1.7.1 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:
1.7.2 Memory Configurations
You may install 64MB, 128MB, 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.
• 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 DDR400 Qualified Vendors List
on Page 1-15 for details.
• If you installed four 1 GB 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.
• Due to CPU limitation, install on Channel B slots for a single-channel
memory configuration.
