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.
• Confirm that the server supports the DIMM that you are installing, see http://www.lenovo.com/
serverproven/.
• The server supports only industry-standard double-data-rate 3 (DDR3), 1066 MHz PC3-8500, 1333
MHz PC3-10600, or 1600 MHz PC3-12800, (single-rank, dual-rank, or quad-rank in specified models),
registered or unbuffered, 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.
gggggeRxff-PC3v-wwwwwm-aa-bb-ccd
where:
– ggggg 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 ff is the device organization or bit width (for example, x4, x8, or x16)
4 = x4 organization (4 DQ lines per SDRAM)
8 = x8 organization
16 = x16 organization
– wwwww is the DIMM bandwidth, in MBps
8500 = 8.53 GBps (DDR3-1066 SDRAMs, 8-byte primary data bus)
.
