2-3 Memory Installation

How to tackle with the memory Modules:
• Make sure to unplug your Power Supply before adding or removing
memory module. Failure to do so may cause severe damage to both your
mainboard and the memory module.
• Pay attention to the orientation of the DIMM slots. Forcing a DIMM in a
socket improperly will damage the memory module and slot.
• Make sure you have the right type of memory module for your mainboard.

2-3.1 Dual Channel Memory Features

• Dual Channel Memory Configuration is formed by couple of identical DDR
SDRAMs.
• Dual Channel memory configuration provides higher performance than
Single Channel configurations.
• Matched DIMMs need to have identical density, DRAM technology, DRAM
bus width, and equal number of memory banks.
• This series supports up to 2GB unbuffered Dual Channel DDR 333/266
SDRAM, with 2 DDR DIMM slots on board. Do not insert other type of
modules into these slots.
• The dual memory controller can double the DDR memory bandwidth up to
5.4GB/s with couple of DDR333 and 4.2GB/s with couple of DDR266.

2-3.2 To Install DDR SDRAM Module

• To enable Dual-channel memory function, users should insert totally iden-
tical (size and frequency) DDR module pair into the bank-pair.
• DDR DIMM slot has 184 pins and one notch. Insert a DDR SDRAM verti-
cally into the 184-pin slot with the notch-to-rib matching.
