The two DDR DIMM sockets support 2.5Volt (power level) unbuffered/registered Double Data Rate Synchronous Dynamic Random Access Memory (DDR SDRAM) of 64MB, 128MB, 256MB, 512MB, and 1GB to form a memory size between 64MB to 2GB. One side (with memory chips) of the DIMM takes up one row on the motherboard.

DDR DIMMs support non-ECC modules that are available in both registered (typically used in servers) and unbuffered (typically used in PCs) versions.

NOTE: The DDR memory bus runs at the same frequency as the CPU front side bus.
