5.4.1.5 Memory Installation Positions

A 2488H V6 supports a maximum of 48 DDR4 DIMMs. 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 details, see
At least one DDR4 DIMM must be installed in the primary memory channels
corresponding to CPU 1.
Issue 03 (2021-02-01)
Install DIMMs only when corresponding processors are installed.
Do not install LRDIMMs and RDIMMs in the same server.
Install filler DIMMs in vacant slots.
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), and
each IMC has at least two channels (channels 1 and 2 or channels 1, 2,
and 3) for installing DIMMs. The installed DIMMs 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.
