2-2 Memory Installation

How to tackle the memory Modules:
• Make sure to unplug your power supply before adding or removing
memory module.
• Pay attention to the orientation of the DIMM slots.

2-2.1 To Install DDR SDRAM Module

• To enable Dual-channel memory function, users should insert totally
identical (size and frequency) DDR module pair into the bank-pair. In
this series, DIMM1 and DIMM3 is a pair, and DIMM2 and DIMM4 is
another.
• DDR DIMM slot has 184 pins and one notch. Insert a DDR SDRAM
vertically into the 184-pin slot with the notch-to-rib matching.

2-2.2 Dual Channel Memory Features

The Dual Channel DDR SDRAM installation is quite different from the
Single channel installation.
• 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 4GB unbuffered Dual-channel DDR 400/
333/266 SDRAM, with 4 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 6.4GB/s with DDR400, 5.4GB/s with DDR333 and 4.2GB/s with
DDR266.
