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:

•
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).
