DIMM installation sequence

Depending on the server model, the server may come with a minimum of one 2 GB or 4 GB DIMM installed in slot 3.

When you install additional DIMMs, install them in the order shown in the following table to optimize system performance. In non-mirroring mode, all three channels on the memory interface for each microprocessor can be populated in any order and have no matching requirements.

Table 1. Non-mirroring (normal) mode DIMM installation sequence
Installed microprocessor DIMM connector population sequence
Microprocessor socket 1 3, 6, 9, 2, 5, 8, 1, 4, 7
Microprocessor socket 2 12, 15, 18, 11, 14, 17, 10, 13, 16
