2.4.1 2.4.1 2.4.1 2.4.1 2.4.1 Overview Overview Overview Overview Overview
The motherboard comes with four 184-pin Double Data Rate (DDR) Dual
Inline Memory Modules (DIMM) sockets.
The following figure illustrates the location of the sockets:

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.
• Always install DIMMs with the same CAS latency. For optimum
compatibility, it is recommended that you obtain memory modules
from the same vendor. Refer to the memory Qualified Vendors List
on the next page for details.
• Due to CPU limitation, DIMM modules with 128 Mb memory chips or
double-sided x16 memory chips are not supported in this motherboard.
