Parameter
Specifications
● a: The maximum number of DDR4 DIMMs is based on dual-processor
configuration. The value is halved for a server with only one processor.
● b: The maximum DDR4 memory capacity varies depending on the processor
type. The value listed in this table is based on the assumption that DIMMs
are fully configured.
● c: DPC (DIMM per channel) indicates the number of DIMMs per channel.
● d: If the Cascade Lake processor is used, the maximum operating speed of a
DIMM can reach 2933 MT/s. If the Skylake processor is used, the maximum
operating speed of a DIMM can reach 2666 MT/s only.
5.4.4 Memory Installation Guidelines
●
Observe the following when configuring DDR4 DIMMs:
–
Install DIMMs only when corresponding processors are installed.
–
Do not install LRDIMMs and RDIMMs in the same server.
–
Install filler DIMMs in vacant slots.
●
Observe the following when configuring DDR4 DIMMs 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 DIMMs
(channels 1 and 2, or channels 1, 2, and 3). The DIMMs 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
▪
Comply with the general installation guidelines.
5.4.5 Memory Installation Positions
A 2298 V5 supports a maximum of 12 DDR4 DIMMs. To maximize the
performance, balance the total memory capacity between the installed processors
and load the channels similarly whenever possible.
