Memory Subsystem
Architecture

Each Intel® Xeon® E5-2600v3 family processor socket contains four memory channels per
installed processor with three DIMMs per channel for a total of twelve (12) DIMMs or a grand total
of twenty-four (24) DIMMs for the server.

Memory Population
guidelines

General Memory Population Rules and Guidelines:

Install DIMMs only if the corresponding processor is installed.
If only one processor is installed in a two processor system, only half of the DIMM slots are
available.
To maximize performance, it is recommended to balance the total memory capacity between
all installed processors and load the channels similarly whenever possible.
When two processors are installed, balance the DIMMs across the two processors.
White DIMM slots denote the first slot to be populated in a channel.
Place the DIMMs with the highest number of ranks in the white slot when mixing DIMMs of
different ranks on the same channel.
Do not mix RDIMMs or LRDIMMs.
Quad rank RDIMMs are not supported in HP ProLiant ML350 Gen9 servers.
Quad rank LRDIMMs are capable of up to three DIMMs per channel.
RDIMMs operating at either 1.35V or 1.5V may be mixed in any order, but the system will
power them at the higher voltage.
DIMMs of different speeds may be mixed in any order; the server will select a common
optimal speed.
The maximum memory speed is a function of the memory type, memory configuration, and
processor model.
The maximum memory capacity is a function of the memory type and number of installed
processors.
