DIMM Configuration Changes
Dell EMC recommends that NVDIMM-N data contents be backed up to external storage before making any changes to the
server memory configuration. This applies to both NVDIMM-Ns and RDIMMs. Due to memory Error Correction (ECC) algorithms
that are unique to each memory slot and memory configuration, NVDIMM-Ns may generate errors after a memory configuration
change. If the server DIMM configuration changes, it is recommended that the NVDIMM-N be erased and reset to factory
defaults in BIOS Setup prior to utilization.
In the scenario where the DIMMs (both RDIMMs and NVDIMM-Ns) must be moved or the system board must be replaced, all
DIMMs must be repopulated in the exact same slot as in the original server. The only migration scenario that is supported is a
slot for slot replacement between system boards. Dell EMC also recommends that BIOS NVDIMM settings are identical.
