Overview

The motherboard comes with four Double Data Rate 2 (DDR2) Dual Inline
Memory Modules (DIMM) sockets.
A DDR2 module has the same physical dimensions as a DDR DIMM but has a
240-pin footprint compared to the 184-pin DDR DIMM. DDR2 DIMMs are notched
differently to prevent installation on a DDR DIMM socket.
The figure illustrates the location of the DDR2 DIMM sockets:

Memory Configurations
You may install 64 MB, 128 MB, 256 MB, 512 MB and 1 GB unbuffered ECC or
non-ECC DDR 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 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 (DIMM_A1
+DIMM_A2=DIMM_B1+DIMM_B2).
When using one DDR DIMM module, install into DIMM_B1 slot only.
When using two DDR DIMM modules, install into DIMM_A1 and DIMM_B1
slots only.
