I figured out how to resolve this issue.
As it turns out many MSI Laptops (gaming/creator) have a "OpenCL and OpenGL Compatibility Pack" installed, which makes more OpenCL GPUs (@12Hz) available to the system but these are not compatible with AIDA GPGPU benchmark or Stability test.
Uninstalling this "OpenCL and OpenGL Compatibility Pack" solve the problem. See attached picture.
It's also known as "Microsoft.D3DMappingLayers_8wekyb3d8bbwe".
