Chapter 2 Installation

is 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.

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

•

components. Failure to do so may cause physical injuries and damages to motherboard

components.

In order to avoid damage from static electricity to the motherboard’s components,

•

NEVER place your motherboard directly on a carpet. Also remember to use a

grounded wrist strap or touch a safety grounded object before you handle the

components.

Hold components by the edges and do not touch the ICs.

•

Whenever you uninstall any components, place them on a grounded anti-static pad or

•

in the bag that comes with the components.

When placing screws to secure the motherboard to the chassis, please do not over-

•

tighten the screws! Doing so may damage the motherboard.

2.1 Installing the CPU

1. Before you inser t the 1718-Pin CPU into the sock et, please check if the P nP cap
is on the socket, 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.
Other wise, the CPU wil l be seriously damaged.

2. Unplug all power cables before installing the CPU.

Make sure the black cover plate

is always in place until it pops o

Please save the cover if the pro cessor is removed. e cover must be placed if you wish
to return the mothe rboard for aer ser vice.

2.2 Installing the CPU Fan and Heatsink

Aer 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 dissipation. Make sure that the

CPU and the heatsink are securely fastened and in good contact with each other.

Please turn o the power or remove the power cord before chang ing a CPU or heatsink .

2.3 Installing Memory Modules (DIMM)

is motherboard provides four 288-pin DDR5 (Double Data Rate 5) DIMM slots,

and supports Dual Channel Memory Technology.

1. For dual channel conguration, you always need to install identical (the same

brand, speed, size and chip-type) DDR5 DIMM pairs.

2. It is unable to activate Dual C hannel Memory Technology with only one or three
memor y module installed.

3. It is not allowed to in stall a DDR, DDR2 , DDR3 or DDR4 memory module into a
DDR5 slot; otherwise, this motherboard an d DIMM may be damaged.

4. e DIMM only ts in one correct orientation. It w ill cause per manent d amage to
the mothe rboard and the DIMM if you force the DIMM into the slot at incorrect
orientation.

the pins, the jumper is “Short”. If no jumper cap is placed on the pins, the jumper is

“Open”.

Clear CMOS Jumper

(CLRCMOS1) (see p.6, No. 20)

CLRCMOS1 allows you to clear the data in CMOS. e data in CMOS includes

system setup information such as system password, date, time, and system setup

parameters. To clear and reset the system parameters to default setup, please

turn o the computer and unplug the power cord, then use a jumper cap to short

the pins on CLRCMOS1 for 3 seconds. Please remember to remove the jumper

cap aer clearing the CMOS. 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 action.

USB BIOS Flashback port

ASRock BIOS Flashback feature allows you to update BIOS without powering on t he system,
even wit hout CPU.

Before u sing the BIOS Flashback function, plea se suspend BitLocker and any encryp­tion or security relying on the TPM. Make sure that you have already stored and
backup -ed the recovery key. If the recover y key is missing while encryption is ac tive,
the data w ill stay encrypted and the syste m will not boot into the operating system . It
is recommended to disable fTPM before updating the BIOS. Otherwise an unpredict­able failure may occ ur.

To use the USB BIOS Flashback f unction, Please follow the steps below.

1. Download the latest BIOS le from ASRock 's website : http://ww w.asrock.com.

2. Copy t he BIOS le to your USB ash d rive. Please make sure the le system of

your USB ash drive must be FAT32.

3. Extract BIOS  le from the zip le.

4. Rename the le to “creative.rom” and save it to t he root director y of X: USB ash drive.

5. Plug the 24 pin power connector to the motherboard. en turn on the power supply's AC
switch.
*ere is no need to power on the system.

6. en plug you r USB drive to the USB BIOS Flashback port.

7. Press the BIOS Flashback Switch for about three seconds. en the LED star ts to blink.

8. Wait unti l the LED stops bli nki ng, ind icating that BIOS ashing has been completed.
*If the LED light turns solid green, this means that the BIOS Flashback is not
operating properly. Please make sure that you plug the USB drive to the USB BIOS Flashback
port.
**If the LED does not light up at all then please disconnect power from the system and
remove/disconnect the CMOS bat tery from the mot herboard for several minutes. Reconnect
power and battery and try again.
