ASRock FM2A75M-ITX R2.0: 2. Installation

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 Slot (PCI Express Slot)

There is 1 PCI Express slot on this motherboard.

PCIE Slot: PCIE1 (PCIE x16 slot) 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. 23)

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.

If you clear the CMOS, the case open may be detected. Please adjust

the BIOS option “Clear Status” to clear the record of previous chassis

intrusion status.

2.6 Onboard Headers and Connectors

Onboard headers and connectors are NOT jumpers. Do NOT place

jumper caps over these headers and connectors. Placing jumper caps

over the headers and connectors will cause permanent damage of the

motherboard!

Serial ATA3 Connectors These four Serial ATA3
