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 NVDIMM-N User Guide at www.dell.com/ poweredgemanuals. Table 9.
