Intel® Server Board S5500HV/Intel® Server System SR1670HV TPS
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
Note: Although non-ECC memory can be used on this server board, Intel does not validate and
strongly discourages their use in a working server environment.
The following table shows the maximum memory amounts possible using RDIMM type memory:
NOTE: (1) Due to thermal requirements needed to support Quad Rank x4 DDR3 DIMMs, this
memory type is not supported in the Intel
type should be verified with other server chassis/system manufacturers planning to support this
server board.
