4.3 Memory
There is one conventional SoDIMM200 socket available to equip the board with memory (DDR2-667). It is
located on the bottom side of the board. For mechanical reasons it is possible that particular memory
modules cannot be employed. Please ask your distributor for recommended memory modules.
With currently available SoDIMM modules a memory extension up to 2 GByte is possible. The timing
parameters for different memory modules are automatically set by BIOS.
