System memory
2.5.1 Overview
The motherboard comes with four Double Data Rate (DDR) Dual Inline
Memory Module (DIMM) sockets. These sockets support up to 3GB
system memory using 184-pin PC3200/PC2700/PC2100/PC1600
unbuffered ECC DDR DIMMs and allow up to 5.33 GB/s data transfer rate.
The following figure illustrates the location of the DDR DIMM sockets.
Notes on DDR technology
The DDR SDRAM technology evolved from the mainstream PC66, PC100,
PC133 memory known as Single Data Rate (SDR) SDRAM. DDR memory
however, has the ability to perform two data operations in one clock cycle,
thus providing twice the throughput of SDR memory.
A DDR DIMM has the same physical dimensions as an SDR DIMM, but it
has a 184-pin footprint compared to the 168-pin of the SDR DIMM. Also, a
DDR DIMM is single notched while an SDR DIMM is double notched.
Therefore, a DDR DIMM is not backward compatible with SDR, and should
be installed only in a socket specially designed for DDR DIMMs.
