4.4 Memory

There is one conventional SO-DIMM200 socket available to equip the board with memory (DDR2-667). 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.
