−
Install filler memory modules in vacant slots.
⚫
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.
5.3.1.5 Memory Installation Positions
A CH242 V5 supports a maximum of 48 DDR4 DIMMs. To maximize the performance,
balance the total memory capacity between the installed processors and load the channels
similarly whenever possible.
