DRAM Installation order

Memory modules must be installed in a specific order based on the memory configuration that you implement on your node.

DRAM DIMM installation order

Note:
  • When adding one or more DIMMs during a memory upgrade, you might need to remove some DIMMs that are already installed to new locations.
