Installing A Memory Module - IBM System x3400 M3 Types 7378 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- or dual-rank DIMMs.
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 The server supports 1 GB, 2 GB, 4 GB, and 8 GB DIMMs, with a minimum of 1
Do not mix UDIMMs and RDIMMs in the same server.
