Memory; Introduction To Ddr Sdram; Dimm Module Combination - MSI K8N Diamond User Manual

The mainboard provides 4 slots for 184-pin DDR SDRAM DIMM (Double In-Line
Memory Module) modules and supports the memory size up to 4GB. You can install
DDR266/ 333/400 modules on the DDR DIMM slots (DDR 1~4).

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 modules rather than 168-pin DIMM
modules used by SDR SDRAM. High memory bandwidth makes DDR an ideal solution
for high performance PC, workstations and servers.

DIMM Module Combination

Install at least one DIMM module on the slots. Each DIMM slot supports up to a
maximum size of 1GB. Users can install either single- or double-sided modules to
meet their own needs. Please note that each DIM M can work respectively for
single-channel DDR, but there are some rules while using dual-channel
DDR (Please refer to the suggested DDR population table below). Users may install
memory modules of different type and density on different-channel DDR DIMMs.
However, the same type and density memory modules are necessary while
using dual-channel DDR, or instability may happen. Please refer to the following table
for detailed dual-channel DDR. Other combination not listed below will function as
single-channel DDR.
