Functional Architecture

Intel Confidential
Revision 1.2
Intel order number E69391-006
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:
Single Rank RDIMMs
800 MHz and 1066 MHz
48 GB
(12x 4GB DIMMs)
Dual Rank RDIMMs
800 MHz and 1066 MHz
96 GB
(12x 8GB DIMMs)
Quad Rank RDIMMs (1)
800 MHz only
96 GB
(12x 8GB DIMMs)
NOTE:
(1) Due to thermal requirements needed to support Quad Rank x4 DDR3 DIMMs, this
memory type is not supported in the Intel
®
Server System SR1670HV. Support for this memory
type should be verified with other server chassis/system manufacturers planning to support this
server board.
