2.4System memory

The motherboard comes with four Double Data Rate (DDR) Dual Inline Memory Module (DIMM) sockets. These sockets support up to 4GB system memory using 184-pin unbuffered ECC or non-ECC PC2700/ PC2100 DDR DIMMs, and allow up to 5.33GB/s data transfer rate.

The following figure illustrates the location of the DDR DIMM sockets.
