Chapter 2 Installation
is is a Micro ATX form factor 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.
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.

Please save the cover if the pro cessor is removed. e cover must be placed if you wish
to return the mothe rboard for aer ser vice.
A620M-HDV/M.2
2.2 Installing the CPU Fan and Heatsink
Aer 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 two 288-pin DDR5 (Double Data Rate 5) DIMM slots,
and supports Dual Channel Memory Technology.
1. For dual channel conguration, 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 memory
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.5, No. 7)
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 aer 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.

is motherboard is equipped with AMD USB BIOS Flashback feature that al lows you to update
BIOS without powering on the system.
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.
USB Drive Requirements
e USB drive that is used for the BIOS update feature should meet the following requirements:
• USB 2.0 only
• Capacit y up to 32GB
• Must be formatted as FAT16 or FAT32.
Root Directory Files
In the root directory there are two required les:
• BIOSUBU.BIN (required)
• PSPBIOS.IMG (required)
To use the USB BIOS Flashback f unction, please follow the steps below.
1. Download the latest BIOS le and BIOSUBU.BIN le from ASRock's website:
http://www.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 format ted as FAT16 or FAT32.
3. Extract BIOS le from the zip le.
4. Rename the le to “PSPBIOS.IMG”. Save it and BIOSUBU.BIN le to the root directory of X:
USB ash drive.
5. Insta ll the CPU, CPU fan and DRAM on t he motherboard. It is recommended to install the
CPU fan to CPU_ FA N1 connector. Plug the 8-pin ATX 12V power connector and 24-pin ATX
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 system sta rts BIOS
ashi ng automatically and the L ED starts to blink.
8. Wait unti l the LED stops bli nki ng, ind icating that BIOS ashing has been completed. is
