AFAIK, it's not compatible with Sapphire HD7950 Mac Edition EFI. That EFI is made for Tahiti GPUs.

Tahiti is a GCN1.0 GPU, while Tonga is a GCN3.0 GPU, released two years later.

Thanks alex this new information from great macrumors member, thanks, I believe that all R200 series are same Architecture, & read R285 was flashed, may be using another Method.
