3.3.2 Memory Configurations
You may install 1GB, 2GB, and 4GB unbuffered ECC or non-ECC DDR3 SO-DIMMs into
the SO-DIMM sockets using the memory configurations in this section.
Important

IF you installed four 1GB memory modules, the system may detect
less than 3GB of total memory because of address space allocation
for other critical functions. This limitation applies to Windows XP
32-bit version operating system since it does not support PAE
(Physical Address Extension) mode.

IF you install Windows XP 32-bit version operating system, we
recommend that you install less than 3GB of total memory.

For dual channel configuration, the total size of memory module(s)
installed per channel must be the same for better performance
(DIMMA1=DIMMB1).

Always install SO-DIMMs with the same CAS latency. For optimum
compatibility, it is recommended that you obtain memory modules
from the same vendor.

Due to CPU limitation, SO-DIMM modules with 128Mb memory chips
or double-sided x16 memory chips are not supported in this
motherboard.
