ASRock A55 Pro3: 2. Installation
2. Installation: ASRock A55 Pro3

2. Installation
This is an ATX form factor (12.0-in x 8.6-in, 30.5 cm x 21.8 cm) motherboard.
Before you install the motherboard, study the conguration 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.

2.1 CPU Installation
o
Step 1. Unlock the socket by lifting the lever up to a 90
angle.
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. 5 or CPU_FAN2, see
Page 2, No. 6). For proper installation, please kindly refer to the instruc-
tion 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 of the same color. In other words,
you have to install identical DDR3 DIMM pair in Dual Channel A (DDR3_A1
and DDR3_B1; Blue slots; see p.2 No.7) or identical DDR3 DIMM pair in Dual
Channel B (DDR3_A2 and DDR3_B2; White slots; see p.2 No.8), so that Dual
Channel Memory Technology can be activated. This motherboard also allows
you to install four DDR3 DIMMs for dual channel conguration, and please in-
stall identical DDR3 DIMMs in all four slots. You may refer to the Dual Channel
Memory Conguration Table below.
Dual Channel Memory Congurations
DDR3_A1 DDR3_A2 DDR3_B1 DDR3_B2
(Blue Slot) (White Slot) (Blue Slot) (White Slot)
(1) Populated - Populated -
(2) - Populated - Populated
(3)* Populated Populated Populated Populated
*
For the conguration (3), please install identical DDR3 DIMMs in all four
slots.
1. If you want to install two memory modules, for optimal compatibility
and reliability, it is recommended to install them in the slots of the
same color. In other words, install them either in the set of blue
slots (DDR3_A1 and DDR3_B1), or in the set of white slots (DDR3_
A2 and DDR3_B2).
2. 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.
3. 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 .
English
4. It is not allowed to install a DDR or DDR2 memory module into
DDR3 slot; otherwise, this motherboard and DIMM may be dam-
aged.
5. If you adopt DDR3 2400/1866/1600 memory modules on this
motherboard, it is recommended to install them on DDR3_A2 and
DDR3_B2 slots.
14
ASRock A55 Pro3 Motherboard

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 3 PCI slots and 3 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 (PCIE x1 slot; White) is used for PCI Express cards with x1 lane
width cards, such as Gigabit LAN card and SATA2 card.
PCIE2 (PCIE x16 slot; Blue) is used for PCI Express x16 lane width
graphics cards, or used to install PCI Express graphics cards to support
TM
CrossFireX
function.
PCIE3 (PCIE x16 slot; Blue) is used for PCI Express x4 lane width
cards, or used to install PCI Express graphics cards to support
TM
CrossFireX
function.
1. In single VGA card mode, it is recommended to install a PCI Ex-
press x16 graphics card on PCIE2 slot.
TM
2. In CrossFireX
mode, please install PCI Express x16 graphics
cards on PCIE2 and PCIE3 slots. Therefore, PCIE2 slot will work at
x16 bandwidth while PCIE3 slot will work at x4 bandwidth.
3. Please connect a chassis fan to motherboard chassis fan connec-
tor (CHA_FAN1, CHA_FAN2 or CHA_FAN3) when using multiple
graphics cards for better thermal environment.
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.
English
Step 5. Fasten the card to the chassis with screws.
Step 6. Replace the system cover.

Surround Display Feature
This motherboard supports surround display upgrade. With the internal VGA output
support (D-Sub and HDMI) and external add-on PCI Express VGA cards, you can
easily enjoy the benets of surround display feature.
Please refer to the following steps to set up a surround display environment:
1. Install the PCI Express VGA cards on PCIE2 and PCIE3 slots. Please refer to
page 16 for proper expansion card installation procedures for details.
2. Connect D-Sub monitor cable to D-Sub port on the I/O panel, or connect HDMI

HDCP Function
HDCP function is supported on this motherboard. To use HDCP
function with this motherboard, you need to adopt the monitor
that supports HDCP function as well. Therefore, you can enjoy
the superior display quality with high-denition HDCP
encryption contents. Please refer to below instruction for more
details about HDCP function.
What is HDCP?
HDCP stands for High-Bandwidth Digital Content Protection,
®
a specication developed by Intel
for protecting digital
entertainment content that uses the DVI interface. HDCP is a
copy protection scheme to eliminate the possibility of
intercepting digital data midstream between the video source,
or transmitter - such as a computer, DVD player or set-top box -
and the digital display, or receiver - such as a monitor, television
or projector. In other words, HDCP specication is designed to
protect the integrity of content as it is being transmitted.
Products compatible with the HDCP scheme such as DVD
players, satellite and cable HDTV set-top-boxes, as well as few
entertainment PCs requires a secure connection to a compliant
English
display. Due to the increase in manufacturers employing HDCP
in their equipment, it is highly recommended that the HDTV or
LCD monitor you purchase is compatible.
