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 optional device connectors" on page 41 for the
location of the DIMM connectors):
v Confirm that the server supports the DIMM that you are installing, see
http://www.ibm.com/systems/info/x86servers/serverproven/compat/us/.
v The server supports only industry-standard double-data-rate 3 (DDR3), 1333
MHz PC3-10600R-999, 1066 MHz PC3-8500, or 1600 MHz PC3-12800,
(single-rank, dual-rank, or quad-rank), registered, synchronous dynamic
random-access memory (SDRAM) dual inline memory modules (DIMMs) with
error correcting code (ECC).
– The specifications of a DDR3 DIMM are on a label on the DIMM, in the
following format.
gGB eRxf-PC3-wwwwwm-a-b-c-d
where:
- gGB is the total capacity of the DIMM (for example, 1GB, 2GB, or 4GB)
- eR is the number of ranks
1R = single-rank
2R = dual-rank
4R = quad-rank
- x f is the device organization or bit width (for example, x4, x8, or x16)
4 = x4 organization (4 DQ lines per SDRAM)
8 = x8 organization
