1.7.1
Overview
The motherboard comes with two 240-pin Double Data Rate 2 (DDR2) and
two 184-pin DDR Dual Inline Memory Modules (DIMM) sockets.
DDR2 DIMMS are notched differently to prevent misplacement in DDR DIMM
sockets.
The following figure illustrates the location of the sockets:

Memory Configurations
You may install 256 MB, 512 MB and 1 GB unbuffered non-ECC DDR/DDR2
DIMMs into the DIMM sockets using the memory configurations in this
section.
To prevent damage to the motherboard,
do not use DDR
and
DDR2
memory simultan
e
ously.
Due to chipset resource allocation, the system may detect less than
2 GB system memory when you installed two 1 GB DDR2 or DDR
memory modules.
