    GPU AMD HD7400M not detected as an OpenCL device

    l30nardosv

      Hi

      I have my computer (HP Pavilion g4-1387la Notebook PC) running Windows 7 Professional.

      I used the autodetect utility for downloading the appropriate driver for my gpu.

       

      The problem is that only the CPU is detected as an OpenCL device, but not the GPU. I know this is possible because initially the GPU was detected as opencl device but after upgrading to the new driver, it is not detected anymore.

       

      I tried uninstalling and reinstalling the driver amd-catalyst-15.7.1-with-dotnet45-win7-64bit  but it didn't work. Currently I it installed (crimson was not able to detect even any device)

      Could you help me please?

      Some info:
