The motherboard comes with three Double Data Rate (DDR) Dual Inline Memory
Module (DIMM) sockets. These sockets support up to 2GB system memory using
184-pin unbuffered non-ECC PC3200/2700/2100/1600 DDR DIMMs. The following
figure illustrates the location of the DDR DIMM sockets.

1.9.1 Memory configurations
You may install any DDR DIMMs with 64MB, 128MB, 256MB, 512MB, and 1GB
densities into the DIMM sockets.
1. DDR DIMM sockets 2 and 3 share the same rows, so if you install a
double-sided DIMM into DIMM2 socket, you must leave DIMM3 socket
empty.
2. You may install single-sided DIMMs into DIMM2 and DIMM3 sockets at the
same time but neither one can be 16-bit DDR module.
3. Double-sided 16-bit DDR DIMMs are not supported on this motherboard.
Use only the following combinations to install DDR DIMMs. Otherwise, the
system may not boot up.

If you wish to use a PC3200 (400MHz) DDR module, you need to install a CPU
with 800MHz FSB.
