Memory cards and memory modules (DIMM)
This topic provides information about memory cards and memory modules
(DIMM).
About this task
The following notes describe the types of dual inline memory modules (DIMMs)
that the server supports and other information that you must consider when you
install DIMMs:
v To confirm that the server supports the memory modules that you are installing,
see http://www.ibm.com/systems/info/x86servers/serverproven/compat/us/.
v All server machine types that are described in this document support 240-pin,
double-data-rate (DDR) III, registered synchronous dynamic random-access
memory (SDRAM) with error correcting code (ECC) DIMMs. These DIMMs
must be compatible with the latest PC3-10600 or PC3-8500 SDRAM registered
DIMM specifications.
– All machine types support 1.5 V DIMMs; machine types 7143 and 7191 also
support 1.35 V DIMMs.
– All machine types support 2 GB PC3-10600 DIMMs and 4 GB, 8 GB, 16 GB,
and 32 GB (when available) PC3-8500 DIMMs; machine types 7145 and 7146
also support 1 GB DIMMs.
v The server supports up to eight memory cards. Each memory card holds up to
eight DIMMs.
v The Intel 7500 Scalable Memory Buffer and the Intel 7510 Scalable Memory
Buffer are not interchangeable and cannot be used in the same server. To verify
