ASRock FM2A75M-DGS: 2. Installation

2. Installation: ASRock FM2A75M-DGS

2. Installation

This is a Micro ATX form factor (8.9-in x 7.6-in, 22.6 cm x 19.3 cm) 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.

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. 4). 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 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.

1. It is not allowed to install a DDR or DDR2 memory module into

DDR3 slot;otherwise, this motherboard and DIMM may be

damaged.

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

memory modules, it is unable to activate the Dual Channel

Memory Technology.

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.

notch

break

notch

break

The DIMM only ts in one correct orientation. It will cause permanent

English

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 is 1 PCI slot and 2 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 x16 slot) is used for PCI Express x16 lane width graphics

cards.

PCIE2 (PCIE x1 slot) is used for PCI Express cards with x1 lane width

cards, such as Gigabit LAN card and SATA2 card.

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. 30)

Clear CMOSDefault

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.
