Installing DIMMs

Memory configurations

The server has 24 system memory DIMM slots located on 4 memory expansion boards (6 DIMMs
per expansion board). You can access the memory expansion boards 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:
ESD safety precautions might result in damage to the server.

Memory expansion board 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
