12GB DDR3 1066MHz ECC Mac Pro KIT (3X4GB)

To use this DDR3 memory, your system must have both a 240-pin DIMM slot and a chipset that supports DDR3 memory. A DDR3 DIMM will not fit into DDR2 or DDR memory sockets. (Information about which memory technology your system uses is included in the memory configurator or memory selector tool.)
