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, 1GB, 2GB, or 4GB)
– 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)
• Blank = 1.5 V specified
• L = 1.35 V specified, 1.5 V operable
Note: Values for these voltages are ‘specified’ which means the device characteristics such as
timing are supported at this voltage. Values are ‘operable’ which means that the devices can
be operated safely at this voltage. However, device characteristics such as timing may not
be guaranteed. All devices must be ‘tolerant’ of the highest DDR3 nominal voltage of 1.5 V,
meaning that they may not operate at 1.5 V but may be powered at that voltage without damage
to the devices.
– wwwww is the DIMM bandwidth, in MBps
6400 = 6.40 GBps (DDR3-800 SDRAMs, 8-byte primary data bus)
8500 = 8.53 GBps (DDR3-1066 SDRAMs, 8-byte primary data bus)
10600 = 10.66 GBps (DDR3-1333 SDRAMs, 8-byte primary data bus)
12800 = 12.80 GBps (DDR3-1600 SDRAMs, 8-byte primary data bus)
14900 = 14.93 GBps (DDR3-1866 SDRAMs, 8-byte primary data bus)
– m is the DIMM type
E = Unbuffered DIMM (UDIMM) with ECC (x72-bit module data bus)
L = Load Reduction DIMM (LRDIMM)
R = Registered DIMM (RDIMM)
U = Unbuffered DIMM with no ECC (x64-bit primary data bus)
– aa is the CAS latency, in clocks at maximum operating frequency
