1.5.1 SO-DIMM Sockets Location

A DDR3 module has the same physical dimensions as a DDR2 SO-DIMM but has a
204-pin footprint compared to the 200-pin DDR2 DIMM. DDR3 SO-DIMMs are notched
differently to prevent installation on a DDR2 SO-DIMM socket. The following figure
illustrates the location of the sockets:
