v The maximum operating speed of the server is determined by the slowest
DIMM installed in the server.
v A minimum of one DIMM must be installed for each microprocessor. For
example, you must install a minimum of two DIMMs if the server has two
microprocessors installed. That is, one for microprocessor 1 and one for
microprocessor 2.
v The server comes with a minimum of one DIMM installed in slot 1. When you
install additional DIMMs, install them in the order shown in the information in
the following tables to optimize system performance.
v The server supports independent mode, spare channel mode, and mirroring
mode.
v Independent mode: When you use the independent mode, install DIMMs as
indicated in the following tables.
The following table lists the DIMM installation sequence for non-mirroring
mode when one or two microprocessors is installed in the server:
Table 5. DIMM population sequence (independent mode)
Number of installed
microprocessors DIMM connector population sequence
1 1,3,5,2,4,6
2 1, 7, 3, 9, 5, 11, 2, 8, 4, 10, 6, 12
v Spare channel mode: When you use the memory mirroring feature, consider the
following information:
In spare channel mode, one rank is a spare of the other ranks on the same
channel. The spare rank is held in reserve and is not available as system
memory. The spare rank must have identical or larger memory capacity than
all the other ranks (sparing source ranks) on the same channel. After sparing,
the sparing source rank will be lost.
DIMMs must be installed in sets of three. The DIMMs in each set must be the
same size and type.
The following table lists the DIMM installation sequence for rank sparing
mode when one or two microprocessors is installed in the server:
