General memory module installation guidelines

To ensure optimal performance of your system, observe the following general guidelines when configuring your system memory. If your system's memory configuration fails to observe these guidelines, your system might not boot, stop responding during memory configuration, or operate with reduced memory.

The memory bus may operate at speeds of 5600 MT/s, 4800 MT/s, 4400 MT/s, or 4000 MT/s depending on the following factors:

  • System profile selected (for example, Performance, Performance Per Watt Optimized (OS), or Custom [can be run at high speed or lower])
  • Maximum supported DIMM speed of the processors
  • Maximum supported speed of the DIMMs
NOTE: MT/s indicates DIMM speed in MegaTransfers per second.
NOTE: Fault Resilient Memory supports only eight and sixteen DIMMs per processor.
  • All DIMMs must be DDR5.
  • Memory mixing is not supported for:
    • Different DIMM capacities
    • X4 and X8 DRAM memory modules
    • 3DS and non-3DS RDIMMs
      NOTE:3DS is a DRAM technology that is used to manufacture the highest capacity DIMMs. See your DIMM documentation for additional details.
  • Modes supported in Xeon Max processor:
    • Xeon Max only without DIMMs
    • Cache with DIMMs
    • Flat with DIMMs
  • Supported RDIMM configurations per Xeon Max processor:
    • 0 DIMM (Xeon Max only mode)
    • 1 DIMM (Flat mode)
    • 2 DIMM (Flat mode)
    • 4 DIMMs (Cache or Flat mode)
    • 8 DIMMs (Cache or Flat mode)
    • 16 DIMMs (Cache or Flat mode)
  • DDR5/Xeon Max memory ratio must be in the range of 2:1 ~ 64:1 for cache mode.
    NOTE:Each Xeon Max processor has 64 GB integrated memory.
  • The combination of Flat and Cache modes is not supported.
  • NOTE: Fault Resilient Memory is only available in Flat mode, with eight or sixteen DIMMs per processor.
  • If memory modules with different speeds are installed, they operate at the speed of the slowest installed memory module(s).
  • Populate memory module sockets only if a processor is installed.
    • For single-processor systems, sockets A1 to A16 are available.
    • For dual-processor systems, sockets A1 to A16 and sockets B1 to B16 are available.
    • A minimum of one DIMM must be populated for each installed processor.
  • In Optimizer Mode, the DRAM controllers operate independently in the 64-bit mode and provide optimized memory performance.
    Table 1. Memory population rulesThe below table describes the memory population information.
    Processor Memory population Memory population information
    Single processor A{1}, A{2}, A{3}, A{4}, A{5}, A{6}, A{7}, A{8}, A{9}, A{10}, A{11}, A{12}, A{13}, A{14}, A{15}, A{16} 1, 2, 4, 6, 8, 12 or 16 DIMMs are allowed.
    Dual processor (Start with processor1. Processor 1 and processor 2 population should match) A{1}, B{1}, A{2}, B{2}, A{3}, B{3}, A{4}, B{4}, A{5}, B{5}, A{6}, B{6}, A{7}, B{7} A{8}, B{8}, A{9}, B{9}, A{10}, B{10}, A{11}, B{11}, A{12}, B{12}, A{13}, B{13}, A{14}, B{14}, A{15}, B{15}, A{16}, B{16} 2, 4, 8, 12, 16, 24 or 32 DIMMs are supported per system.
    Table 2. Memory population rules for Xeon Max processorThe below table describes the memory population information.
    Processor Memory population Memory population information
    Single processor A{1}, A{2}, A{3}, A{4}, A{5}, A{6}, A{7}, A{8}, A{9}, A{10}, A{11}, A{12}, A{13}, A{14}, A{15}, A{16} 0, 1, 2, 4, 8, or 16 DIMMs are allowed.
    Dual processor (Start with processor1. Processor 1 and processor 2 population should match) A{1}, B{1}, A{2}, B{2}, A{3}, B{3}, A{4}, B{4}, A{5}, B{5}, A{6}, B{6}, A{7}, B{7} A{8}, B{8}, A{9}, B{9}, A{10}, B{10}, A{11}, B{11}, A{12}, B{12}, A{13}, B{13}, A{14}, B{14}, A{15}, B{15}, A{16}, B{16} 0, 2, 4, 8, 16, or 32 DIMMs are supported per system.
  • Populate all the sockets with white release tabs first, followed by the sockets with black release tabs.
  • Unbalanced or odd memory configurations result in a performance loss, and the system may not identify the memory modules being installed. Always populate memory channels identically with equal DIMMs for the best performance.
  • Supported RDIMM configurations are 1, 2, 4, 6, 8, 12, or 16 DIMMs per processor.
