HPE ProLiant ML350 Gen10 Server - Memory Configuration

Memory population guidelines

General memory population rules and guidelines

  • Install DIMMs only if the corresponding processor is installed.

  • If only one processor is installed in a two-processor system, only half of the DIMM slots are available.

  • To maximize performance, it is recommended to balance the total memory capacity between all installed processors.

  • When two processors are installed, balance the DIMMs across the two processors.

  • White DIMM slots denote the first slot to be populated in a channel. Mixing of DIMM types (UDIMM, RDIMM, and LRDIMM) is not supported.

  • The maximum memory speed is a function of the memory type, memory configuration, and processor model.

  • The maximum memory capacity is a function of the number of DIMM slots on the platform, the largest DIMM capacity qualified on the platform, the number and model of installed processors qualified on the platform.

  • To realize the performance memory capabilities listed in this document, HPE DDR4 SmartMemory is required. For more information, click here to view the HPE DDR4 SmartMemory QuickSpecs .
