3.6 Memory

Conventional SO-DIMM200 memory modules, as familiar from notebook computers, are used to equip

the board with memory. For mechanical reasons it is possible that particular memory modules cannot be

employed. Please ask your distributor for recommended memory modules.

With currently available SO-DIMM200 modules a memory extension up to 2 GByte is possible (DDR2-

667).

All timing parameters for different memory modules are automatically set by BIOS.
