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

Memory configurations
You may install 512 MB, 1 GB and 2 GB unbuffered non-ECC DDR2 DIMMs into
the DIMM sockets.

Always install DIMMs with the same CAS latency. For optimum compatibility,
it is recommended that you obtain memory modules from the same vendor.
When installing total memory of 4GB capacity or more, Windows 32-bit
operation system may only recognize less than 3GB. Hence, a total
installed memory of less than 3GB is recommended.
