DDR DIMM Slots

(DDR 1~4, from left to right)

Channel A: DIMM1 & DIMM2

Channel B: DIMM3 & DIMM4

The mainboard provides 4 slots for 184-pin, 2.5V DDR DIMM with 8

memory banks. You can install DDR266/DDR333/DDR400 SDRAM modules on

the DDR DIMM slots (DIMM 1~4). 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 modules

rather than 168-pin DIMM modules used by SDR SDRAM. Please note that

the DDR SDRAM does not support ECC (error correcting code) and registered

DIMM.

DDR Population Rules

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 DIMM 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 on p.

2-8).Users may install memory modules of different type and density on different-
