– 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:
ggg is 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
ff is the device organization (bit width)
4 = x4 organization (4 DQ lines per SDRAM)
8 = x8 organization
16 = x16 organization
wwwww is 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)
aa is the CAS latency, in clocks at maximum operating frequency
bb is the JEDEC SPD Revision Encoding and Additions level
cc is the reference design file for the design of the DIMM
d is the revision number of the reference design of the DIMM
v The 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).
v The 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
v The 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.
