2.4.2 Memory Configurations
You may install 64 MB, 128 MB, 256 MB, 512 MB, or 1 GB unbuffered ECC
DDR DIMMs into the DIMM sockets using the memory configurations in this
section.
• For dual-channel configuration, the total size of memory module(s)
installed per channel must be the same for better performance
(DIMM_A2=DIMM_B2).
• Due to chipset resource allocation, the system may detect less than
4 GB of system memory when you installed four 1 GB DDR memory
modules.
• When using single channel DDR DIMM modules, install into DIMM_A1
or DIMM_A2 slot only.
• Always install DIMMs with the same CAS latency. For optimum
compatibility, we recommend that you obtain memory modules from
the same vendor. Refer to the DDR400 Qualified Vendors List at the
ASUS web site.
