5.4.1.5 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.
