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

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

10600 = 10.66 GBps (PC3-1333 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

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).

The following sections provide additional information specific to unbuffered and registered DIMMs that you must consider.

Unbuffered DIMMs (UDIMMs)

The following notes provide information that you must configure when you install UDIMMs:

vThe memory channels run at the fastest common frequency of the installed DIMMs.

vDo not use both UDIMMs and RDIMMs in the same server.

vUsing ECC and non-ECC UDIMMs in the server will cause the server to run in non-ECC mode.

vThe UDIMM options that are available for the server are 1 GB, 2 GB, and 4 GB (when available) memory DIMMs.

vYou can install a maximum of 16 GB of memory in some server models when you use UDIMMs.

vThe server supports up to two single-rank or dual-rank UDIMMs per channel.

vDIMM slots 3 and 6 are not supported when you install UDIMMs in the server. Do not install DIMMs in these connectors.
