For UDIMMs, DIMM connectors 3, 6, 7, and 10 for microprocessor 1 and DIMM
connectors 15, 18, 19, and 22 for microprocessor 2 are not used.
Notes:
1. You can install DIMMs for microprocessor 2 as soon as you install
microprocessor 2; you do not have to wait until all of the DIMM slots for
microprocessor 1 are filled.
2. DIMM slots 13-24 are reserved for microprocessor 2; thus, DIMM slots 13-24
are enabled when microprocessor 2 is installed.
The following illustration shows the location of the DIMM connectors on the system
board.

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
non-mirroring mode, all three channels on the memory interface for each
microprocessor can be populated in any order and have no matching requirements.
Important: If you have configured the server to use memory mirroring, do not use
the order in Table 8; go to “Memory mirrored channel” on page 111 and use the
installation order shown there.
