DIMM Sockets Location
The motherboard comes with two 200-pin Double Data Rate 2 (DDR2) SODIMM sockets.
A DDR2 module has the same physical dimensions as a DDR DIMM but has a 200-pin
footprint compared to the 184-pin DDR DIMM. DDR2 DIMMs are notched differently to
prevent installation on a DDR DIMM socket. The following figure illustrates the location of
the sockets:

Memory Configurations
You can install 256MB, 512MB, 1GB and 2GB DDR2 SDRAM DIMMs into the SODIMM
sockets using the memory configurations in this section.
Installing DDR2 DIMM other than the recommended
configurations may cause memory sizing error or system boot
failure. Use any of the recommended configurations.
Due to chipset graphic resource allocation, the system may
detect less than 2 GB system memory when you installed one 2
GB DDR2 memory modules.
This motherboard does not support memory modules FSB less
than 667MHz.Make sure that the memory frequency matches the
CPU FSB (Front Side Bus). Refer to the Memory frequency/CPU
FSB synchronization table.
