supported options for the server, see http://www.lenovo.com/thinkserver; then, select your country and navigate to the list of options 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 a maximum of 12 single-rank or dual-rank DIMMs.

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 three single-rank or dual-rank DIMMs per channel. The following table shows an example of the maximum amount of memory that you can install, using ranked DIMMs.

Table 6. Maximum memory installation using ranked DIMMs

Number of DIMMs	DIMM type	DIMM size		Total memory
12	Single-rank DIMMs	4	GB	48 GB
12	Dual-rank DIMMs	4	GB	48 GB
12	Dual-rank DIMMs	8	GB (if available)	96 GB

vThe DIMM options that are available for the server are 1 GB, 2 GB, 4 GB, and 8 GB (when available). The server supports a minimum of 2 GB and a maximum of 96 GB of system memory.
