Chapter 2 Installation
This is a Micro ATX form factor motherboard. Before you install the motherboard,study the configuration of your chassis to ensure that the motherboard fits into it.

Pre-installation Precautions
Take note of the following precautions before you install motherboard components
or change any motherboard settings.

English• 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 orin the bag that comes with the components.
• When placing screws to secure the motherboard to the chassis, please do not overtighten the screws! Doing so may damage the motherboard.

92.1 Installing the CPU

Unplug all power cables before installing the CPU.

2.2 Installing the CPU Fan and Heatsink
After 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 off the power or remove the power cord before changing a CPU or heatsink.

This motherboard provides two 288-pin DDR4 (Double Data Rate 4) DIMM slots,
and supports Dual Channel Memory Technology.

1. For dual channel configuration, you always need to install identical (the samebrand, 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)
There are 2 PCI Express slots on the motherboard.
Before installing an expansion card, please make sure that the power supply isswitched 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.

PCIe slots:
PCIE1 (PCIe 3.0 x16 slot) is used for PCI Express x16 lane width graphics cards.
PCIE2 (PCIe 3.0 x1 slot) is used for PCI Express x1 lane width cards.

For a better thermal environment, please connect a chassis fan to the motherboard’s
chassis fan connector (CHA_FAN1/WP, CHA_FAN2/WP or CHA_FAN3/WP )when using multiple graphics cards.

2.5 Jumpers Setup
The 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(CLRCMOS1)(see p.6, No. 12)

2-pin Jumper

Short: Clear CMOS
Open: Default

CLRCMOS1 allows you to clear the data in CMOS. The 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, pleaseturn off the computer and unplug the power cord, then use a jumper cap to shortthe pins on CLRCMOS1 for 3 seconds. Please remember to remove the jumper
cap after clearing the CMOS. If you need to clear the CMOS when you just finish
updating the BIOS, you must boot up the system first, and then shut it down
before you do the clear-CMOS action.

EnglishIf 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.

232.6 Onboard Headers and Connectors
Onboard headers and connectors are NOT jumpers. Do NOT place jumper caps overthese headers and connectors. Placing jumper caps over the headers and connectors
will cause permanent damage to the motherboard.

PWRBTN (Power Button):
Connect to the power button on the chassis front panel. You may configure the way
to turn off your system using the power button.
RESET (Reset Button):
Connect to the reset button on the chassis front panel. Press the reset button torestart 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. The LED is on when
the system is operating. The LED keeps blinking when the system is in S1/S3 sleep
state. The LED is off when the system is in S4 sleep state or powered off (S5).
HDLED (Hard Drive Activity LED):
Connect to the hard drive activity LED on the chassis front panel. The LED is onwhen the hard drive is reading or writing data.
The front panel design may differ by chassis. A front panel module mainly consistsof power button, reset button, power LED, hard drive activity LED, speaker and etc.
When connecting your chassis front panel module to this header, make sure the wireassignments and the pin assignments are matched correctly.

Because the UEFI software 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.

SoC/Uncore OC Voltage(VID)
Specify the SoC/Uncore voltage (VDD_SOC) in mV to support memory and Infinity Fabricoverclocking. 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 isderived from your DRAM Voltage (VDDIO_Mem). As a result, VDDP voltage in mV canapproach but not exceed your DRAM Voltage.

English

CLD0 VDDG CCD Voltage Control

Timing.

Infinity Fabric Frequency and Dividers
AMD Overclocking Setup Set Infinity 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 sufficiently high
MCLK can negate or overcome this penalty.

DRAM Timing Configuration
