Memory; Introduction To Ddr Sdram - MSI K7N2M Manual

The mainboard provides:
2 DDR SDRAM DIMMs to support Dual Channel DDR266/333,
max. 2GB (nForce2 IGP only)
2 DDR SDRAM DIMMs to support Single Channel DDR266/333/
400, max. 2GB (nForce2 400 only)
You can install DDR400 (nForce2 400 only)/333/266/200 modules on
the DDR DIMM slots (DIMM 1~2).

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.
