type. The value listed in this table is based on the assumption that memory
modules are fully configured.
memory module can reach 2933 MT/s. If the Skylake processor is used, the
maximum operating speed of a memory module can reach 2666 MT/s only.
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 two integrated memory controllers (IMCs).
At least two channels of each IMC are used for installing memory
modules (channels 1 and 2, or channels 1, 2, and 3). The memory
modules installed must be identical in size and organization.
▪
For a multi-processor configuration, each processor must have a
valid memory mirroring configuration.
– Memory scrubbing mode
