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 profi le and share it with your friends. Your friends then can

load the OC profi 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 effi ciency

when the CPU cores are idle without sacrifi cing computing per-

XFast RAM, it fully utilizes the memory space that

cannot be used under Windows

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

seconds, provides a much more effi 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 specifi 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

system BIOS without entering operating systems fi rst like MS-

. 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.9

If you desire a faster, less restricted way of charging your

Apple devices, such as iPhone/iPad/iPod Touch, ASRock has

prepared a wonderful solution 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 mar-

velous charging experience.

ASRock XFast LAN ASRock XFast LAN provides a faster internet access, which

includes the benefits listed below. LAN Application Prioritiza-

tion: You can confi gure 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. Traffi c

Shaping: You can watch Youtube HD videos and download si-

multaneously. Real-Time Analysis of Your Data: With the status

window, you can easily recognize which data streams you are

transferring currently.

ASRock XFast RAM ASRock XFast RAM is a new function that is included into AS-

Rock Extreme Tuning Utility (AXTU). It fully utilizes the memory

space that cannot be used under Windows

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. An-

other advantage of ASRock XFast RAM is that it reduces the

frequency of accessing your SSDs or HDDs in order to extend

without fear of failing. If power loss occurs during the BIOS up-

date 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.

ASRock OMG (Online Management Guard)

Administrators are able to establish an internet curfew or restrict

ASRock FM2A55 Pro Motherboard

This is an ATX form factor motherboard. Before you install the motherboard, study

the confi guration of your chassis to ensure that the motherboard fi ts into it.

Pre-installation Precautions

Take note of the following precautions before you install motherboard

components or change any motherboard settings.

Before you install or remove any component, ensure that the

power is switched off or the power cord is detached from the

power supply. Failure to do so may cause severe damage to the

motherboard, peripherals, and/or components.

1. Unplug the power cord from the wall socket before touching any

2. To avoid damaging the motherboard components due to static elec-

tricity, NEVER place your motherboard directly on the carpet or the

like. Also remember to use a grounded wrist strap or touch a safety

grounded object before you handle components.

3. Hold components by the edges and do not touch the ICs.

4. Whenever you uninstall any component, place it on a grounded anti-

static pad or in the bag that comes with the component.

5. When placing screws into the screw holes to secure the mother-

board to the chassis, please do not over-tighten the screws! Doing

so may damage the motherboard.

2.1 CPU Installation

Step 1. Unlock the socket by lifting the lever up to a 90

Step 2. Position the CPU directly above the socket such that the CPU corner with

the golden triangle matches the socket corner with a small triangle.

Step 3. Carefully insert the CPU into the socket until it fi ts in place.

The CPU fi ts only in one correct orientation. DO NOT force the CPU

into the socket to avoid bending of the pins.

Step 4. When the CPU is in place, press it fi rmly on the socket while you push

down the socket lever to secure the CPU. The lever clicks on the side tab

to indicate that it is locked.

2.2 Installation of CPU Fan and Heatsink

After you install the CPU into this motherboard, it is necessary to install a

larger heatsink and cooling fan to dissipate heat. You also need to spray

thermal grease between the CPU and the heatsink to improve heat dis-

sipation. Make sure that the CPU and the heatsink are securely fastened

and in good contact with each other. Then connect the CPU fan to the

CPU FAN connector (CPU_FAN1, see Page 2, No. 4). For proper instal-

lation, please kindly refer to the instruction manuals of the CPU fan and

2.3 Installation of Memory Modules (DIMM)

This motherboard provides two 240-pin DDR3 (Double Data Rate 3) DIMM slots,

and supports Dual Channel Memory Technology. For dual channel configuration,

you always need to install two identical (the same brand, speed, size and chip-

type) memory modules in the DDR3 DIMM slots to activate Dual Channel Memory

Technology. Otherwise, it will operate at single channel mode.

documentation of the expansion card and make necessary hardware

settings for the card before you start the installation.

Step 2. Remove the system unit cover (if your motherboard is already installed

Step 3. Remove the bracket facing the slot that you intend to use. Keep the

screws for later use.

Step 4. Align the card connector with the slot and press fi rmly until the card is

completely seated on the slot.

Step 5. Fasten the card to the chassis with screws.

Step 6. Replace the system cover.16

2.6 Pin Header Easy Installation Guide

ASRock motherboard is equipped with pin headers with obvious colors which indi-

cate you to recognize the crucial headers more easily. Please refer to below illustra-

tions for the pin defi nition of onboard headers. If you want to have more information

about the usage of these headers, please refer to “Jumpers Setup“ and “Onboard

Headers and Connectors“ for details.

The illustration shows how jumpers are

setup. When the jumper cap is placed on

pins, the jumper is “Short”. If no jumper cap

is placed on pins, the jumper is “Open”. The

illustration shows a 3-pin jumper whose

pin1 and pin2 are “Short” when jumper cap

is placed on these 2 pins.

Jumper Setting Description

Note: CLRCMOS1 allows you to clear the data in CMOS. To clear and reset the

system parameters to default setup, please turn off the computer and unplug

the power cord from the power supply. After waiting for 15 seconds, use a

jumper cap to short pin2 and pin3 on CLRCMOS1 for 5 seconds. However,

please do not clear the CMOS right after you update the BIOS. If you need

to clear the CMOS when you just fi nish updating the BIOS, you must boot

up the system fi rst, and then shut it down before you do the clear-CMOS ac-

tion. Please be noted that the password, date, time, user default profi le, 1394

GUID and MAC address will be cleared only if the CMOS battery is removed.
