1. The motherboard provides eight slots for DIMMs. You can add a pair of memory risers, each with four DIMM slots, making a total of 16 DIMMs in the server.
2. The memory configuration rules for the server are as follows:
    a. In all configurations, DIMMs must be identical (same size, same rank classification).
    b. In base configurations, all DIMM slots on the motherboard must be fully occupied (eight DIMMs).
    c. In upgrade configurations (16 DIMMs):
       1. DIMM slots on the motherboard must be fully occupied.
       2. Both memory risers must be installed, and both fully occupied.

Note - The DIMM sparing feature is available only when the optional memory risers are installed and fully occupied.

3. The memory configuration rules for the server are as follows:
    a. All eight memory risers must be installed in all configurations.
    b. In half-populated configurations (16 DIMMs), DIMMs must be installed in all CH0 slots. These slots have black ejector levers.
    c. 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.

3. Consider these population rules when installing, upgrading, or replacing DIMMs in a processor module:
    a. In half-populated configurations, 16 DIMMs must be installed in all CH0 slots (These slots have black ejector levers).
    b. In fully-populated configurations (32 DIMMs), DIMMs must be installed in all slots (CH0 and CH1).
