'AMD APP SDK Runtime'.
    Click 'Next', and then 'Yes, try uninstall'.
    After that, just click 'Next' until it's done.

    If you saw 'Catalyst Control Center' when you ran MS Fix it, uninstall that too by running Fix It again, using the same procedure as when uninstalling 'AMD APP SDK Runtime'.

    After that, run DS 3.2.0, don't reboot.
    If possible, run TwL's cleaner too, from a command prompt with an elevated credential (i.e right-click Command Prompt, Run as administrator); don't forget to extract the files first.
    Run CCleaner for a registry fix, and then run Auslogics Registry Cleaner.
    Don't forget to also select 'Advanced Categories' in Auslogics.

    Restart, and try installing a proper driver again.
    Don't know if it'd fix your problems, but I have a 11.11b running fine after trying that sh!tty 8.93 22 Nov; OpenCL and everything is properly detected.

    I try @k1net1cs method

    APP SDK is always 851.1 version.

    and opencl has 1 device (CPU) only.

    Hmm...that's strange.

    'k, this sounds a bit 'drastic' but try installing the 8.93 driver again.
    After everything is working (after restarts and all), run the Setup.exe again to uninstall it.
    Don't forget to clean it post-uninstallation.

    In any case, this is mine post 8.93 uninstall and 11.11b install.

    1. Did you try to run CL GPU demos?
    2. Try to include GpuCapsViewer.exe into High Performance GPU whitelist in Vision Engine and then run Gpu Caps Viewer.
