DIMMconnectors 1 and 2 are channel A, and DIMM connectors 3 and 4 are channel B.v If DIMM connectors 1 and 3 (or 2 and 4) are filled with the same technology andsize of memory, the system operates in dual channel mode.v Use 2.5 V, 184-pin, double data rate synchronous dynamic random accessmemory (DDR SDRAM).v Use 128 MB, 256 MB, 512 MB or 1.0 GB DIMMs in any combination.v DIMMs are 38.1 mm (1.5 inches) in height.Note: Only DDR SDRAM DIMMs can be used.36 User Guide
