Help needed with GPU not being recognized by miner

Haven't been mining since script days. I setup a new rig to test a gihabyte rx480 in windows7. Everything goes well. The latest driver is installed and so is the latest SDK with amd opencl 2.0. The driver shows fine on the device manager. But can't have nheqminer .04a or genoil 6.0 to recognize the GPU. Have I missed a step along the way? Tia
