1.7 System memory
1.7.1 Overview
The motherboard comes with two 240-pin Double Data Rate 3 (DDR3) Dual Inline Memory
Modules (DIMM) sockets.
A DDR3 module has the same physical dimensions as a DDR2 DIMM. DDR3 DIMMs are
notched differently to prevent installation on a DDR2 DIMM socket. The following figure
illustrates the location of the sockets:
