    Totally the wrong forum for this question - Microsoft Home Server!!!

    Wikipedia is your friend (please contribute to their current fund raising drive):

    AMD confirmed that there is an upgrade path from Socket AM2+ to AM3:

    • AM3 processors work on AM2+ motherboards due to the presence of both the DDR2 and DDR3 memory controllers on the processor
    • AM2+ processors do not work on AM3 motherboards due to the processor's lack of a DDR3 memory controller

    The pin configuration of the AM2+ socket (940 pins)<sup class="reference" id="cite_ref-thdwr_2-0">[2]</sup> is mechanically different from the AM3 socket (941 pins)<sup class="reference" id="cite_ref-thdwr_2-1">[2]</sup>

    Hybrid motherboards

    An A790GXH motherboard that can support AM2, AM2+ and AM3 socket CPUs

    Some motherboard manufacturers (i.e. ASRock, Jetway, and MSI) have released hybrid motherboards that are equipped with an AM2+ socket and both DDR2 and DDR3 memory slots. These boards permit the use of AM2/AM2+ processors with DDR2 RAM, or AM3 processors with either DDR2 or DDR3 RAM.
