System memory

2.4.1

Overview

The motherboard comes with eight (for CPU1) and four (for CPU2) 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.
