Beckhoff New Automation Technology CB4055
3.4 Memory
There is one conventional SO-DIMM204 socket available to equip the board with memory
(DDR3-1066/1333/1600). 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 4 GByte is possible. The timing
parameters for different memory modules are automatically set by BIOS.
