A. Install memory DIMMs of different speeds and sizes in pairs in adjoining sockets on the same memory data bus.

B. On a Single-CPU server, install the first memory DIMM in channel one, the second in Channel two, the third in channel three, and so on.

C. For best reliability, install DIMMs of different speeds and sizes in a single memory channel.

D. To maximize performance, balance the total memory capacity across all installed processors, and load the channels similarly.
