5.3.1.4 DIMM Installation Rules
Observe the following when configuring DDR4 memory modules:
⚫
Install memory modules only when corresponding processors are installed.
⚫
Do not install LRDIMMs and RDIMMs in the same server.
⚫
Install filler memory modules in vacant slots.
Observe the following when configuring DDR4 memory modules in specific operating mode:
⚫
Memory sparing mode
−
Comply with the general installation guidelines.
−
Each memory channel must have a valid online spare configuration.
−
The channels can have different online spare configurations.
−
Each populated channel must have a spare rank.
⚫
Memory mirroring mode
−
Comply with the general installation guidelines.
−
Each processor supports four integrated memory controllers (IMCs), and each IMC
has two channels for installing memory modules. The installed memory modules
must be identical in size and organization.
−
For a multi-processor configuration, each processor must have a valid memory
mirroring configuration.
⚫
Memory scrubbing mode
−
Comply with the general installation guidelines.
5.3.1.5 Memory Installation Positions
A server supports a maximum of 16 DDR4 memory modules. To maximize performance,
balance the total memory capacity between the installed processors and to load the channels
similarly whenever possible.
Observe the memory module installation rules when configuring memory modules. For
