Chapter 2: Motherboard information
2.5 System memory
This motherboard comes with four Double Data Rate 3 (DDR3) Dual Inline Memory Module
(DIMM) sockets. A DDR3 module has the same physical dimensions as a DDR2 DIMM but
is notched differently to prevent installation on a DDR2 DIMM socket. DDR3 modules are
developed for better performance with less power consumption.
The figure below illustrates the location of the DDR3 DIMM sockets:
