2.5 System Memory
2.5.1 Overview
The motherboard comes with four 204-pin Double Data Rate 3 (DDR3) Small Outline Dual
Inline Memory Modules (SO-DIMM) sockets.
A DDR3 module has the same physical dimensions as a DDR SO-DIMM but has a 204-pin
footprint compared to the 204-pin DDR2 DIMM. DDR3 DIMMs are notched differently to
prevent installation on a DDR2 DIMM socket. The following figure illustrates the location of
the sockets:
