4.4 Internal Connectors
4.4.1 Memory
Conventional SO-DIMM204 memory modules, as familiar from notebook computers, are used to equip
the board with memory. For technical and mechanical reasons it is possible that particular memory
modules cannot be employed. Please ask your distributor for recommended memory modules.
With currently available SO-DIMM204 modules a memory extension up to 16 GByte is possible
(DDR3L-1333) - depending on the variants components. Product variants with Intel® Atom processors
E3815 or E3825 provide only one memory socket. Therefore with those variants a memory extension is
possible only up to 8 GByte.
If both memory sockets are in use, notice that you must use identical memory modules.
All timing parameters for different memory modules are automatically set by BIOS.
