WARNING

Please realize that there is a certain risk involved with overclocking, including

English

adjusting the setting in the BIOS, applying Untied Overclocking Technology, or

It should be done at your own risk and expense. We are not responsible for possible

damage caused by overclocking.

CAUTION!

1. Due to the chipset limitation, the actual memory size may be less than

®

4GB for the reservation for system usage under Windows

OS. You can

®

use ASRock XFast RAM to utilize the memory that Windows

cannot use.

2. 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 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.

3. 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

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 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.

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

performance may depend on the properties of the device.

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

the benets listed below. LAN Application Prioritization: You can con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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.

6. ASRock XFast RAM fully utilizes the memory space that cannot be used

®

under Windows

OS 32-bit CPU. ASRock XFast RAM shortens the load-

ing time of previously visited websites, making web surng 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-

English

pan.

7. 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 nish the BIOS update procedure after

regaining power. Please note that BIOS les need to be placed in the

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

8. Although this motherboard offers stepless control, it is not recommended

to perform over-clocking. Frequencies other than the recommended CPU

bus frequencies may cause instability of the system or damage the CPU.

9. 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.

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

European Union to dene the power consumption for the completed sys-

tem. 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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.
