Memory; Introduction To Ddr Sdram - MSI KT4A-V User 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 PC3200/DDR400, PC2700/DDR333, PC2100/
DDR266 or PC1600/DDR200 modules on the DDR DIMM slots. Please note
that the mainboard supports only one DDR400 DIMM.

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.
