Installing a memory module

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.

1 Microprocessor 1

2 Microprocessor 2

v The server supports industry-standard double-data-rate 3 (DDR3), 800, 1066, or

1333 MHz, PC3-10600R-999 (single-, dual-, or quad-rank), registered,

synchronous dynamic random-access memory (SDRAM) dual inline memory

modules (DIMMs) with error correcting code (ECC). See

http://www.lenovo.com/thinkserver and click the Options tab for a list of

supported memory modules for the server.

v At least one DIMM must be installed for each installed microprocessor for the

server to operate, but three DIMMs per microprocessor improves server

performance.

v When two microprocessors are installed in the server, distribute the DIMMs

between the two microprocessors to improve server performance.

v The server supports a maximum of 16 single-, dual-, or quad-rank DIMMs.

v The memory controller has three registered DIMM channels per microprocessor

(Channels 0, 1, and 2). Channels 0 and 1 support three DIMMs and Channel 2

supports two DIMMs.

v When installing DIMMs, install them starting with the connector farthest from the

microprocessor within each channel.

v When installing a quad-ranked DIMM in a channel with single- or dual-ranked

DIMMs, install the quad-ranked DIMM in the connector farthest from the

microprocessor.
