Installing a memory module
Use this information to install 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
on page
25).
If you are replacing a drive, make sure that:
• The server supports industry-standard, 1066, 1333 and 1600 MHz, PC3-12800 (single-rank or dual-rank)
double-data-rate 3 (DDR3), registered or unbuffered, synchronous dynamic random-access memory
(SDRAM) dual inline memory modules (DIMMs) with error correcting code (ECC). For a list of supported
options for the server, see
the list of options for the server.
• The maximum amount of memory that the server supports is dependent on the type of memory that you
install in the server.
• 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
utility" on page
80.
• The maximum operating speed of the server is determined by the slowest DIMM in the server.
• If you install a pair of DIMMs in DIMM connectors 1 and 3, the size and speed of the DIMMs that you
install in DIMM connectors 1 and 3 must match each other. However, they do not have to be the same
size and speed as the DIMMs that are installed in DIMM connectors 2 and 4.
• You can use compatible DIMMs from various manufacturers in the same pair.
