1.1.2
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 are also available in FM2 socket compatible CPUs.
1.1.3
ASUS Exclusive Features
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.
*
ASUS Network iControl feature is not supported on Windows® XP/Vista operating systems.
Ai Charger
Ai Charger is ASUS fast-charging software that supports iPod, iPhone, and iPad.
*
Check your USB mobile device if it fully supports the BC 1.1 function.
** The actual charging speed may vary with your USB device’s conditions.
***Ai Charger is only supported when you set the USB device wake-up jumpers to +5VSB. See
section 1.7 Jumpers for details.
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:

Chapter 1: Product introduction
ASUS Anti-Surge Protection
This special design protects expensive devices and the motherboard from damage caused
by power surges from switching power supply unit (PSU).
AI Suite II
With its user interface, ASUS AI Suite II integrates several ASUS utilities and allows you to
launch and operate these utilities simultaneously. It allows you to configure the overclocking
settings, adjust the frequencies and related voltages, remotely control the system via a
mobile device, and other easy-to-use helpful utilities.
ASUS Fan Xpert
ASUS Fan Xpert intelligently allows you to adjust the CPU fan speed based on different
ambient temperatures, resulting to a quiet and cool computing environment.
ESD
Protect your computer with ESD Guards. Electrostatic discharge (ESD) conditions can
happen while plugging or unplugging any USB peripherals-causing damage to the computer.
ASUS ESD Guards clamp the ESD voltage and shunt the majority of the ESD current away
for a more reliable computing environment.
ASUS EZ Flash 2
ASUS EZ Flash 2 is a user-friendly utility that allows you to update the BIOS without using a
bootable floppy disk or an OS-based utility.
ASUS MyLogo2™
Turn your favorite photos into 256-color boot logos to personalize your system.
ASUS CrashFree BIOS 3
ASUS CrashFree BIOS 3 allows you to restore a corrupted BIOS file from a USB storage
device that contains the BIOS file.
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.

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.
Standby Power 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.
