Hmm
Strange i put from catalyst 15.3 beta dll's to new Wolf sgminer folder:
amd_opencl32, amd_opencl64, amdocl, amdocl64.dll, and on 290/290x sgminer crash on start.
But on 280x works well when catalyst 14.4 is installed, and these dll's from 15.3 are in sgminer folder.
I reinstall catalyst 14.4 to 15.3 beta on 290/290x and sgminer works, don't crash.
But i like 14.4 because i can change clock speeds on 290/290x in msi afterburner.
You know what may be wrong Wolf?
