Memory Support
The X9SCi-LN4/X9SCA 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
interleaved memory, which will improve memory performance. Please refer to
the table below:
Memory Population Guidelines

Notes
•
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. See the
following table for details.

For Microsoft Windows users: Microsoft implemented a design change in the
Windows XP with Service Pack 2 (SP2) and Windows Vista. This change is
specific to the behavior of Physical Address Extension (PAE) mode which
improves driver compatibility. For more information, please read the following
