Covert mining cards to be used as normal cards for 3D Rendering.

Recently purchased RTX Sapphire 470 AMD crypto mining GPUS used for crypto mining. Trying to convert them to be used for 3D Rendering in use Blender cycles.

Cards are spinning and everything on the techical side is all done, but we are having issues with bios, flushed bios but still it does not work when trying to render in cycles it simply blue screens.

Anyone familier with anything related to this would be of great help.
