ASUS Z9PE-D8 WS 2-13
2.4 System memory
2.4.1 Overview
The motherboard comes with eight (four DIMM per CPU) Double Data Rate 3
(DDR3) Dual Inline Memory Modules (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 gure illustrates the location of the DDR3 DIMM sockets:
