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.
