Chapter 2: Hardware information

2.4 System memory

2.4.1 Overview

The motherboard comes with four 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:

2.4.2 Memory Congurations

You may install 2 GB, 4 GB, and 8 GB Unbuffered with ECC DDR3 DIMMs into the

DIMM sockets using the memory congurations in this section.

• Always install DIMMs with the same CAS latency. For optimum compatibility, it is

recommended that you obtain memory modules from the same vendor.

• Start installing the DIMMs in slots A2 and B2 (Blue).
