Memory Support

Supported memory follows the DDR3 specification and meets the following characteristics:
800 MHz, 1066 MHz or 1333 MHz operating frequencies
Single-rank (SR), dual-rank (DR), and quad-rank (QR)
Registered DIMM (RDIMM) or Unbuffered DIMM (UDIMM)
RDIMMs must be ECC only
UDIMMs can be ECC or non-ECC and can be mixed within a common
configuration
The Channel Independent mode is the only memory RAS mode that supports
non-ECC DIMMs.
The presence of a single non-ECC UDIMM results in the disabling of ECC
functionality.
RDIMMs and UDIMMs cannot be mixed within a common system memory
configuration
The following table shows the maximum memory amounts using RDIMM type memory:
NOTE: Due to thermal requirements needed to support Quad Rank x4 DDR3 DIMMs, the Intel
Server System SR1670HV does not support this memory type.
