NOTE:
For example, if you populate socket A1 for processor 1, then populate socket B1 for processor 2, and so on.
● Mixing of more than two memory module capacities in one system is not supported.
● Unbalanced memory configurations will result in a performance loss so always populate memory channels identically with
identical DIMMs for best performance.
● Populate six identical memory modules per processor (one DIMM per channel) at a time to maximize performance.
DIMM population update for Performance Optimized mode with quantity of 4 and 8 DIMMs per processor.
● When the DIMM quantity is 4 per processor, the population is slot 1, 2, 4, 5.
● When the DIMM quantity is 8 per processor, the population is slot 1, 2, 4, 5, 7, 8, 10, 11 (2-2-2 platforms).
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.
● 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
poweredgemanuals.
