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

1.1.2
ASUS Digital power Design
DIGI+ POWER CONTROL: Digital Power Design for the APU
ASUS motherboards using the AMD® A55 chipset employ precise digital voltage regulation
for the APU, called DIGI+VRM (Voltage Regulation Modules) digital power design. The
APU voltage and VRM Frequency are 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 energy 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 multi-tasking. Engineered and tested to
assure unimitigated performance, ASUS A55 boards with DIGI+ VRM remain efficient and
accurate, for reliable application in every scenario.
*DIGI+ VRM functions also available in FM2 socket compatible CPUs.

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.
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.
