A system and method for providing an adapter for re-use of legacy DIMMS in a fully buffered memory environment. The system includes a memory adapter card having two rows of contacts along a leading edge of a length of the card. The rows of contacts are adapted to be inserted into a socket that is connected to a daisy chain high-speed memory bus via a packetized multi-transfer interface. The memory adapter card also includes a socket installed on the trailing edge of the card. In addition, the memory adapter card includes a hub device for converting the packetized multi-transfer interface into a parallel interface having timings and interface levels that are operable with a memory module having a parallel interface that is inserted into the socket. In addition, the hub device converts the packetized multi-transfer interface into a parallel interface having timings and interface levels that are operable with a memory module having a parallel interface that is inserted into the socket. The hub device also converts the parallel interface into the packetized multi-transfer interface.
