CAUTION!
1. Whether 1866/1600MHz memory speed is supported depends
on the AM3/AM3+ CPU you adopt. If you want to adopt DDR3
1866/1600 memory module on this motherboard, please refer
to the memory support list on our website for the compatible
memory modules.
ASRock website: http://www.asrock.com
2. Due to the operating system limitation, the actual memory size
may be less than 4GB for the reservation for system usage un-
der Windows®8.1 / 8 / 7 / VistaTM / XP. For Windows®64-bit OS
with 64-bit CPU, there is no such limitation.
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.

2. Installation
This is an ATX form factor motherboard. Before you install the motherboard, study
the conguration of your chassis to ensure that the motherboard 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
component.
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.

Step 1. Unlock the socket by lifting the lever up to a 90oangle.
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 ts in place.
The CPU 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 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. 3). For proper instal-
lation, please kindly refer to the instruction manuals of the CPU fan and
the heatsink.

2.3 Installation of Memory Modules (DIMM)
This motherboard provides four 240-pin DDR3 (Double Data Rate 3) DIMM slots,
and supports Dual Channel Memory Technology. For dual channel conguration,
you always need to install identical (the same brand, speed, size and chip-type)
DDR3 DIMM pair in the slots. In other words, you have to install identical DDR3
DIMM pair in Dual Channel (DDR3_A1 and DDR3_B1; Black slots; see p.2 No.6)
or identical DDR3 DIMM pair in Dual Channel (DDR3_A2 and DDR3_B2; Black
slots; see p.2 No.7), so that Dual Channel Memory Technology can be activated.
This motherboard also allows you to install four DDR3 DIMMs for dual channel
conguration, and please install identical DDR3 DIMMs in all four slots. You may
refer to the Dual Channel Memory Conguration Table below.
Dual Channel Memory Congurations

(Black Slot) (Black Slot) (Black Slot) (Black Slot)
(1) Populated - Populated -
(2) - Populated - Populated
(3)* Populated Populated Populated Populated
* For the conguration (3), please install identical DDR3 DIMMs in all four
slots.
1. Please install the memory module into the slots DDR3_A2 and
DDR3_B2 for the rst priority.
2. If you want to install two memory modules, for optimal compatibility
and reliability, it is recommended to install them either in the set of
slots DDR3_A1 and DDR3_B1, or in the set of slots DDR3_A2 and
DDR3_B2.
3. If only one memory module or three memory modules are installed
in the DDR3 DIMM slots on this motherboard, it is unable to activate
the Dual Channel Memory Technology.
4. If a pair of memory modules is NOT installed in the same Dual
Channel, for example, installing a pair of memory modules in
DDR3_A1 and DDR3_A2, it is unable to activate the Dual Channel
Memory Technology .
5. It is not allowed to install a DDR or DDR2 memory module into
DDR3 slot; otherwise, this motherboard and DIMM may be dam-
aged.
6. If you adopt DDR3 1866/1600 memory modules on this mother-
board, it is recommended to install them on DDR3_A2 and DDR3_
B2 slots.

Installing a DIMM
Please make sure to disconnect power supply before adding or
removing DIMMs or the system components.
Step 1. Unlock a DIMM slot by pressing the retaining clips outward.
Step 2. Align a DIMM on the slot such that the notch on the DIMM matches the
break on the slot.
The DIMM only ts in one correct orientation. It will cause permanent
damage to the motherboard and the DIMM if you force the DIMM into
the slot at incorrect orientation.
Step 3. Firmly insert the DIMM into the slot until the retaining clips at both ends
fully snap back in place and the DIMM is properly seated.

2.4 Expansion Slots (PCI and PCI Express Slots)
There are 2 PCI slots and 4 PCI Express slots on this motherboard.
PCI Slots: PCI slots are used to install expansion cards that have the 32-bit PCI
interface.
PCIE Slots:
PCIE1 / PCIE2 / PCIE4 (PCIE x1 slot; Black) is used for PCI Express
cards with x1 lane width cards, such as Gigabit LAN card and SATA2
card.
PCIE3 (PCIE x16 slot; Black) is used for PCI Express x16 lane width
graphics cards.
Installing an expansion card
Step 1. Before installing the expansion card, please make sure that the power
supply is switched off or the power cord is unplugged. Please read the
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
in a chassis).
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 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.

2.5 Jumpers Setup
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
Clear CMOS Jumper
(CLRCMOS1)
(see p.2, No. 38)
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 nish updating the BIOS, you must boot
up the system rst, and then shut it down before you do the clear-CMOS ac-
tion. Please be noted that the password, date, time, user default prole, 1394
GUID and MAC address will be cleared only if the CMOS battery is removed.

2.7 Untied Overclocking Technology
This motherboard supports Untied Overclocking Technology, which means during
overclocking, FSB enjoys better margin due to xed PCI / PCIE buses. Before you
enable Untied Overclocking function, please enter “Overclock Mode” option of BIOS
setup to set the selection from [Auto] to [Manual]. Therefore, CPU FSB is untied
during overclocking, but PCI / PCIE buses are in the xed mode so that FSB can
operate under a more stable overclocking environment.
Please refer to the warning on page 7 for the possible overclocking risk
before you apply Untied Overclocking Technology.
