Installing Memory Modules

This motherboard accommodates four memory modules, which
are two 184-pin 2.5V DIMM3-4 sockets (Dual Inline Memory
Module) for unbuffered DDR 400/333 memory modules (Double
Data Rate SDRAM) and the other two 240-pin 1.8V DIMM1-2
sockets (Dual Inline Memory Module) for unbuffered DDR2 533/
400 memory modules (Double Data Rate SDRAM). DDR
SDRAM is a type of SDRAM that supports data transfers on
both edges of each clock cycle (the rising and falling edges),
effectively doubling the memory chip's data throughput. You must
install at least one module in any of the four slots. Each module
can be installed with 256 MB to 1 GB of memory; total memory
capacity is 2 GB.
Note1: Please be noted you can NOT use DIMM1-2(DDR2 533/
400) and DIMM3-4(DDR 400/333) simultaneously. Only use
either DDR2(533/400) or DDR(400/333) memory modules!
Note2: Do not remove any memory module from its antistatic
packaging until you are ready to install it on the motherboard.
Handle the modules only by their edges. Do not touch the
components or metal parts. Always wear a grounding strap
when you handle the modules.
