Memory Riser and DIMM Configuration

The server includes eight memory risers, each containing four DIMM slots. Four memory risers are associated with each CPU.

Either 16 or 32 DIMMs may be installed in the server.

The memory configuration rules for the server are as follows:

  • All eight memory risers must be installed in all configurations.

  • In half-populated configurations (16 DIMMs) DIMMs must be installed in all CH0 slots.

    These slots have black ejector levers.

  • In fully-populated configurations (32 DIMMs), DIMMs must be installed in all slots (CH0 and CH1)


    Note -  The DIMM sparing feature is available only in fully-populated servers.
  • All DIMMs associated with each processor must be identical (same size, same rank classification).

Mixed configurations are supported (DIMMs associated with CM0 with one size, and DIMMs associated with CM1 with a different size) as long as all DIMMs in the server have the same rank classification, and the number of DIMM in CM0 and CM1 are the same. For example, sixteen 32 Gbyte DIMMs associated with CM0, and sixteen 64 Gbyte DIMMs associated with CM1.
