3.5 Supporting and Populating the Memory Module (DIMM)
The server board is capable of supporting 16 DIMMs (8 DIMMs per processor). However, to support the
processors in this system with a TDP of 200W or 205W, larger CPU heat sinks are used to support the
increased thermals of these processors. As a result, two (2) DIMM connectors from each processor are
rendered unusable due to Processor Heat Sink Module (PHM) interference.
Components Required:
DIMM connectors identified in white below are supported in the configurations listed below. Black DIMM
connectors are not supported.

3.5.1 General Memory Population Rules:
Each compute node has support for the following memory configuration modes:
 Independent Memory Mode (Default Normal Mode)
 Memory Mirroring Mode
 Memory Rank Sparing Mode
3.5.2 DIMM Installation Order
DIMMs must be installed in a certain order according to the memory mode configuration of the nodes.
By default, the compute node supports the Independent Memory Mode when DIMMs are installed in the
following order: 6, 14, 3, 11, 7, 15, 2, 10, 8, 16, 1, and 9.
Memory Mirroring and Memory Rank Sparing modes are supported only when the compute node has the
proper memory configuration installed and one of the memory modes is enabled in BIOS Setup.
In order to support a Memory Mirroring Mode, identical DIMMs must be installed in the following population
sets: (6, 7, 8), (14, 15, 16), (1, 2, 3), (9, 10, 11).
In order to support a Memory Rank Sparing Mode, DIMMs must be installed in the following population
order: 6, 14, 3, 11, 7, 15, 2, 10, 8, 16, 1, and 9.
When DIMMS are installed or removed, the node configuration information changes. The system indicates
this change by displaying a message that the memory configuration has changed once the node is restarted.
