5.4.4 Memory Installation Guidelines
● Observe the following when conguring DDR4 DIMMs:
– Install DIMMs only when corresponding processors are installed.
– Do not install LRDIMMs and RDIMMs in the same server.
– Install
ller DIMMs in vacant slots.
● Observe the following when conguring DDR4 DIMMs in specic operating
mode:
– Memory sparing mode
▪ Comply with the general installation guidelines.
▪ Each memory channel must have a valid online spare conguration.
▪ The channels can have dierent online spare congurations.
▪ 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
conguration, each processor must have a
valid memory mirroring conguration.
– Memory scrubbing mode
▪
Comply with the general installation guidelines.
5.4.5 Memory Installation Positions
A 2488 V5 supports a maximum of 32 DDR4 DIMMs. To maximize the
performance, balance the total memory capacity between the installed processors
and load the channels similarly whenever possible.
At least one DDR4 DIMM must be installed in the memory slots corresponding to
CPU 1.
