Observe the following when configuring DDR4 memory modules 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 memory modules (channels 1
and 2, or channels 1, 2, and 3). 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.
−
Memory scrubbing mode
◼
Comply with the general installation guidelines.
5.4.1.5 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.
At least one DDR4 DIMM must be installed in the memory slots corresponding to CPU 1.
