Memory; Introduction To Ddr Sdram - MSI MS-6585 Technical Manual

The mainboard provides 3 slots for 184-pin DDR SDRAM DIMM (Double
In-Line Memory Module) modules and supports the memory size up to 3GB.
You can install PC2700/DDR333 or PC2100/DDR266 modules on the DDR DIMM
slots (DIMM 1~3). To operate properly, at least one DIMM module must be
installed.

Introduction to DDR SDRAM

DDR (Double Data Rate) SDRAM is similar to conventional SDRAM,
but doubles the rate by transferring data twice per cycle. It uses 2.5 volts as
opposed to 3.3 volts used in SDR SDRAM, and requires 184-pin DIMM mod-
ules rather than 168-pin DIMM modules used by SDR SDRAM. High memory
bandwidth makes DDR an ideal solution for high performance PC, worksta-
tions and servers.
