I am using this graphic card, but I don't know how to render via this GPU? Is it possible? And how to do it because I don't see in options to choose my GPU. Tnx
First check that your gpu drivers are up to date. The opencl libraries provide the list of available hardware that blender uses to offer available GPU options.
While I'm not sure if the devs are interested in bug reports relating to opencl, they generally appreciate reports of what hardware works and what doesn't.
