Chapter 2 Installation

is is a Micro 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.

•

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

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 th e power cord before changing a CPU or heatsink.

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.

1. For dual channel cong uration , you always need to in stall identical (the same

brand, speed , size and chip-type) DDR4 DIMM pairs.

2. It is unable to activate Du al 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.

Before installing an ex pansion card, please make sure that the power supply is
switched o or the power cord is unplugged. Plea se read the documentation of the
expan sion card and mak e necessary h ardware settings for the card before you start
the installation.

PCIe slots:

PCIE1 (PCIe 3.0 x1 slot) is used for PCI Express x1 lane width cards.

PCIE2 (PCIe 3.0 x16 slot) is used for PCI Express x16 lane width graphics cards.

For a better ther mal environme nt, ple ase connect a ch assis fan to the motherboard’s
chassis fan connector (CHA_ FAN1 or CHA_ FA N2 ) 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”.

A520M-HDV
A520M-HVS

Clear CMOS Jumper

(CLRMO S1)

(see p.6 or 7, No. 14)

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. Aer waiting for 15 seconds, use a jumper cap to

short the pins on CLR MOS1 for 5 seconds. However, please do not clear the

CMOS right aer 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 prole will be cleared only if the CMOS battery is

removed. Please remember toremove the jumper cap aer clearing the CMOS.

If you clear the CMOS, the case open may be detected. Pl ease adjust the BIOS option
“Clear Status” to clear the record of previou s chassis int rusion status.

SoC/Uncore OC Voltage(VID)

Specify the SoC/Uncore voltage (VDD_SOC) in mV to support memory and Innity 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 Innity

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

specications.

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.

Innity Fabric Frequency and Dividers

AMD Overclocking Setup Set Innity 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

suciently high MCLK can negate or overcome this penalty.
