The server supports only industry-standard double-data-rate 3 (DDR3), 800,
1066, 1333, or 1600 MHz, PC3-6400, PC3-8500, PC3-10600, or PC3-12800
registered or unbuffered, synchronous dynamic random-access memory
(SDRAM) dual inline memory modules (DIMMs) with error correcting code
(ECC). See http://www.ibm.com/systems/info/x86servers/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.
– ggggg eRxff PC3 v - wwwwwm - aa - bb - ccd
where:
-
ggggg is the total capacity of the DIMM (for example, 1GB, 2GB, or 4GB)
- eR is the number of ranks
v
1R = single-rank
v 2R = dual-rank
v
4R = quad-rank
- xff is the device organization (bit width)
v
x4 = x4 organization (4 DQ lines per SDRAM)
v
x8 = x8 organization
v
x16 = x16 organization
