CAUTION!

1. About the settings of “Hyper Threading Technology”, please chec

k page

43.

2. This motherboard supports Dual Channel Memory Technology. Before

you implement Dual Channel Memory Technology, make sure to read the

installation guide of memory modules on page 20 for proper installation.

3. Due to the operating system limitation, the actual memory size may be

less than 4GB for the reservation for system usage under Windows

7 /

OS with 64-bit CPU, there is no such limita-

tion. You can use ASRock XFast RAM to utilize the memory that Win-

dows

cannot use.

4. To run the PCI Express in Gen 3 speed, please install an Ivy Bridge CPU.

If you install a Sandy Bridge CPU, the PCI Express will run only at PCI

Express Gen 2 speed.

Make sure to unplug the power cord before installing or removing the

motherboard. Failure to do so may cause physical injuries to you and

damages to motherboard components.

2.2 Pre-installation Precautions

Take note of the following precautions before you install motherboard components

or change any motherboard settings.

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

components.

electricity, 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 the 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-

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.

1155-Pin Socket Overview

2.3 CPU Installation

In order to provide the LGA 1155 CPU sock-

ets more protection and make the instal-

lation process easier, ASRock has added

a new protection cover on top of the load

plate to replace the former PnP caps that

were under the load plate. For the installa-

tion of Intel

1155-Pin CPUs with the new

protection cover, please follow the steps

below.

Before you insert the 1155-Pin CPU into the socket, please check if the

CPU surface is unclean or if there are any bent pins in the socket. Do

not force to insert the CPU into the socket if above situation is found.

Otherwise, the CPU will be seriously damaged.

Step 1. Open the socket:

Step 1-1. Disengage the lever by pressing it

down and sliding it out of the hook.

You do not have to remove the pro-

tection cover.

Step 1-2. Keep the lever positioned at about

135 degrees in order to flip up the

load plate.

Step 2. Insert the 1155-Pin CPU:

Step 2-1. Hold the CPU by the edge which is

marked with a black line.

Step 2-2. Orient the CPU with the IHS (Inte-

and the two orientation key notches.

For proper installation, please ensure to match the two orientation

key notches of the CPU with the two alignment keys of the socket.

Step 2-3. Carefully place the CPU into the

socket.

Step 2-4. Verify that the CPU is within the sock-

et and properly mated to the orient

keys.

Step 3. Close the socket:

Step 3-1. Flip the load plate onto the IHS.

Step 3-2. Press down the load lever, and se-

cure it with the load plate tab under

the retention tab. The protection

cover will automatically come off by

itself.

Please save and replace the cover if the processor is removed. The

cover must be placed if you wish to return the motherboard for after

service.

2.4 Installation of CPU Fan and Heatsink

This motherboard is equipped with 1155-Pin socket that supports Intel 1155-Pin

CPUs. Please adopt the type of heatsink and cooling fan compliant with Intel 1155-

Pin CPU to dissipate heat. Before you install the heatsink, you need to spray ther-

mal interface material between the CPU and the heatsink to improve heat dissipa-

tion. Ensure that the CPU and the heatsink are securely fastened and in good con-

tact with each other. Then connect the CPU fan to the CPU_FAN connector (CPU_

For proper installation, please kindly refer to the instruction manuals of your

CPU fan and heatsink.

Step 3. Align fasteners with the motherboard through-

holes.

Step 4. Rotate the fastener clockwise, then press

down on fastener caps with thumb to install

and lock. Repeat with remaining fasteners.

If you press down the fasteners without rotating them clockwise, the

heatsink cannot be secured on the motherboard.

Step 5. Connect fan header with the CPU fan connector on the motherboard.

Step 6. Secure redundant cable with tie-wrap to ensure the cable does not

interfere with fan operation or contact other components.

2. If you install only one memory module or two non-identical

memory modules, it is unable to activate the Dual Channel

Memory Technology.

3. Some DDR3 1GB double-sided DIMMs with 16 chips may not

work on this motherboard. It is not recommended to install them

on this 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.
