Figure 6: Memory mirroring in a 6 or 8 CPUMEMR configuration
On both CPUMEMRs of the mirroring pair, the size of the DIMMs must be the
same within the following groups of memory modules, see
DIMM# (1B, 1D, 1F, 1H)
●
DIMM# (1A, 1C, 1E, 1G)
●
DIMM# (2B, 2D, 2F, 2H)
●
DIMM# (2A, 2C, 2E, 2G)

Scenarios for memory mirroring interruption
If failed or disabled DIMM memory modules are detected, the impact on the
mirroring configuration is:
1. A group of DIMM memory modules is deactivated:
– 4 CPU configuration: 2 DIMM memory modules
– 6 or 8 CPU configuration: 4 DIMM memory modules
2. If the active DIMM memory modules do not form a valid mirroring
configuration due to lacking mirroring pairs, the BIOS boots without mirroring
configuration.
3. If the active DIMM memory modules form a valid mirroring configuration, the
BIOS keeps mirroring configuration with the remaining DIMM memory
modules.
