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 over-
clocking 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. ASRock UCC (Unlock CPU Core) feature simpli es AMD CPU activa-
tion. As long as a simple switch of the UEFI option “ASRock UCC”, you
can unlock the extra CPU core to enjoy an instant performance boost.
When UCC feature is enabled, the dual-core or triple-core CPU will boost
to the quad-core CPU, and some CPU, including quad-core CPU, can
also increase L3 cache size up to 6MB, which means you can enjoy the
upgrade CPU performance with a better price. Please be noted that UCC
feature is supported with AM3 CPU only, and in addition, not every AM3
CPU can support this function because some CPU’s hidden core may be
malfunctioned.
2. This motherboard supports Untied Overclocking Technology. Please read
“Untied Overclocking Technology” on page 48 for details.
3. 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.
4. Whether 2100MHz memory speed is supported depends on the AM3/
AM3+ CPU you adopt. If you want to adopt DDR3 2100 memory module
on this motherboard, please refer to the memory support list on our web-
site for the compatible memory modules.
ASRock website http://www.asrock.com
5. Due to the operating system limitation, the actual memory size may be
®
less than 4GB for the reservation for system usage under Windows
7 /
TM
®
Vista
/ XP. For Windows
64-bit OS with 64-bit CPU, there is no such
limitation.
6. For microphone input, this motherboard supports both stereo and mono
modes. For audio output, this motherboard supports 2-channel, 4-chan-
nel, 6-channel, and 8-channel modes. Please check the table on page 13
for proper connection.
7. ASRock Extreme Tuning Utility (AXTU) is an all-in-one tool to ne-tune
different system functions in a user-friendly interface, which is including
Hardware Monitor, Fan Control, Overclocking, OC DNA and IES. In Hard-
ware Monitor, it shows the major readings of your system. In Fan Control,
it shows the fan speed and temperature for you to adjust. In Overclock-
ing, 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 with your friends. Your friends then can load the OC pro le to
9
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 com-
puting performance. Please visit our website for the operation procedures
of ASRock Extreme Tuning Utility (AXTU).
ASRock website: http://www.asrock.com
8. ASRock Instant Flash is a BIOS ash utility embedded in Flash ROM.
This convenient BIOS update tool allows you to update system BIOS
®
without entering operating systems rst 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 le to your USB ash drive, oppy disk or hard
drive, then you can update your BIOS only in a few clicks without prepar-
ing 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.
9. If you desire a faster, less restricted way of charging your Apple devices,
such as iPhone/iPod/iPad Touch, ASRock has prepared a wonderful so-
lution for you - ASRock APP Charger. Simply installing the APP Charger
driver, it makes your iPhone charged 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 than ever.
ASRock website: http://www.asrock.com/Feature/AppCharger/index.asp
10. ASRock XFast USB can boost USB storage device performance. The
performance may depend on the property of the device.
11. ASRock On/Off Play Technology allows users to enjoy the great audio ex-
perience from the portable audio devices, such like MP3 player or mobile
phone to your PC, even when the PC is turned off (or in ACPI S5 mode)!
This motherboard also provides a free 3.5mm audio cable (optional) that
ensures users the most convenient computing environment.
12. 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.
13. 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 sys-
tem.

14. EuP, stands for Energy Using Product, was a provision regulated by Eu-
ropean Union to de ne 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 ef ciency 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.
