Installing A Memory Module - IBM 7380E1U Installation And User Manual

Installing a memory module

Attention:
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.
v The server supports industry-standard double-data-rate 3 (DDR3), 800, 1066, or
v At least one DIMM must be installed for the server to operate, but three DIMMs
v When two microprocessors are installed in the server, distribute the DIMMs
v The server supports a maximum of 16 single-, dual-, or quad-rank DIMMs. The
v The maximum number of single-, dual-rank, ECC supported UDIMM the server
v The memory controller has three registered DIMM channels per microprocessor
v Install DIMMs starting with the connector farthest from the microprocessor within
v When you install a quad-ranked DIMM in a channel with single- or dual-ranked
