Memory mirrored channel

Memory mirrored channel mode replicates and stores data on two pairs of DIMMs within two channels simultaneously.

If a failure occurs, the memory controller switches from the primary pair of memory DIMMs to the backup pair of DIMMs. To enable memory mirrored channel through the Setup utility, select System Settings > Memory. For more information, see Using the Setup utility. When you use the memory mirrored channel feature, consider the following information:

The following table shows the installation sequence for memory mirrored channel mode:
