2-2 Memory Installation
How to tackle 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
into a slot improperly will damage the memory module and slot itself.
• Make sure you have the right type of memory module for your
mainboard.
• 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 3GB unbuffered Dual Channel DDR 400/
333/266 SDRAM, with 3 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 couple of DDR400, 5.4GB/s with couple of DDR333
and 4.2GB/s with couple of DDR266.
