− 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.

− Comply with the general installation guidelines.
5.1.4.1.5 Memory Installation Positions
A server supports a maximum of 32 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
details, see Memory Configuration Assistant.
At least one DDR4 memory module must be installed in the primary memory channels
corresponding to CPU 1.
