Safety information  
Electrical safety  
To prevent electrical shock hazard, disconnect the power cable from the electrical outlet  
before relocating the system.  
When adding or removing devices to or from the system, ensure that the power cables  
for the devices are unplugged before the signal cables are connected. If possible,  
disconnect all power cables from the existing system before you add a device.  
Before connecting or removing signal cables from the motherboard, ensure that all  
power cables are unplugged.  
Seek professional assistance before using an adapter or extension cord. These devices  
could interrupt the grounding circuit.  
Ensure that your power supply is set to the correct voltage in your area. If you are not  
sure about the voltage of the electrical outlet you are using, contact your local power  
company.  
If the power supply is broken, do not try to fix it by yourself. Contact a qualified service  
technician or your retailer.

cables are not damaged. If you detect any damage, contact your dealer immediately.  
To avoid short circuits, keep paper clips, screws, and staples away from connectors,  
slots, sockets and circuitry.  
Avoid dust, humidity, and temperature extremes. Do not place the product in any area  
where it may become wet.  
Place the product on a stable surface.

Product highlights  
1.1.1  
AMD® A-series and AthlonTM Series Processors  
This motherboard supports AMD® A- series and AthlonTM Series Processors. This  
revolutionary APU (Accelerated Processing Unit) combines processing power and advanced  
DirectX 11 graphics in one small, energy-efficient design to enable accelerated performance  
and an industry-leading visual experience. It features Dual-channel DDR3 memory support  
and accelerates data transfer rate up to 5GT/s.  
AMD® A85X FCH (Hudson D4) Chipset  
AMD® A85X FCH (Hudson D4) is designed to support up to 5GT/s interface speed and AMD  
CrossFireXTM. It supports 8 x SATA 6.0Gb/s ports and 4 x USB 3.0 ports.  
AMD® CrossFireX™ Technology  
AMD’s CrossFireX™ boosts image quality along with rendering speed, eliminating the  
need to scale down screen resolution to get high quality images. CrossFireX™ allows  
higher antialiasing, anisotropic filtering, shading, and texture settings. Adjust your display  
configurations, experiment with the advanced 3D settings, and check the effects with a real-  
time 3D-rendered previews within AMD Catalyst™ Control Center.  
Dual-Channel DDR3 2400 (O.C.)/2250 (O.C.)/2200 (O.C.)/2133 (O.C.)/2000  
(O.C.)/1866/1600/1333/1066MHz support  
The motherboard supports DDR3 memory that features data transfer rates of 2400(O.C.)  
/2250(O.C.) /2200(O.C.) /2133(O.C.) /2000(O.C.) /1866/1600/1333/1066 MHz to boost the  
system’s performance, and to meet the higher bandwidth requirements of the latest 3D  
graphics, multimedia, and Internet applications.  
Complete USB 3.0 integration  
This motherboard offers you the strategic USB 3.0 accessibility for both the front and rear  
panels, allowing you to experience the convenience of the latest plug and play connectivity  
solution at speed up to ten times faster than USB 2.0.  
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.

DIGI+VRM Digital Power Design  
DIGI+ POWER CONTROL: Digital Power Design for the APU*  
ASUS motherboards using the AMD® A85X chipset employ precise digital regulation for  
the APU, called DIGI+ VRM (Vloltage Regulation Modules) digital power design. The APU  
voltage is adjusted via either carefully developed automated modes, or by using user-defined  
profiles. The effect is that DIGI+ VRM technology ensures greater energy efficiency and the  
most precise power delivery. Boosetd by world-renowned ASUS quality, it creates an ideal  
computing platform for a diverse range of applications, from gaming to multimedia or office  
work and heavy multitasking. Engineered and tested to assure unmitigated performance,  
ASUS A85X boards with DIGI+ VRM remain efficient and accurate, for reliable application in  
every scenario.  
* DIGI+ VRM functions are also available in FM2 socket compatible CPUs.  
ASUS EPU  
EPU (Energy Processing Unit), the world’s first real-time system power-saving chip,  
automatically detects the current system load and intelligently moderates power usage.  
It offers a total system-wide energy optimization, reduces fan noise, and extends the  
component’s lifespan.  
1.1.3  
Innovative ASUS features  
ASUS UEFI BIOS (EZ Mode)  
ASUS UEFI BIOS, a UEFI compliant architecture, offers the first mouse-controlled intuitive  
graphical BIOS interface that goes beyond the traditional keyboard-only BIOS controls,  
providing you with more flexibility, convenience, and easy to navigate EFI BIOS than the  
traditional BIOS versions. It offers you with dual selectable modes and native support for hard  
drives larger than 2.2 TB.  
ASUS UEFI BIOS includes the following new features:  
F12 BIOS snapshot hotkey  
F3 Shortcut for most accessed information  
ASUS DRAM SPD (Serial Presence Detect) information detecting faulty DIMMs, and  
helping with difficult POST situations.

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.  
ErP ready  
The motherboard is European Union´s Energy-related Products (ErP) ready, and ErP  
requires products to meet certain energy efficiency requirements in regards to energy  
consumptions. This is in line with ASUS vision of creating environment-friendly and energy-  
efficient products through product design and innovation to reduce carbon footprint of the  
product and thus mitigate environmental impacts.

Chapter 1: Product introduction  
1.2  
Before 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, ensure that the ATX power supply is  
switched off or the power cord is detached from the power supply. Failure to do so  
may cause severe damage to the motherboard, peripherals, or components.
