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
third-party overclocking tools. Overclocking may affect your system’s 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. About the settings of “Hyper Threading Technology”, please check page
43 of the “User Manual” in the support CD.
2. This motherboard supports Dual Channel Memory Technology. Before
you implement Dual Channel Memory Technology, make sure to read the
installation guide of memory modules on page 17 for proper installation.
3. Due to the operating system limitation, the actual memory size may be
less than 4GB for the reservation for system usage under Windows®7 /
VistaTM / XP. For Windows®OS with 64-bit CPU, there is no such limita-
tion. You can use ASRock XFast RAM to utilize the memory that Win-
dows®cannot use.
4. To run the PCI Express in Gen 3 speed, please install an Ivy Bridge CPU.
If you install a Sandy Bridge CPU, the PCI Express will run only at PCI
Express Gen 2 speed.
5. The maximum shared memory size is dened by the chipset vendor and
is subject to change. Please check Intel®website for the latest informa-
tion.
6. You can choose to use two of the three monitors only. D-Sub, DVI-D and
HDMI monitors cannot be enabled at the same time. Besides, with the
DVI-to-HDMI adapter, the DVI-D port can support the same features as
HDMI port.

9. ASRock Extreme Tuning Utility (AXTU) is an all-in-one tool to ne-tune dif-
ferent system functions in a user-friendly interface, which includes Hard-
ware Monitor, Fan Control, Overclocking, OC DNA and IES. In Hardware
Monitor, it shows the major readings of your system. In Fan Control, it
shows the fan speed and temperature for you to adjust. In Overclocking,
you are allowed to overclock CPU frequency for optimal system per-
formance. In OC DNA, you can save your OC settings as a prole and
share it with your friends. Your friends then can load the OC prole to
their own system to get the same OC settings. In IES (Intelligent Energy
Saver), the voltage regulator can reduce the number of output phases to
improve efciency when the CPU cores are idle without sacricing
computing performance. Please visit our website for the operation proce-
dures of ASRock Extreme Tuning Utility (AXTU).
ASRock website: http://www.asrock.com

without entering operating systems rst like MS-DOS or Windows®. With
this utility, you can press the <F6> key during the POST or the <F2>
key to enter into the BIOS setup menu to access ASRock Instant Flash.
Just launch this tool and save the new BIOS le to your USB ash drive,
oppy disk or hard drive, then you can update your BIOS only in a few
clicks without preparing an additional oppy diskette or other complicated
ash utility. Please be noted that the USB ash drive or hard drive must
use FAT32/16/12 le system.
11. If you desire a faster, less restricted way of charging your Apple devices,
such as iPhone/iPad/iPod Touch, ASRock has prepared a wonderful so-
lution for you - ASRock APP Charger. Simply install the APP Charger
driver, it makes your iPhone charge much quickly from your computer
and up to 40% faster than before. ASRock APP Charger allows you to
quickly charge many Apple devices simultaneously and even supports
continuous charging when your PC enters into Standby mode (S1), Sus-
pend to RAM (S3), hibernation mode (S4) or power off (S5). With APP
Charger driver installed, you can easily enjoy the marvelous charging
experience.
