memory that is reserved for system resources depends on the operating system,
the configuration of the server, and the configured PCI devices.
Note: If you install a ServeRAID-M1015 SAS/SATA adapter, make sure at least 2
GB of memory is installed in the server before you run DSA from a bootable CD.
v
The maximum operating speed of the server is determined by the slowest DIMM
in the server.
v The server can operate in three modes: sparing, mirroring and independent
channel modes.
Note: Memory sparing is only available for Intel Xeon 5600 series
microprocessor.
In two-DIMM-per-channel configuration, a server with an Intel Xeon X5600 series
microprocessor automatically operates with a maximum memory speed of up to
1333 MHz when one of the following conditions is met:
v
Two 1.5 V single-rank or dual-rank RDIMMs are installed in the same channel. In
the Setup utility,
Memory speed is set to Max performance mode
v
Two 1.35 V single-rank or dual-ranl RDIMMs are installed in the same channel.
In the Setup utility,
Memory speed is set to Max performance and LV-DIMM
power is set to Enhance performance mode. The 1.35 V RDIMMs will function
at 1.5 V
The following notes describe the types of DIMMs that the server supports and other
information that you must consider when you install DIMMs.
v 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.
v
The server supports only industry-standard double-data-rate 3 (DDR3), 800,
1066, or 1333 MHz, PC3-10600R-999, registered or unbuffered, synchronous
dynamic random-access memory (SDRAM) dual inline memory modules (DIMMs)
with error correcting code (ECC). See http://www.ibm.com/servers/eserver/
serverproven/compat/us/ 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 e Rx ff -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)
