Memory module installation rules and order
Memory modules must be installed in a specific order based on the memory configuration that is implemented in the server.
Note
Make sure to follow the population combinations in this topic. Otherwise, some of the memory modules might not be recognized by the system.
The following memory configurations are available:
- DRAM DIMMs
- PMEM + DRAM DIMMs (see PMEM rules for the rules and configuration options)
See the following for memory module location and mapping to channel and iMC.
