When the DIMM quantity is 8 per processor, the population is slot 1, 2, 4, 5, 7, 8, 10, 11.
NVDIMM-N memory module installation guidelines
The following are the recommended guidelines for installing NVDIMM-N memory modules:
●
Each system supports memory configurations with 1, 2, 4, 6, or 12 NVDIMM-Ns.
●
Supported configurations have dual processors and a minimum of 12x RDIMMs.
●
Maximum of 12 NVDIMM-Ns can be installed in a system.
●
NVDIMM-Ns or RDIMMs must not be mixed with LRDIMMs.
●
DDR4 NVDIMM-Ns must be populated only on the black release tabs on processor 1 and 2.
●
For systems with four processors, RDIMMs populated on processor 3 and 4 must be identical to the number of RDIMMs
populated on processor 1 and 2.
●
All slots on configurations 3, 6, 9, and 12 can be used, but a maximum of 12 NVDIMM-Ns can be installed in a system.
NOTE:
NVDIMM-N memory slots are not hot-pluggable.
For more information about the supported NVDIMM-N configurations, see the
