Memory Configurations
You may install 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.
•
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 DDR400 Qualified Vendors List
on the next page for details.
• 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.
• Due to CPU limitation, DIMM modules with 128 Mb memory chips or
double-sided x16 memory chips are not supported in this
motherboard.
