Description

How to properly populate memory modules on dual-socket Intel® Server Boards?

Resolution

As a general rule of thumb, for each installed CPU, correspondingly populate the blue  slots first, starting from the slot farthest from the processor.

Refer to the Memory Subsystem section of the Technical Product Specifications (TPS) document for your particular dual processing Intel® Server Board for the complete memory population rules.

Additionally, it would also be important to check into the tested memory list. Therefore, you ensure that you use officially validated memory on your board.

Note
  • Mixing of DDR4 DIMM Types (RDIMM, LRDIMM, 3DS-RDIMM, 3DS-LRDIMM, NVDIMM) within a channel or socket or across sockets isn't supported. This is a Fatal Error Halt in Memory Initialization.
  • Mixing DIMMs of different frequencies and latency isn't supported within or across processor sockets. If a mixed configuration is encountered, the BIOS attempts to operate at the highest common frequency and the lowest latency possible.
