System memory

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.

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.

x16 Double-sided DDR DIMMs (16-bit memory chips) are not supported on
this motherboard.

You may install single-sided DIMMs into DIMM2 and DIMM3 sockets at the
same time but neither one can be x16 DDR module.

Use only the following combinations to install DDR DIMMs. Otherwise, the
system may not boot up.

It is recommended to use the DIMM slots sequentially according to the
following: DIMM slot 1->DIMM slot 2 -> DIMM slot 3.

If you wish to use a PC3200 (400MHz) DDR module, you need to install a CPU
with 800MHz FSB. Without an 800MHz FSB CPU, the DDR module can only
run at 333MHz or lower frequency.
