This motherboard supports AMD® Socket AM3 multi-core processors with unique L3 cache and delivers better overclocking capabilities with less power consumption. It features dual-channel DDR3 1333 memory support and accelerates data transfer rate up to 5200MT/s via

HyperTransport™ 3.0-based system bus. This motherboard also supports

AMD® CPUs in the new 45nm manufacturing process.

AMD® 770 Chipset

The AMD® 770 Chipset is designed to support up to 5200MT/s HyperTransport™ 3.0 (HT 3.0) interface speed and PCI Express 2.0 x16 graphics. It is optimized with AMD’s latest AM3 multi-core CPUs to provide excellent system performance and overclocking capabilities.

HyperTransport™ 3.0 support

HyperTransport™ 3.0 technology provides 2.6 times more bandwidth than HT1.0 that radically improves system efficiency for a smoother and faster computing environment.

AMD® Cool ‘n’ Quiet Technology

This motherboard supports the AMD® Cool ‘n’ Quiet technology which monitors system operation and automatically adjusts CPU voltage and frequency for a cool and quiet operating environment.

DDR3 1800(O.C.) support

This motherboard supports DDR3 1800(O.C.)/1600(O.C.)/1333/ 1066MHz memory that features faster data transfer rates and more bandwidth to meet the requirements of the latest operation system, 3D graphics, multimedia, and Internet applications. The dual-channel DDR3 architecture doubles the bandwidth of your system memory to boost system performance, eliminating bottlenecks with peak bandwidth up to

25.6GB/s. Furthermore, the supply voltage for the memory is reduced from 1.8V for DDR2 to just 1.5V for DDR3. This voltage reduction limits the power consumption and heat generation of DDR3, which makes it an ideal memory solution.

PCI Express 2.0 support

This motherboard supports PCI Express 2.0 devices for double speed and bandwidth which enhances system performance.

Gigabit LAN solution

The onboard LAN controller is a highly integrated Gb LAN controller. It is enhanced with an ACPI management function to provide efficient power management for advanced operating systems.

Serial ATA 3Gb/s technology

This motherboard supports hard drives based on the Serial ATA (SATA)

3Gb/s storage specification, delivering enhanced scalability and doubling the bus bandwidth for high-speed data retrieval and save.

8-channel high definition audio

The onboard 8-channel HD audio (High Definition Audio, previously codenamed Azalia) CODEC enables high-quality 192KHz/24-bit audio output and jack-detect feature that automatically detects and identifies what types of peripherals are plugged into the audio I/O jacks and notifies users of inappropriate connection, which means there will be no more confusion of Line-in, Line-out, and Mic jacks.

1.3.2Innovative ASUS features

ASUS Express Gate

ASUS Express Gate is an instant-on environment that gives you quick access to the Internet. Five seconds after powering on your computer, you can instantly surf the Internet without entering the Windows® OS.

• ASUS Express Gate supports installation on SATA HDDs, USB HDDs and flash drives with at least 1.2GB free disk space. When installing it on USB HDDs or flash drives, connect the drives to the motherboard USB port before turning on the computer.

•The actual boot time depends on the system configuration.

•ASUS Express Gate supports file uploading from SATA HDDs, ODDs and USB drives. It supports file downloading to USB drives only.

•ASUS Express Gate complies with the OpenGL standard. Refer to support.asus.com for Express Gate source codes.

ASUS Turbo Key

ASUS Turbo Key allows you to turn the PC power button into an overclocking button. After the easy setup, Turbo Key boosts

performances without interrupting ongoing work or games, simply through pressing the button.

ASUS MyLogo2™

Turn your favorite photos into 256-color boot logos to personalize your system.

ASUS CrashFree BIOS 3

ASUS CrashFree BIOS 3 is an auto-recovery tool that allows you to restore a corrupted BIOS file using the bundled support DVD or a USB flash disk that contains the BIOS file.

ASUS EZ Flash 2

ASUS EZ Flash 2 allows you to update the BIOS from a USB flash disk before entering the OS.

ASUS Q-Fan

ASUS Q-Fan technology intelligently adjusts the CPU fan speed according to system loading to ensure a quiet, cool, and efficient operation.

ASUS EPU

ASUS EPU is a unique power saving technology that detects the current system loadings and adjusts the power consumption in real time.

ASUS AI NET2

ASUS AI NET2 remotely detects the cable connection immediately after you turn on the system and any faulty cable connections are reported back up to 100 meters at 1 meter accuracy.

C.P.R. (CPU Parameter Recall)

The BIOS C.P.R. feature automatically restores the CPU default settings when the system hangs due to overclocking failure. C.P.R. eliminates the need to open the system chassis and clear the RTC data. Simply shut down and reboot the system, and the BIOS automatically restores the CPU parameters to their default settings.

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.

1.4Before you proceed

Take note of the following precautions before you install motherboard components or change any motherboard settings.

• Unplug the power cord from the wall socket before touching any component.

•Before handling components, use a grounded wrist strap or touch a safely grounded object or a metal object, such as the power supply case, to avoid damaging them due to static electricity.

•Hold components by the edges to avoid touching the ICs on them.

•Whenever you uninstall any component, place it on a grounded antistatic pad or in the bag that came with the component.

•Before you install or remove any component, switch off the ATX power supply and detach its power cord. Failure to do so may cause severe damage to the motherboard, peripherals, or components.

Onboard LED

The motherboard comes with a standby power LED that lights up to indicate that the system is ON, in sleep mode, or in soft-off mode. This is a reminder that you should shut down

the system and unplug the power cable before removing or plugging in any motherboard component. The illustration below shows the location of the onboard LED.

1.5.1Placement direction

When installing the motherboard, ensure that you place it into the chassis in the correct orientation. The edge with external ports goes to the rear part of the chassis as indicated in the image below.

1.5.2Screw holes

Place six screws into the holes indicated by circles to secure the motherboard to the chassis.

DO NOT overtighten the screws! Doing so can damage the motherboard.

Place this side towards the rear of the chassis.

1.6Central Processing Unit (CPU)

This motherboard comes with an AM3 socket designed for Phenom™ II / Athlon™ II / Sempron™ 100 series processors.

The AM3 socket has a different pinout from the AM2+/AM2 socket. Ensure that you use a CPU designed for the AM3 socket. The CPU fits in only one correct orientation. DO NOT force the CPU into the socket to prevent bending the pins and damaging the CPU!

1.6.1Installing the CPU

To install a CPU:

1.Locate the CPU socket on the motherboard.

M4A77TD

Ensure that the socket lever is lifted up to a 90°-100° angle; otherwise, the CPU will not fit in completely.

3.Position the CPU above the socket such that the CPU corner with the gold triangle matches the socket corner with a small triangle.

4. Carefully insert the CPU into the socket until it fits in place.

The CPU fits only in one correct orientation.

DO NOT force the CPU into the socket to prevent bending the pins and damaging the CPU!
