Memory Subsystem
Architecture

Each Intel® Xeon® E5-2600v3 family processor socket contains four memory channels per
installed processor with two DIMMs per channel for a total of eight (8) DIMMs or a grand total of
sixteen (16) 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 1.2V.
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.
To realize the performance memory capabilities listed in this document, HP SmartMemory is required.
There are four (4) channels per processor; eight (8) channels per server.
There are three (3) DIMM slots for each memory channel; twenty-four (24) total slots.
Memory channels1 and 3 consists of the three (3) DIMMs that are furthest from the processor.
Memory channel 2 and 4 consists of the three (3) DIMMs that are closest to the processor.
