I have a dual xeon workstation with dual HD 6970s in crossfire. I had these in my old system and I remember fiddling with registries and drivers for about a week to get OpenCL working. Now in this workstation, I have forgotten what I did. I have the latest Crimson drivers installed and the APP SDK 2.7, and 2.9. Please let me know what I need to do in order to get the OpenCL drivers functioning again. GPU-Z and Geeks 3D Caps Viewer screenshots are down below.
