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

ASUS DIGI+ VRM
DIGI+POWER CONTROL: Digital Power Design for the APU*
ASUS motherboards using the AMD® A85X chipset employ precise digital voltage regulation
for the APU, called DIGI+ VRM (Voltage 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. Boosted 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 also available in FM2 socket compatible CPUs
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
ASUS Exclusive Features
USB 3.0 Boost
With USB 3.0 Boost technology, USB transfer speeds are significantly increased up to
132%, enhancing an already impressive USB 3.0 transfer rate. ASUS software automatically
accelerates data speeds for compatible USB 3.0 peripherals without the need for any further
user interaction.
Remote GO!
Remote GO! links PCs, tablets, smartphones and TVs wirelessly together through an existing
LAN cable and router setup. It allows users to stream multimedia content from PC to DLNA
devices, access their computer anywhere using their mobile device at home, while also

Chapter 1: Product introduction
Network iControl
Network iControl is an intuitive one-step network control center that makes it easier for you to
manage your bandwidth and allows you to set, monitor, and schedule the bandwidth priorities
for your network programs. It allows you to automatically connect to a PPPoE network for a
more convenient online experience.
*
The ASUS Network iControl feature does not support Windows® XP/Vista operating systems.
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,

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.
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, 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.
