That's a Compute 2.0 gpu and I believe that ccminer with fresh algo only supports cards with Compute 3.0 or higher. I might be wrong as there might be a ccminer compiled for Compute 2.0 somewhere out there.
Given that it actually does some work (stratum detected new block, kh/s display, etc.), that does not seem to be the problem. Surely if the problem was compute version, it would crash with something like "illegal instruction".
