cp manager as in device manager? If it shows up in device manager but not being found as opencl device try right clicking under manager and uninstalling the drivers and then reinstalling in device manager by browsing for the amd folder in programs file. You might need to uninstall and then reinstall drivers via the amd ccc. Reboot and then uninstall drivers in device manager. Although I don't know in w10 if it will just reinstall them right away after idling. I would just reinstall windows though. Disable windows automatic update in group policy right after installing windows, and then install 15.12.
I can see
