To attain top performance, ASUS engineers have successfully unleashed the
true potential of DDR2 memory. While in DDR2 1066 mode, ASUS’s exclusive
technology offers a choice of FSB 1333, providing great performance for 3D
graphics and other memory demanding applications. See page 2-19 for details.

1-2 Chapter 1: Product Introduction

DDR2 memory support

The motherboard supports DDR2 memory that features data transfer rates of

800/667 MHz to meet the higher bandwidth requirements of the latest 3D graphics,

multimedia, and Internet applications. The dual-channel DDR2 architecture
doubles the bandwidth of your system memory to boost system performance,
eliminating bottlenecks with peak bandwidths of up to 12.8 GB/s. Furthermore, this

motherboard does not restrict the memory size across two channels. Users may
install different memory size DIMMs into the two channels and enjoy dual-channel
and single-channel functions at the same time. This new feature optimizes the use
of available memory size. See page 2-19 for details.

ASUS Super Memspeed Technology

To attain top performance, ASUS has managed to break through current FSB

and DRAM ratio proportions by utilizing Super Memspeed Technology–the latest

technology that provides even more precise overclocking options to unleash the

true potential of DDR2 memory. The DDR2 Mode maximizes system performance
by eliminating the bottleneck when overclocking both the CPU and memory–

providing great performance for 3D graphics and other memory demanding
applications. See page 2-19 for details.

Serial ATA 3.0 Gb/s technology

This motherboard supports the next-generation hard drives based on the Serial

ATA (SATA) 3Gb/s storage specication, delivering enhanced scalability and

doubling the bus bandwidth for high-speed data retrieval and saves. See page
2-33 for details.

Dual Gigabit LAN

The integrated dual Gigabit LAN design allows a PC to serve as a network

gateway for managing trafc between two separate networks. This capability

ensures rapid transfer of data from WAN to LAN without any added arbitration or
latency. See page 2-30 for details.

IEEE 1394a support

The IEEE 1394a interface provides high speed digital interface for audio/video
appliances such as digital television, digital video camcorders, storage peripherals
& other PC portable devices. See pages 2-31 and 2-35 for details.

ROG Blitz Formula 1-3

Green ASUS

This motherboard and its packaging comply with the European Union’s Restriction

on the use of Hazardous Substances (RoHS). This is in line with the ASUS vision

of creating environment-friendly and recyclable products/packaging to safeguard

consumers’ health while minimizing the impact on the environment.

1.3.2 ROG Intelligent Performance & Overclocking features

Crosslinx

Crosslinx is a unique technology utilizing a dedicated special graphics controller
to optimize PCIe allocation with dual x8 lanes. Such architecture eliminates the x4

bottleneck found on competing x16, x4 solutions. Hence, the Crosslinx is able to
provide faster graphics performance.

Fusion Block System

Building on the ROG unique heatpipe, the Fusion Block System (FBS) provides
dual paths to cool down the motherboard. Users will be able to connect the FBS
with the watercooling circuit.

Component Overheat Protection -EX (COP EX)

When the temperature of Northbridge and Southbridge reaches the limit of

specications, the motherboard will automatically shut down to protect NB and SB

from burning.

2-Phase DDR2

• Some old-version DDR2-800 DIMMs may not match Intel®’s
On-Die-Termination (ODT) requirement and will automatically downgrade
to run at DDR2-667. If this happens, contact your memory vendor to check
the ODT value.

• Due to chipset limitation, DDR2-800 with CL=4 will be downgraded to run
at DDR2-667 by default setting. If you want to operate with lower latency,
adjust the memory timing manually.

2.4.3 Installing a DIMM

Unplug the power supply before adding or removing DIMMs or other
system components. Failure to do so can cause severe damage to both the
motherboard and the components.

To install a DIMM:

1. Unlock a DIMM socket by pressing
the retaining clips outward.

2. Align a DIMM on the socket
such that the notch on the DIMM
matches the break on the socket.

3. Firmly insert the DIMM into the

1

socket until the retaining clips
snap back in place and the DIMM
is properly seated.

• A DDR2 DIMM is keyed with a notch so that it ts in only one direction. Do

not force a DIMM into a socket to avoid damaging the DIMM.

• The DDR2 DIMM sockets do not support DDR DIMMs. Do not install DDR
DIMMs to the DDR2 DIMM sockets.

2.4.4 Removing a DIMM

To remove a DIMM:

1. Simultaneously press the retaining
clips outward to unlock the DIMM.

2.5 Expansion slots

In the future, you may need to install expansion cards. The following sub-sections
describe the slots and the expansion cards that they support.

Make sure to unplug the power cord before adding or removing expansion
cards. Failure to do so may cause you physical injury and damage motherboard
components.

2.5.1 Installing an expansion card

To install an expansion card:

1. Before installing the expansion card, read the documentation that came with
it and make the necessary hardware settings for the card.

