Mirroring mode
In mirroring mode, each DIMM in a pair must be identical in size and architecture. The channels are grouped
in pairs with each channel receiving the same data. One channel is used as a backup of the other, which
provides redundancy.
Note: All DIMMs to be installed must be the same type with the same capacity, frequency, voltage, and
ranks.
The following table shows the DIMM population sequence for mirroring mode when only one processor
(CPU1) is installed.
