Installing memory

The following notes describe the types of dual inline memory modules (DIMMs) that
your server supports and other information that you must consider when you install
DIMMs.
Attention:
v The server supports industry-standard double-data-rate 3 (DDR3), 800, 1066, or
v At least one DIMM must be installed for each installed microprocessor for the
v When two microprocessors are installed in the server, distribute the DIMMs
v The server supports a maximum of 16 single- or dual-rank DIMMs.
