2-4 Install Memory
The motherboards provide one 240-pin DUAL INLINE MEMORY MODULES (DIMM)
sites for memory expansion available from minimum memory size of 64MB to maximum
memory size of 1.0GB DDR2 SDRAM.
Valid Memory Configurations
Bank 240 -Pin DIMM PCS Total Memory
Bank 0, 1 (DDR1) DDR2 533/DDR2 400
DDR2 SDRAM Module
X1 64MB
∼1.0GB
Total System Memory (Max. 1.0GB) 1 64MB
∼1.0GB
Generally, installing DDR SDRAM modules to your motherboard is very easy, you can refer
to figure 2-4 to see what a 240-Pin DDR2 400/DDR2 533 DDR2 SDRAM module looks
like.

NOTE! When you install DIMM module fully into the DIMM socket the eject tab should be
locked into the DIMM module very firmly and fit into its indention on both sides.
WARNING! For the DDR SDRAM CLOCK is set at 133MHz, use only DDR266-compliant DDR
Modules. When this motherboard operate at 133MHz, most system will not even
boot if non-compliant modules are used because of the strict timing issues, if your
SDR Modules are not DDR266-compliant, set the DDR SDRAM clock to 100MHz
to ensure system stability.
