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.
• 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.
• The server supports only industry-standard double-data-rate 3 (DDR3), 800, 1066, 1333, 1600, or
1866 MHz, PC3-6400, PC3-8500, PC3-10600, PC3-12800, or PC3-14900 registered or unbuffered,
synchronous dynamic random-access memory (SDRAM) dual inline memory modules (DIMMs) with
error correcting code (ECC). See http://www.lenovo.com/ serverproven/ 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.
gggggeRxff PC3 v - wwwwwm - aa - bb - ccd
where:
– ggggg is the total capacity of the DIMM (for example, 1 GB, 2 GB, or 4 GB)
– eR is the number of ranks
1R = single-rank
2R = dual-rank
4R = quad-rank
– xff is the device organization (bit width)
x4 = x4 organization (4 DQ lines per SDRAM)
x8 = x8 organization
x16 = x16 organization
– v is the SDRAM and support component supply voltage (VDD)
