please tell me -exactly- which catalyst version and which stream sdk you have installed. latest are cat v10.8 and sdk v2.2. the ATI release notes say that the Mobility HD 5470 is supported which is a good sign. however, can you please paste the output of the CLInfo.exe program as well? it is part of the SDK installed here: ...\Documents\ATI Stream\samples\opencl\bin\x86\CLInfo.exe

no idea then, sorry. maybe it has to do something with the binary kernels machinecode issue on some mobile devices ( http://forums.amd.com/devforum/messagevi...did=138232 ). but since i can not reproduce it i can not fix it. all we can do (as always) is to wait for a fixed opencl runtime.

[Rolf]

Right now, it depends on AMD to fix the issue.
But here's a workaround: roll back to 1.07b and sdk 2.1, for example, and use previous oclhc version.

Ok tnx, i will try to roll back . . . . .
