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 the power cord before changing a CPU or heat sink.

2.3 Installing Memory Modules (DIMM)
is motherboard provides four 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 or three 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.
4. We suggest that you install the memory modules on DDR4 _A 2 and DDR4_ B2 rst for better DRAM compatibility on 2 DIMMs conguration.

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
“O pen”.
English
Clear CMOS Jumper
(CLRCMO S1)
(see p.7, No. 26)
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.

2.8 CrossFireXTM and Quad CrossFireXTM Operation Guide
is motherboard supports CrossFireXTM and Quad CrossFireXTM that allows you
to install up to two identical PCI Express x16 graphics cards.
1. You should only use identical CrossFireXTM-ready g raphics cards that are AM D certied.
2. Make sure that your graphics card driver support s AMD CrossFireXTM technology. Download the drivers f rom the AMD’s website: www.amd.com
3. Make sure that your power supply unit (PSU) can pro vide at l east the minimum power your syste m require s. It is recommended to use a AMD ce rtied PSU. Please refer to the AMD’s website for details.
4. If you pair a 12-pipe CrossFireXTM Edition card with a 16-pipe card, both cards will operate a s 12-pipe cards while in CrossFireXTM mode.
5. Dierent CrossFireXTM cards may require dierent method s to enable CrossFi­reXTM. Please refer to A MD graphics card manuals for detailed installation guide .
2.8.1 Installing Two CrossFireXTM-Ready Graphics Cards
Step 1
Insert one graphics card into PCIE1 slot
and the other graphics card to PCIE3 slot.
Make sure that the cards are properly
seated on the slots.

Overclock Mode(Bus Speed)
Select the overclock mode. Warning! When overclocking also the PCIe, PCI, SATA and
USB busses will be overcloked which may cause instability or failure. Please install an
operating system and the drivers required before overclocking, or else your HDD's may be
undetectable. Overclocking is not supported if the monitor is connected via the onboard
D-Bus/VGA connector.
CPU Frequency and Voltage(VID) Change
If this item is set to [Manual], the multiplier and voltage will be set based on user selection.
Final result is depending on the CPU's capability.

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.
CLD0 VDDG IOD Voltage Control
AMD Overclocking Setup VDDG IOD 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.

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.
