WARNING
Please realize that there is a certain risk involved with overclocking, including adjusting
the setting in the BIOS, applying Untied Overclocking Technology, or using the third-
party overclocking tools. Overclocking may affect your system stability, or even
cause damage to the components and devices of your system. It should be done at
your own risk and expense. We are not responsible for possible damage caused by
overclocking.
CAUTION!
1. This motherboard supports Untied Overclocking Technology. Please read
“Untied Overclocking Technology” on page 24 for details.
2. The maximum shared memory size is defined by the chipset vendor and
is subject to change. Please checkAMDwebsite for the latest information.
3. Before installing SATAII hard disk to SATAII connector, please read the “SATAII
Hard Disk Setup Guide” on page 26 of “User Manual” in the support CD to
adjust your SATAII hard disk drive to SATAII mode. You can also connect SATA
hard disk to SATAII connector directly.
4. Power Management for USB 2.0 works fine under Microsoft®Windows® 7
64-bit / 7 / VistaTM 64-bit / VistaTM / XP 64-bit / XP SP1 or SP2.
5. It is a user-friendly ASRock overclocking tool which allows you to surveil
your system by hardware monitor function and overclock your hardware
devices to get the best system performance under Windows® environment.
Please visit our website for the operation procedures of ASRock OC
Tuner. ASRock website: http://www.asrock.com
6. Featuring an advanced proprietary hardware and software design,
Intelligent Energy Saver is a revolutionary technology that delivers
unparalleled power savings. The voltage regulator can reduce the
number of output phases to improve efficiency when the CPU cores are
idle. In other words, it is able to provide exceptional power saving and
improve power efficiency without sacrificing computing performance. To
use Intelligent Energy Saver function, please enable Cool ‘n’ Quiet option
in the BIOS setup in advance. Please visit our website for the operation
procedures of Intelligent Energy Saver.

7. ASRock Instant Flash is a BIOS flash utility embedded in Flash ROM.
This convenient BIOS update tool allows you to update system BIOS
without entering operating systems first like MS-DOS or Windows®. With
this utility, you can press <F6> key during the POST or press <F2> key to
BIOS setup menu to access ASRock Instant Flash. Just launch this tool
and save the new BIOS file to your USB flash drive, floppy disk or hard
drive, then you can update your BIOS only in a few clicks without prepar-
ing an additional floppy diskette or other complicated flash utility. Please
be noted that the USB flash drive or hard drive must use FAT32/16/12 file
system.
8. The software name itself – OC DNA literally tells you what it is capable of.
OC DNA, an exclusive utility developed by ASRock, provides a conve-
nient way for the user to record the OC settings and share with others. It
helps you to save your overclocking record under the operating system
and simplifies the complicated recording process of overclocking settings.
With OC DNA, you can save your OC settings as a profile and share with
your friends! Your friends then can load the OC profile to their own system
to get the same OC settings as yours! Please be noticed that the OC
profile can only be shared and worked on the same motherboard.
9. Although this motherboard offers stepless control, it is not recommended
to perform over-clocking. Frequencies other than the recommended CPU
bus frequencies may cause the instability of the system or damage the
CPU.
10. While CPU overheat is detected, the system will automatically shutdown.
Before you resume the system, please check if the CPU fan on the
motherboard functions properly and unplug the power cord, then plug it
back again. To improve heat dissipation, remember to spray thermal
grease between the CPU and the heatsink when you install the PC system.
11. EuP, stands for Energy Using Product, was a provision regulated by
European Union to define the power consumption for the completed system.
According to EuP, the total AC power of the completed system shall be
under 1.00W in off mode condition. To meet EuP standard, an EuP ready
motherboard and an EuP ready power supply are required. According to
Intel’s suggestion, the EuP ready power supply must meet the standard of
5v standby power efficiency is higher than 50% under 100 mA current
consumption. For EuP ready power supply selection, we recommend you
checking with the power supply manufacturer for more details.

Pre-installation Precautions
Take note of the following precautions before you install mother-
board components or change any motherboard settings.
1. Unplug the power cord from the wall socket before touching any
component. Failure to do so may cause severe damage to the
motherboard, peripherals, and/or components.
2. To avoid damaging the motherboard components due to static
electricity, NEVER place your motherboard directly on the car-
pet or the like. Also remember to use a grounded wrist strap or
touch a safety grounded object before you handle components.
3. Hold components by the edges and do not touch the ICs.
4. Whenever you uninstall any component, place it on a
grounded antstatic pad or in the bag that comes with the
component.
5. When placing screws into the screw holes to secure the
motherboardtothechassis, please do not over-tighten the screws!
Doing so may damage the motherboard.

HDCP Function
HDCP function is supported on this motherboard. To use HDCP
function with this motherboard, you need to adopt the monitor that
supports HDCP function as well. Therefore, you can enjoy the
superior display quality with high-definition HDCP encryption
contents. Please refer to below instruction for more details about
HDCP function.
What is HDCP?
HDCP stands for High-Bandwidth Digital Content Protection, a
specification developed by Intel®for protecting digital entertainment
content that uses the DVI interface. HDCP is a copy protection
scheme to eliminate the possibility of intercepting digital data
midstream between the video source, or transmitter - such as a
computer, DVD player or set-top box - and the digital display, or
receiver - such as a monitor, television or projector. In other words,
HDCP specification is designed to protect the integrity of content as it
is being transmitted.
Products compatible with the HDCP scheme such as DVD players,
satellite and cable HDTV set-top-boxes, as well as few entertain-
ment PCs requires a secure connection to a compliant display. Due
to the increase in manufacturers employing HDCP in their equipment,
it is highly recommended that the HDTV or LCD monitor you purchase
is compatible.
