Memory module installation order

Memory modules must be installed in a specific order based on the memory configuration that you implement and the number of processors and memory modules installed in the compute node.

Memory installation requirements:

Attention:
  • Mixing x4 and x8 DIMMs in the same channel is allowed.

  • Install DIMMs of the same speed for optimal performance. Otherwise, the BIOS will find and run the lowest speed among all channels.

  • Always populate DIMMs with the maximum number of ranks in the farthest DIMM slot, followed by the nearest DIMM slot.
