Installing a memory module
The following notes describe the types of DIMMs that the server supports and other
information that you must consider when you install DIMMs.
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 server supports industry-standard double-data-rate 3 (DDR3), 1066, 1333, or
1600 MHz, PC3-6400, PC3-8500, PC3-10600, or PC3-12800 registered or
unbuffered, synchronous dynamic random-access memory (SDRAM) dual inline
memory modules (DIMMs) with error correcting code (ECC). See
http://www.ibm.com/systems/info/x86servers/serverproven/compat/us/ for a list of
supported memory modules for the server.
– The specifications of a DDR3 DIMM are on a label on the DIMM, in the
following format.
