Lack of the 6 Pin connector could mean the GPU is attempting to pull more power though the MOBO than the manufacturer allows ? Possibly that's why it's not on the approved list ? "Looks to be the same memory" isn't the same as the Exact Model Number. As @TrashZone posted, AMD can be "really finicky". Anyone building a new Rizen Rig should pay careful attention to what's on their particular MOBO Model's list of Compatible Devices.
