8-6 Dell PowerEdge 2450 Systems Installation and Troubleshooting Guide
The system is upgradable to 2 GB by installing combinations of 64-, 128- 256-, and
512-MB registered DIMMs. You can purchase memory upgrade kits from Dell as
needed.
NOTE: The DIMMs must be PC-133 compliant.
Starting with the socket nearest to the system board's front edge, the DIMM sockets
are labeled “DIMM_A” through “DIMM_D” (see Figure 8-4). When you install
DIMMs, follow these guidelines:
Install a DIMM in socket DIMM_A before socket DIMM_B, socket DIMM_B
before socket DIMM_C, and so on.
If you install different sizes of DIMMs, install them in order of descending capac-
ity, beginning with the highest-capacity DIMM in socket DIMM_A.
You do not need to install DIMMs in pairs.
