Installing System Components
Memory
The four memory module connectors on the system board can accommodate
from 512 MB to 8 GB of 667-MHz and 800-MHz unbuffered ECC DDR II
single or dual-rank memory modules. See Figure 6-2 for the location of the
four memory module connectors.
NOTE:
When installing memory, take care to install it in the proper slots according
to the configuration guidelines in Table 3-2. Installing memory in the wrong slots will
significantly reduce system performance. See Figure 6-2 for slot locations.
Memory Module Upgrade Kits
The system is upgradable to 8 GB by installing combinations of 512-MB,
1-GB, and 2-GB 667-MHz or 800-MHz unbuffered ECC DDR II single or
dual-rank memory modules. You can purchase memory upgrade kits from
Dell.
Memory Module Installation Guidelines
• If only one memory module is installed, it must be installed in connector
DIMM_1A.
• If only one memory module is installed in connector DIMM_1A, its
capacity can be 512 MB, 1 GB, or 2 GB.
• If more than one memory module is installed, the memory modules must
be installed in pairs of matched memory size, speed, and technology.
• Memory modules must be installed in ordered pairs in connectors
DIMM_1A and DIMM_1B, and then DIMM_2A and DIMM_2B.
• Installing three memory modules is not supported.
NOTICE:
If you remove your original memory modules from the system during a
memory upgrade, keep them separate from any new memory modules that you may
have, even if you purchased the new memory modules from Dell. Use only
unbuffered ECC DDR II memory modules.
Table 3-2 illustrates memory configuration guidelines. It is important to
follow the slot installation configurations shown here to achieve maximum
memory performance.
