2.4.1Overview

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 figure illustrates the location of the DDR3 DIMM sockets:

Channel	Sockets
Channel A	DIMM_A1 and DIMM_A2
Channel B	DIMM_B1 and DIMM_B2

This chipset officially supports DDR3 1066/800. With the ASUS Super Memspeed Technology, the motherboard supports up to 1333MHz and provides more ratio setting items than the chipset officially supports. Refer to the table below for details.

FSB			1600				1333			1066
DDR3	1600	1333	1200	1000	800	1333	1111	1000	833	889

2.4.2Memory configurations

You may install 512 MB, 1 GB, and 2 GB unbuffered non‑ECC DDR3 DIMMs into the DIMM sockets.
