    APP SDK 2.4 OpenCL version problem

      version 1.4.879 required, 1.4.815 installed

      I've seen a similar problem reported elsewhere for earlier SDK revisions, such as in this thread:


      though I didn't see a resolution.  Under 64-bit Windows 7, I've installed Catalyst 11.5 and the APP SDK 2.4, and my graphics device is an ATI Mobility Radeon HD 5470.  When I run any of the OpenCL samples, the error:

      This OpenCL build requires version 1.4.879, version 1.4.815 installed.

      is displayed and the GPU is not usable.  Any idea of what to try to resolve the problem?  I've uninstalled and reinstalled both the SDK and Catalyst to no avail.  Thanks in advance!

      BTW, I hesitate to perform a driver clean due to this post:



      The output from clinfo is as follows:

      *** CAL version mismatch:
      This OpenCL build requires version 1.4.879, version 1.4.815 installed.

        • APP SDK 2.4 OpenCL version problem

          More info...  Even after installing Catalyst 11.5, the driver version as reported by DeviceManager remained at 8.712.1.2000 from 4/15/2010.  Updating the driver via the Device Manager found an update and installed it with version 8.770.2.1000 from 9/19/2010.  Considering that the Catalyst 11.5 release date is 5/9/2011, this still seems like a very old driver to select. 

          What driver version should Catalyst 11.5 be installing for the ATI Mobility Radeon HD 5470?  Are the driver files themselves extracted somewhere such that I can tell the Device Manager update process to use them directly?

          [ With the new driver version, I am still exhibiting the same version problem as I previously reported, and even the Geeks3D GPU Caps Viewer v1.11.1 also confirms that there is no GPU OpenCL device available. ]




            • APP SDK 2.4 OpenCL version problem

              AFAIK this should be related to that the previous driver was not installed properly and you tried to upgrade that with the new 11.5 driver.

              I understand your concerns mention in the thread but sadly this is the only course which can help you.

              I would also like to suggest to try older SDK say 2.3. I would like to tell this is unofficial suggestion as I think the previous SDK would require less recent driver and you might get your opencl running.

                  Thanks for the reply.

                  I hadn't presumed the original driver was installed incorrectly - it is the same one that was installed on my laptop when I purchased it, and this is the first time that I had tried to modify it.

                  What files/registry settings/etc. does the cleaner explicitly look for?   It would be better if I could remove files by hand to verify what actions are taken.

                  Actually, what specific driver file is consulted to obrtain the 1.4.815 version number?  I've viewed file properties of various driver files, but none appear to correspond.  If I could tell exactly what was out of date, that would help.

                  When I tried to install v2.3 of the SDK, but a dialog box appeared indicating that no supported GPU devices were found, but I could continue installation with a CPU device only.  The latest, 2.4 SDK, doesn't display that message.
