Installing DIMMs
Memory configurations
The server has 24 system memory DIMM slots located on 4 memory risers (6 DIMMs per riser).
You can access the memory risers without removing the airflow guide or the I/O card cage.
The DIMMs are partitioned by the number of processors installed in the server. If you have only
one processor installed in the system, you can only use 12 of the 24 memory slots.
CAUTION: Observe all ESD safety precautions before attempting this procedure. Failure to follow
ESD safety precautions might result in damage to the server.
Memory riser locations and slot IDs
Install DIMMs into the risers attached to the system board. Each slot has a unique ID. For memory
riser locations, see Figure 2 (page 10).
