Overview
The motherboard comes with eighteen (18) 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 figure illustrates the location of the DDR3 DIMM sockets:
