Installing a memory module
The following notes describe the types of dual inline memory modules (DIMMs) that
the server supports and other information that you must consider when you install
DIMMs (see “System-board internal connectors” on page 19 for the location of the
DIMM connectors):
v The server supports industry-standard, 1066 or 1333 MHz, PC3-10600R-999
(single-rank or dual-rank) double-data-rate 3 (DDR3), 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 The maximum amount of memory that the server supports is dependent on the
type of memory that you install in the server. See “Unbuffered DIMMs (UDIMMs)”
on page 39 and “Registered DIMMs (RDIMMs)” on page 40 for more information.
v The amount of usable memory is reduced, depending on the system
configuration. A certain amount of memory must be reserved for system
resources. To view the total amount of installed memory and the amount of
configured memory, run the Setup utility. For additional information, see “Using
the Setup Utility” on page 110.
v The maximum operating speed of the server is determined by the slowest DIMM
in the server.
v If you install a pair of DIMMs in DIMM connectors 2 and 5, the size and speed of
the DIMMs that you install in DIMM connectors 2 and 5 must match each other.
How ever, they do not have to be the same size and speed as the DIMMs that
are installed in DIMM connectors 1 and 4.
v You can use compatible DIMMs from various manufacturers in the same pair.
v When you install or remove DIMMs, the server configuration information
changes. When you restart the server, the system displays a message that
indicates that the memory configuration has changed.
v The specifications of a DDR3 DIMM are on a label on the DIMM, in the following
format.
