For memory frequency of 2933 MT/s, one DIMM per channel issupported.● Maximum supported DIMM speed of the processors. For memory frequency of 2933 MT/s, two DIMM per channel issupported on RDIMM.● Maximum supported speed of the DIMMsNOTE: MT/s indicates DIMM speed in MegaTransfers per second.The system supports Flexible Memory Configuration, enabling the system to be configured and run in any valid chipsetarchitectural configuration. The following are the recommended guidelines for installing memory modules:● All DIMMs must be DDR4.● RDIMMs and LRDIMMs must not be mixed.● NVDIMMs and LRDIMMs must not be mixed.● NVDIMMs and RDIMMs can be mixed.● 64 GB LRDIMMs that are DDP (Dual Die Package) LRDIMMs must not be mixed with 128 GB LRDIMMs that are TSV(Through Silicon Via/3DS) LRDIMMs.● x4 and x8 DRAM based memory modules can be mixed.● Up to two RDIMMs can be populated per channel regardless of rank count.● Up to two LRDIMMs can be populated per channel regardless of rank count.● A maximum of two different ranked DIMMs can be populated in a channel regardless of rank count.● If memory modules with different speeds are installed, they will operate at the speed of the slowest installed memorymodule(s).● Populate memory module sockets only if a processor is installed.○ For single-processor systems, sockets A1 to A12 are available.○ For dual-processor systems, sockets A1 to A12 and sockets B1 to B12 are available.● Populate all the sockets with white release tabs first, followed by the black release tabs.● When mixing memory modules with different capacities, populate the sockets with memory modules with the highestcapacity first.NOTE: For example, if you want to mix 8 GB and 16 GB memory modules, populate 16 GB memory modules in thesockets with white release tabs and 8 GB memory modules in the sockets with black release tabs.● Memory modules of different capacities can be mixed provided other memory population rules are followed.NOTE: For example, 8 GB and 16 GB memory modules can be mixed.● In a dual-processor configuration, the memory configuration for each processor must be identical.Installing and removing system components 73
