DDR4 memory population guidelines
For detailed memory configuration rules and guidelines, please use the Online DDR4 Memory Configuration Tool:
www.hp.com/go/DDR4memory-configurator
Each Intel® Xeon® E5-2600 family processor socket contains four memory channels that support two DIMMs each for a total of
eight (8) DIMM per installed processor or a grand total of sixteen (16) DIMMs for the server. Up to 16GB capacity DIMMs are
supported for 256GB of memory (16 DIMM slots x 16GB per DIMM).
Memory Population Rules and Guidelines:

White DIMM slots denote the first slot of a channel. For 1 DPC (DIMM per channel) populate white slots only.

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
to load the channels similarly whenever possible.

Populate DIMMs from heaviest load (quad-rank) to lightest load (single-rank) within a channel.

Heaviest load (DIMM with most ranks) within a channel goes furthest from the processor.

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.

HP memory from previous generation servers is not qualified on the ProLiant XL730f Gen9

Server. Certain HP SmartMemory features such as memory authentication and enhanced performance may not be
supported.

To realize the performance memory capabilities listed in this document, HP SmartMemory is required. For additional
information, please see the HP SmartMemory QuickSpecs at:
