A support engineer is installing DIMMs of different speeds and voltages in a ProLiant DL380p
Gen8 Server. Which rules for DIMM installation must the engineer follow during this installation?

A.
UDIMMs, RDIMMs, and LRDIMMs may be mixed in the same bank in the server if only one
processor is installed.

B.
DIMMs of different speeds may be mixed in any order. The server will select the lowest
common speed.

C.
RDIMMs operating at either 1.35V or 1.5V may be mixed in any order. The system will operate
at the lower voltage.

D.
Four quad-ranked LRDIMMs are supported across all memory channels. The server balances
capacity automatically.
