DIMM Module Population Confi guration
For memory to work properly, follow the tables below for memory installation:
RDIMM Support POR on the E5-2600 Series Processor Platform

RDIMM Type
(RDIMM: Reg.=
Registered)
POR Speeds (in MHz) Ranks per DIMM
(Any
Combination)
1 1 Reg. ECC DDR3 800/1066/1333/1600 SR, DR, or QR
2 1 Reg. ECC DDR3 800/1066/1333/1600 SR, DR, or QR
2 2 Reg. ECC DDR3 800/1066/1333/1600 Mixing SR, DR, QR
Population Rules:
1. Any combination of x4 and x8 RDIMMs with 1 Gb or 2 Gb DRAM Density are supported.
2. Populate DIMMs starting with DIMM A1.
3. When mixing QR with SR or DR on the same DDR channel, put the QR in DIMMA1 fi rst.
Note: For the memory modules to work properly, please install DIMM modules in
pairs (with an even number of DIMMs installed).
Note: All channels in a system will run at the fastest common frequency.