2. Remove the system unit cover (if your motherboard is already installed in a
chassis).

3. Remove the bracket opposite the slot that you intend to use. Keep the screw
for later use.

4. Align the card connector with the slot and press rmly until the card is

completely seated on the slot.

5. Secure the card to the chassis with the screw you removed earlier.

6. Replace the system cover.

2.5.2 Conguring an expansion card

After installing the expansion card, congure it by adjusting the software settings.

1. Turn on the system and change the necessary BIOS settings, if any. See
Chapter 4 for information on BIOS setup.

2. Assign an IRQ to the card. Refer to the tables on the next page.

3. Install the software drivers for the expansion card.

When using PCI cards on shared slots, ensure that the drivers support “Share

IRQ” or that the cards do not need IRQ assignments. Otherwise, conicts will

arise between the two PCI groups, making the system unstable and the card
inoperable. Refer to the table on the next page for details.

• You do not need to clear the RTC when the system hangs due to CPU
overclocking. With the C.P.R. (CPU Parameter Recall) feature, shut down
and reboot the system so the BIOS can automatically reset CPU parameter
settings to default values. If the system hangs due to overclocking of
memory timing or chipset voltage and the power button fails to function,
pressing down the clr CMOS switch will shut down the system and clear
CMOS simultaneously.

4.1.5 ASUS CrashFree BIOS 3 utility

The ASUS CrashFree BIOS 3 is an auto recovery tool that allows you to restore

the BIOS le when it fails or gets corrupted during the updating process. You can
update a corrupted BIOS le using the motherboard support DVD, the oppy disk,
or the USB ash disk that contains the updated BIOS le.

Prepare the motherboard support DVD, the oppy disk or the USB ash disk

containing the updated motherboard BIOS before using this utility.

Recovering the BIOS from the support DVD

To recover the BIOS from the support DVD:

1. Turn on the system.

2. Insert the motherboard support DVD to the optical drive.

3. The utility displays the following message and automatically checks the DVD

for the BIOS le.

Bad BIOS checksum. Starting BIOS recovery...

Checking for oppy...

When found, the utility reads the BIOS le and starts ashing the corrupted

BIOS le.

Bad BIOS checksum. Starting BIOS recovery...
Checking for oppy...
Floppy found!
Reading le “Blitz Formula.ROM”. Completed.
Start ashing...

4. Restart the system after the utility completes the updating process.

Recovering the BIOS from the USB ash disk

To recover the BIOS from the USB ash disk:

1. Insert the USB ash disk that contains BIOS le to the USB port.

2. Turn on the system.

3. The utility will automatically checks the devices for the BIOS le When found,
the utility reads the BIOS le and starts ashing the corrupted BIOS le.

4. Restart the system after the utility completes the updating process.

• Only the USB ash disk with FAT 32/16 format and single partition can
support ASUS CrashFree BIOS 3. The device size should be smaller than

8GB.

• DO NOT shut down or reset the system while updating the BIOS! Doing so
can cause system boot failure!

4-8 Chapter 4: BIOS setup

4.2 BIOS setup program

This motherboard supports a programmable Serial Peripheral Interface (SPI) chip
that you can update using the provided utility described in section “4.1 Managing
and updating your BIOS.”

Use the BIOS Setup program when you are installing a motherboard, reconguring
your system, or prompted to “Run Setup.” This section explains how to congure

your system using this utility.

Even if you are not prompted to use the Setup program, you can change the

conguration of your computer in the future. For example, you can enable the

security password feature or change the power management settings. This

requires you to recongure your system using the BIOS Setup program so that the
computer can recognize these changes and record them in the CMOS RAM of the

SPI chip.

The SPI chip on the motherboard stores the Setup utility. When you start up the
computer, the system provides you with the opportunity to run this program. Press

<Del> during the Power-On Self-Test (POST) to enter the Setup utility; otherwise,

POST continues with its test routines.

If you wish to enter Setup after POST, restart the system by pressing
<Ctrl+Alt+Delete>, or by pressing the reset button on the system chassis. You can
also restart by turning the system off and then back on. Do this last option only if

the rst two failed.

The Setup program is designed to make it as easy to use as possible. Being a
menu-driven program, it lets you scroll through the various sub-menus and make
your selections from the available options using the navigation keys.

• The default BIOS settings for this motherboard apply for most conditions
to ensure optimum performance. If the system becomes unstable after
changing any BIOS settings, load the default settings to ensure system
compatibility and stability. Select the Load Setup Defaults item under the
Exit Menu. See section 4.9 Exit Menu.

• The BIOS setup screens shown in this section are for reference purposes
only, and may not exactly match what you see on your screen.

• Visit the ASUS website (www.asus.com) to download the latest BIOS le for

this motherboard.
