DIMMs Memory configurations The server has 24 system memory DIMM slots located on four memory riser boards (six DIMMs per riser). You can access the memory riser boards without removing the airflow guide or the I/O card cage. The DIMMs are partitioned by the number of processors installed into the server. If you have 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 can result in damage to the server. Memory riser board locations and slot IDs Install DIMMs into the appropriate risers attached to the system board; each slot has a unique ID. See Figure 1-2 "System board components " for memory riser locations.
