Chapter 2 Installation

is is an 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 be fore changing a CPU or heatsink .

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guration, you always need to install identical (the same

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

2. It is unable to activate Dual Channel Memory Technology w ith only one or three
memory module installed.

3. It is not allowed to instal l a DDR, DDR2 or DDR 3 memory modul e into a DDR4
slot; otherwise, thi s motherboard and DIMM may be damaged.

4. We sugge st that you install the memory modules on DDR4_ A2 and DDR4_B2 rst
for better DRA M compatibility on 2 DIMMs conguration.

2.4 Expansion Slots (PCI Express Slots)

ere are 5 PCI Express slots on the motherboard.

Before installing an expansion c ard, please mak e sure that the powe r supply is switched o
or the power cord is unplugged. Please read the documentation of the expansion c ard and
make necessary hardware settings for the card before you start the installation.

PCIe slots:

PCIE1 (PCIe 4.0 x16 slot) is used for PCI Express x16 lane width 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

“O pen”.

Clear CMOS Jumper

(CLR CMOS1)

(see p.8, No. 23)

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.

e Clear CMOS Button has the same func tion as the Clear CMOS jumpe r.

2.9 CrossFireXTM , 3-Way CrossFireXTM and Quad CrossFireXTM
Operation Guide

is motherboard supports CrossFireXTM, 3-way CrossFireXTM and Quad

CrossFireXTM that allows you to install up to three identical PCI Express x16

graphics cards.

1. You should only use identical CrossFireXTM-ready g raphics cards that are AMD
certied.

2. Make sure that your graphics card driver supports AMD CrossFireXTM technology.
Download the dr ivers from the AMD’s website: www.amd.com

3. Make sure that your power supply unit (PSU) can provide at least the minimum
power your system requires. It is recommended to use a AM D certied PSU. Plea se
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 methods to enable CrossFi­reXTM. Please refer to A MD graphics card manuals for detailed installation guide.

2.9.1 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.

English

CrossFire Bridge

Step 2

Connect two graphics cards by installing

a CrossFire Bridge on the CrossFire Bridge

Interconnects on the top of the graphics

cards. (e CrossFire Bridge is provided

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.

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.
