1. Ensure that you read the Safety instructions.
2. Follow the procedure listed in Before working inside your system.
3. Ensure that the memory module socket ejectors are in the unlocked position.
Steps
1. Align the processor blank with the memory module socket on the system board.
2. Lower the processor blank into the memory module socket, and press the blank firmly until the
memory module socket ejectors click into place.
Next steps
Follow the procedure listed in After working inside your system.
System memory
Your system supports DDR4 registered DIMMs (RDIMMs).
NOTE: MT/s indicates DIMM speed in MegaTransfers per second.
Memory bus operating frequency can be 1333 MT/s, 1600 MT/s, 1866 MT/s, or 2133 MT/s depending on
the following factors:
• DIMM type (RDIMM)
• Number of DIMMs populated per channel
• System profile selected (for example, Performance Optimized, Custom, or Dense Configuration
Optimized)
• Maximum supported DIMM frequency of the processors
The system contains 16 memory sockets split into two sets of 8 sockets, one set per processor. Each 8-
socket set is organized into four channels. In each channel, the release levers of the first socket are
marked white and the second socket black.
NOTE: DIMMs in sockets A1 to A8 are assigned to processor 1 and DIMMs in sockets B1 to B8 are
assigned to processor 2.
