2.79 OpenCL wont work

For some strange reason I can’t get Blender to recognize my amd gpu or even use OpenCL. I’ve tried the “set CYCLES_OPENCL_TEST=all” method and tried changing my feature set to experimental. All done on a fresh install of 2.79 default prefs and everything. It still shows “none” for my compute devices and no OpenCL button anywhere. Any idea’s why this is happening?

From the blender manual https://docs.blender.org/manual/en/dev/render/cycles/gpu_rendering.html#opencl

OpenCL

OpenCL is supported for GPU rendering with AMD graphics cards. We only support graphics cards with GCN architecture 2.0 and above). To make sure your GPU is supported checkout this Wikipedia page.

From the link your graphics card shows up as:

Therefore may not be compatible for openCL rendering

Ah thank you for that.
