    radeon rx480 armor, openCL and ubuntu


      So I purchased a few Radeon RX480 armors so I could use them for openCL on ubuntu 16.04 . I went through and downloaded the correct amdgpu-pro driver for ubuntu, and the AMD openCL SDK. It appears that the cards themselves are using the amdgpu drivers but show nothing when I check clinfo. All the installers finished and exited correctly and there's no error other than the fact that the devices don't show.

      Is this a known issue that the Radeon RX480 armors don't work with openCL on linux? I should mention that I spent maybe 6 hours trying different versions of drivers, AMD openCL sdk and reinstalling the operating system (ubuntu 16.04.1) .
