A520M-HDV
A520M-HVS
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.
Failure to do so may cause physical injuries to you 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.

2.2 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.

2.3 Installing Memory Modules (DIMM)
is motherboard provides two 288-pin DDR4 (Double Data Rate 4) DIMM slots,
and supports Dual Channel Memory Technology.
AMD non-XMP Memory Frequency Support
Ryzen Series CPUs (Matisse):
Ryzen Series APUs (Renoir):
1. For dual channel conguration, you always need to install identical (the same
brand, speed, size and chip-type) DDR4 DIMM pairs.
2. It is unable to activate Dual Channel Memory Technology with only one memory
module installed.
3. It is not allowed to install a DDR, DDR2 or DDR3 memory module into a DDR4
slot; otherwise, this motherboard and DIMM may be damaged.

2.4 Expansion Slots (PCI Express Slots)
ere are 2 PCI Express slots on the motherboard.
PCIe slots:
PCIE1 (PCIe 3.0 p29-x1 slot) is used for PCI Express p29-x1 lane width cards.
PCIE2 (PCIe 3.0 x16 slot) is used for PCI Express x16 lane width graphics cards.
Before installing an expansion card, please make sure that the power supply is
switched o 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.
For a better thermal environment, please connect a chassis fan to the motherboard’s
chassis fan connector (CHA_FAN1 or CHA_FAN2 ) when using multiple graphics cards.

2.5 Jumpers Setup
e illustration shows how jumpers are setup. When the jumper cap is placed on
the pins, the jumper is “Short”. If no jumper cap is placed on the pins, the jumper is
“Open”.
Clear CMOS Jumper
(CLRMOS1)
(see p.6 or 7, No. 14)
Short: Clear CMOS
Open: Default
CLRMOS1 allows you to clear the data in CMOS. To clear and reset the system
parameters to default setup, please turn o the computer and unplug the power
cord from the power supply. Aer waiting for 15 seconds, use a jumper cap to
short the pins on CLRMOS1 for 5 seconds. However, please do not clear the
CMOS right aer 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 action. Please be noted that the password,
date, time, and user default prole will be cleared only if the CMOS battery is
removed. Please remember toremove the jumper cap aer clearing the CMOS.
2-pin Jumper
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
System Panel Header
(9-pin PANEL1)
(see p.6 or 7, No. 8)
Connect the power
switch, reset switch and
system status indicator on
the chassis to this header
according to the pin
assignments below. Note
the positive and negative
pins before connecting
the cables.
PWRBTN (Power Switch):
Connect to the power switch on the chassis front panel. You may congure the way to
turn o your system using the power switch.
RESET (Reset Switch):
Connect to the reset switch on the chassis front panel. Press the reset switch to restart
the computer if the computer freezes and fails to perform a normal restart.
PLED (System Power LED):
Connect to the power status indicator on the chassis front panel. e LED is on when
the system is operating. e LED keeps blinking when the system is in S3 sleep state.
e LED is o when the system is in S4 sleep state or powered o (S5).
HDLED (Hard Drive Activity LED):
Connect to the hard drive activity LED on the chassis front panel. e LED is on when
the hard drive is reading or writing data.
e front panel design may dier by chassis. A front panel module mainly consists of
power switch, reset switch, power LED, hard drive activity LED, speaker and etc. When
connecting your chassis front panel module to this header, make sure the wire assign-
ments and the pin assignments are matched correctly.
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 to the motherboard.

2.7 M.2_SSD (NGFF) Module Installation Guide
The M.2, also known as the Next Generation Form Factor (NGFF), is a small size and
versatile card edge connector that aims to replace mPCIe and mSATA. The Ultra M.2
Socket supports M Key type 2242/2260/2280 M.2 SATA3 6.0 Gb/s module and M.2 PCI
Express module up to Gen3 p35-x4 (32 Gb/s).
Installing the M.2_SSD (NGFF) Module
Step 1
Prepare a M.2_SSD (NGFF) module
and the screw.
Step 2

4.3 OC Tweaker Screen
In the OC Tweaker screen, you can set up overclocking features.
SoC/Uncore OC Voltage(VID)
Specify the SoC/Uncore voltage (VDD_SOC) in mV to support memory and Innity Fabric
overclocking. VDD_SOC also determines the GPU voltage on processors with integrated
graphics. “SoC/Uncore OC Mode” needs to be enabled to force this voltage.
CLD0 VDDP Voltage Control
AMD Overclocking Setup VDDP is a voltage for the DDR4 bus signaling (PHY), and it is
derived from your DRAM Voltage (VDDIO_Mem). As a result, VDDP voltage in mV can
approach but not exceed your DRAM Voltage.
CLD0 VDDG CCD Voltage Control
AMD Overclocking Setup VDDG CCD represents voltage for the data portion of the Innity
Fabric. It is derived from the CPU SoC/Uncore Voltage (VDD_SOC). VDDG can approach
but not exceed VDD_SOC.
Because the UEFI soware is constantly being updated, the following UEFI setup
screens and descriptions are for reference purpose only, and they may not exactly
match what you see on your screen.

CLD0 VDDG IOD Voltage Control
AMD Overclocking Setup VDDG IOD represents voltage for the data portion of the Innity
Fabric. It is derived from the CPU SoC/Uncore Voltage (VDD_SOC). VDDG can approach
but not exceed VDD_SOC.
DRAM Information
Load XMP Setting
Load XMP settings to overclock the memory and perform beyond standard
specications.
DRAM Frequency
If [Auto] is selected, the motherboard will detect the memory module(s) inserted
and assign the appropriate frequency automatically. Setting DRAM Frequency can
adjust DRAM Timing.
Innity Fabric Frequency and Dividers
AMD Overclocking Setup Set Innity Fabric frequency (FCLK). Auto: FCLK =
MCLK. Manual: FCLK must be less than or equal to MCLK for best performance in
most cases. Latency penalties are incurred if FCLK and MCLK are mismatched, but
suciently high MCLK can negate or overcome this penalty.
DRAM Timing Conguration
External Voltage Settings and Load-line Calibration
+1.8V Voltage
Congure the voltage for the +1.8V Voltage. e default value is [Auto].
DRAM Voltage
Congure the voltage for the DRAM Voltage.
VDDP
Congure the voltage for the VDDP.
