Memory Configurations
You may install 256 MB, 512 MB, 1 GB, 2 GB, or 4 GB registered 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.

•
When using one DDR DIMM module, install into DIMM_A1 slot only.
•
When using two DDR DIMM modules, install into DIMM_A1 and
DIMM_A2 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.
• 4 GB DDR400 registered ECC DIMMs operate in 2000SER, 2003SER,
or 64-bit operating systems.
