Memory Support Type |
(LRDIMM) – Load-Reduced DIMM, and (RDIMM) – Registered DIMM, or (DPCMM/PMem) – Intel Optane DC Persistent Memory. Typically, RDIMM’s are used up to 32GB/per memory module and have a lower latency. LRDIMMS are used for higher total capacity at 64GB and 128GB/per memory module with Intel’s optional PPM (Persistent Memory Module). RDIMMs and LRDIMMs are used with Intel Optane persistent memory. Each channel is populated with up to one DIMM of DRAM and one DIMM of PMem. That means that each CPU has up to 6 DIMMs of DRAM and 6 DIMMs of PMem. For best performance, it is recommended to have all 12 DIMMs slots per CPU populated. 2400W PSU is required. |
