We have updated the list of AMD products supported by the early release of the OpenCL 2.0 driver. You can find that list here:
The original page listed supported product families, but in some cases particular items within the family were not supported. Ouch.
We were alerted to the problem by a couple of people here on the forum, in this thread: http://devgurus.amd.com/thread/169453
This should be fixed now. That improvement was driven by your feedback, which is why I am a real believer in forums. We will never know how much pain was saved for your colleagues going forward, but we know the world is an ever so slightly better place. Somewhere a unicorn is smiling. So thanks for helping someone else, and apologies for the confusion caused by the first version.
