 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 

50 of the “User Manual” in the support CD.

2. Intel

®

 Small Business Advantage is a customizable platform integrated 

with IT tools, which helps maximize employee productivity, PC perfor-

mance, and data security. There are applications including Software 

Monitor, PC Health Center, Data Backup & Restore, Energy Saver and 

USB Blocker.

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 16 for proper installation.

4.  Due to the operating system limitation, the actual memory size may be 

less than 4GB for the reservation for system usage under Windows

®

 7 / 

Vista

TM

 / 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.

5.  Only PCIE1 slot supports Gen 3 speed. 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.

6.  The maximum shared memory size is de

fi

 ned by the chipset vendor and 

is subject to change. Please check Intel

9.  ASRock Extreme Tuning Utility (AXTU) is an all-in-one tool to 

fi

 ne-tune 

different system functions in a user-friendly interface, which includes 

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

fi

 le  and 

share it with your friends. Your friends then can load the OC pro

fi

 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

fi

 ciency when the CPU cores are idle without sacri

fi

 cing com-

puting performance. Please visit our website for the operation procedures 

of ASRock Extreme Tuning Utility (AXTU).

10.  ASRock Instant Flash is a BIOS 

fl

 ash utility embedded in Flash ROM. 

This convenient BIOS update tool allows you to update system BIOS 

without entering operating systems 

fi

 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 

fi

 le to your USB 

fl

 ash drive, 

fl

 oppy disk or hard drive, then you can update your BIOS only in a few 

clicks without preparing an additional 

fl

 oppy diskette or other complicated 

fl

 ash utility. Please be noted that the USB 

fl

 ash drive or hard drive must 

use FAT32/16/12 

fi

 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 solu-

tion for you - ASRock APP Charger. Simply install the APP Charger driv-

er, 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 continu-

ous charging when your PC enters into Standby mode (S1), Suspend to 

RAM (S3), hibernation mode (S4) or power off (S5). With APP Charger 

driver installed, you can easily enjoy the marvelous charging experience.

start page for IE that combines your most visited web sites, your history, 

your Facebook friends and your real-time newsfeed into an enhanced 

view for a more personal Internet experience. ASRock motherboards are 

exclusively equipped with the ASRock SmartView utility that helps you

13.  ASRock XFast USB can boost USB storage device performance. The 

performance may depend on the properties of the device.

14.  ASRock XFast LAN provides a faster internet access, which includes 

the bene

fi

 ts listed below. LAN Application Prioritization: You can con

fi

 g-

ure your application’s priority ideally and/or add new programs. Lower 

Latency in Game: After setting online game’s priority higher, it can lower 

the latency in games. Traf

fi

 c Shaping: You can watch Youtube HD videos 

and download simultaneously. Real-Time Analysis of Your Data: With 

the status window, you can easily recognize which data streams you are 

transferring currently.

15.  ASRock XFast RAM is a new function that is included into ASRock Ex-

treme Tuning Utility (AXTU). It fully utilizes the memory space that cannot 

be used under Windows

®

 32-bit OS. ASRock XFast RAM shortens the 

loading time of previously visited websites, making web surfing faster 

than ever. And it also boosts the speed of Adobe Photoshop 5 times 

faster. Another advantage of ASRock XFast RAM is that it reduces the 

frequency of accessing your SSDs or HDDs in order to extend their lifes-

pan.

16.  ASRock Crashless BIOS allows users to update their BIOS without fear 

of failing. If power loss occurs during the BIOS update process, ASRock 

Crashless BIOS will automatically 

fi

 nish the BIOS update procedure after 

regaining power. Please note that BIOS 

fi

 les need to be placed in the 

root directory of your USB disk. Only USB2.0 ports support this feature.

17.  Administrators are able to establish an internet curfew or restrict internet 

access at speci

fi

 ed times via OMG. You may schedule the starting and 

ending hours of internet access granted to other users. In order to pre-

vent users from bypassing OMG, guest accounts without permission to 

modify the system time are required.

18.  Internet Flash searches for available UEFI 

fi

 rmware updates from our 

servers. In other words, the system can auto-detect the latest UEFI from 

our servers and 

fl

 ash them without entering Windows OS. Please note 

that you must be running on a DHCP con

fi

 gured computer in order to en-

able this function.

19.  Users may prevent motherboard damages due to dampness by enabling 

“Dehumidi

fi

 er Function”. When enabling Dehumidi

fi

 er Function, the com-

puter will power on automatically to dehumidify the system after entering 

S4/S5 state.

20.  While CPU overheat is detected, the system will automatically shutdown.

Before you resume the system, please check if the CPU fan on the moth-

erboard 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.

21.  Combo Cooler Option (C.C.O.) provides the 

fl

 exible option to adopt three 

different CPU cooler types, Socket LGA 775, LGA 1155 and LGA 1156. 

Please be noticed that not all the 775 and 1156 CPU Fan can be used.

23.  EuP stands for Energy Using Product, was a provision regulated by the 

European Union to define the power consumption for the completed 

system. According to EuP, the total AC power of the completed system 

should be under 1.00W in off mode condition. To meet EuP standards, 

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, and the standby power ef

fi

 ciency should be higher 

than 50% under 100 mA current consumption. For EuP ready power sup-

ply selection, we recommend you to check with the power supply manu-

facturer for more details.
