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