1.3  Unique Features

ASRock Extreme Tuning Utility (AXTU)

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

ne-tune different system functions in a user-friendly interface, 

which includes Hardware Monitor, Fan Control, Overclocking, 

OC DNA, IES and XFast RAM. 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 

performance. 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 set-

tings. 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 computing per-

formance. In XFast RAM, it fully utilizes the memory space that 

cannot be used under Windows

®

 OS 32-bit CPU.

ASRock Instant Boot

ASRock Instant Boot allows you to turn on your PC in just a few 

seconds, provides a much more ef

fi

 cient way to save energy, 

time, money, and improves system running speed for your sys-

tem. It leverages the S3 and S4 ACPI features which normally 

enable the Sleep/Standby and Hibernation modes in Windows

®

to shorten boot up time. By calling S3 and S4 at speci

fi

 c timing 

during the shutdown and startup process, Instant Boot allows 

you to enter your Windows

®

 desktop in a few seconds.  

ASRock Instant Flash

ASRock Instant Flash is a BIOS 

fl

 ash utility embedded in Flash 

ROM. This convenient BIOS update tool allows you to update

. 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 compli-

cated 

fl

 ash utility. Please be noted that the USB 

fl

 ash drive or 

hard drive must use FAT32/16/12 

fi

 le system.
