Memory Support
The C7Q67 supports up to 32GB of Unbuffered (UDIMM) DDR3 Non-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:

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
