Memory Support
The X9SCM(-F)/X9SCL(-F) series supports up to 32GB of Unbuffered (UDIMM)
DDR3 ECC 1333/1066 MHz in 4 memory slots. Populating these DIMM modules
with a pair of memory modules of the same type and same size will result in
Slot 1, Channel 1
Slot 1, Channel 2
(Blue Slot)
Slot 2, Channel 2

interleaved memory, which will improve memory performance. Please refer to
the table below:

Note: Due to memory allocation to system devices, the amount of memory that
remains available for operational use will be reduced when 4 GB of RAM is used.
The reduction in memory availability is disproportional.
