RAM management, in principle, cannot work as an overlay. You're trying to use an overlay where it basically can't work. Have you seen on a regular PC that someone on a running system connected or disconnected the DDR memory strips and the system automatically changed the RAM? The PnP principle (dynamic overlay/parameter change) works only with equipment that can be dynamically reconfigured (load or unload drivers or change their settings, if they support it).
