•
To utilize all memory channels and provide best performance when one processor is installed, install
regular DIMMs in sequential alphabetic order: A, B, C, D, E, F, and so forth.
•
When two processors are installed, install the regular DIMMs in sequential alphabetic order
balanced between the two processors: P1-A, P2-A, P1-B, P2-B, P1-C, P2-C, and so forth. If
installing NVDIMM-Ns in an unbalanced configuration, see the
HPE 8GB NVDIMM User Guide on
the Hewlett Packard Enterprise Information Library ( http://www.hpe.com/info/NVDIMM-docs ).
•
To achieve the best performance, install only two DIMMs per channel in servers with three DIMM
slots per channel. When three DIMMs per channel are populated, the speed reduces from 2400
MT/s or 2133 MT/s to 1600 MT/s.
The operating frequency is reduced to 1867 MT/s if the following are true:
o
If any channel in the system is populated with two DIMMs per channel and at least one of them is
NVDIMM.
o
If no channel in the system is configured with three DIMMs per channel.
o
If a channel in the system configured with two DIMMs per channel is populated with all regular
DIMMs, an NVDIMM-N installed in a one DIMM per channel configuration runs at 2133 MT/s.

Advanced ECC population guidelines
For Advanced ECC mode configurations, observe the following guidelines:
•
Observe the general DIMM slot population guidelines.
•
DIMMs may be installed individually.
Online spare population guidelines
For Online Spare memory mode configurations, observe the following guidelines:
•
Observe the general DIMM slot population guidelines.
•
Each channel must have a valid online spare configuration.
•
Each channel can have a different valid online spare configuration.
•
Each populated channel must have a spare rank. A single dual-rank DIMM is not a valid
configuration.
Population order
For memory configurations with a single processor or multiple processors, DIMMs must be populated
sequentially in alphabetical order (A through L).
After installing the DIMMs, use the BIOS/Platform Configuration (RBSU) in the UEFI System Utilities to
configure supported AMP modes.
Mirrored Memory population guidelines
For Mirrored Memory mode configurations, observe the following guidelines:
•
Observe the general DIMM slot population guidelines.
•
Install DIMMs in either channel 1 and channel 2, or channel 3 and channel 4. Installed DIMMs must
be identical in terms of size and organization.
•
In multi-processor configurations, each processor must have a valid Mirrored Memory configuration.
