Memory Support

The X8STi/X8STi-F/X8STi-3F/X8STi-LN4 supports up to 24 GB unbuffered ECC or
Non ECC DDR3 1333/1066/800 in 6 DIMM slots.
Populating these DIMM slots with sets of three memory modules of the same type
and same size (at least one module per channel) will result in interleaved memory,
which improves memory performance. (i.e., install one module each on DIMM slots
DIMM1A, DIMM2A and DIMM3A).
