Replacing a memory module (DIMM)

To replace a dual inline memory module (DIMM), use the following information and procedures:

Supported memory types

Following is information that describes 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 internal connectors” on page 107 for the location of the DIMM connectors).

vThe server supports only industry-standard double-data-rate 3 (DDR3), 1066 or 1333 MHz, PC3-6400, PC3-8500, or PC3-10600 (single-rank, dual-rank, or quad-rank), registered or unbuffered, synchronous dynamic random-access memory (SDRAM) dual inline memory modules (DIMMs) with error correcting code (ECC). See http://www.lenovo.com/thinkserver 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. ggg eRxff-PC3-wwwwwm-aa-bb-cc

where:

gggis the total capacity of the DIMM (for example, 1GB, 2GB, or 4GB)

e is the number of ranks

1 = single-rank

2 = dual-rank

4 = quad-rank

ffis the device organization (bit width)

4 = x4 organization (4 DQ lines per SDRAM)

8 = x8 organization

16 = x16 organization

wwwwwis the DIMM bandwidth, in MBps

6400 = 6.40 GBps (PC3-800 SDRAMs, 8-byte primary data bus)

8500 = 8.53 GBps (PC3-1066 SDRAMs, 8-byte primary data bus)

10600 = 10.66 GBps (PC3-1333 SDRAMs, 8-byte primary data bus)

12800 = 12.80 GBps PC3-1600 SDRAMs, 8-byte primary data bus)

m is the DIMM type

E = Unbuffered DIMM (UDIMM) with ECC (x72-bit module data bus)

R = Registered DIMM (RDIMM)

U = Unbuffered DIMM with no ECC (x64-bit primary data bus)

aais the CAS latency, in clocks at maximum operating frequency

bbis the JEDEC SPD Revision Encoding and Additions level

ccis the reference design file for the design of the DIMM

d is the revision number of the reference design of the DIMM

vThe server supports unbuffered DIMMs (UDIMM) or registered DIMMs (RDIMM).

vThe server supports a maximum of six single-rank or dual-rank DIMMs, depending on the type of DIMM you install in the server.

Note: To determine the type of a DIMM, see the label on the DIMM. The information on the label is in the format xxxxx nRxxx PC3-xxxxx-xx-xx-xxx. The numeral in the sixth numerical position indicates whether the DIMM is single-rank (n=1) or dual-rank (n=2).

vThe server supports up to two UDIMMs or three RDIMMs per channel. The following table shows an example of the maximum amount of memory that you can install, using ranked DIMMs.
