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.
