3.4 Memory
There is one conventional SO-DIMM204 socket available to equip the board with memory
(DDR3-800/1066). It is located on the bottom side of the board. For technical and mechanical reasons it
is possible that particular memory modules cannot be employed. Please ask your sales representative for
recommended memory modules.
With currently available SO-DIMM modules a memory extension up to 2 GByte is possible. The timing
parameters for different memory modules are automatically set by BIOS.

It is not necessary that the memory modules' rated speed and the motherboard's specified memory bus
speed match exactly. The system will automatically configure the fastest mutually supported memory bus
speed available. For best performance, however, the memory modules' rated speed should be equal to or
faster than the motherboard's specified memory bus speed.
