amd 280x

that's a known problem with amd and  msi afterburner (might be clear off after a few reset, don't remember the procedure though)

You may use MSI afteterburner to set the memory freuquency.

no change also with afterburner, setting up 1500 but is stuck at 1600(default).

You may use AMD uninstaller to clean up the drivers and then install again.
