Memory Support

The X10SAT supports up to 32GB of Unbuffered (UDIMM) DDR3 Non-ECC
1600/1333/1066 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:
Note: ECC memory is supported when an Intel ® Xeon™ processor is
installed.
P1-DIMMA1
P1-DIMMA2 (Blue Slot)
P1-DIMMB1
P1-DIMMB2 (Blue Slot)

Memory Population Guidelines

Please follow the table below when populating the X10SAT.

Notes
•
Be sure to use memory modules of the same type, same speed, same
frequency on the same motherboard. Mixing of memory modules of dif-
ferent types and speeds is not allowed.
•
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
article at Microsoft's Knowledge Base website at: http://support.microsoft.
