1.5.2 Memory Configurations
You may install 1 GB, 2 GB , and 4 GB unbuffered ECC or non-ECC DDR3 DIMMs into the
DIMM sockets using the memory configurations in this section.

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

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 +DIMMA2=DIMMB1+DIMMB2).
