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

•

components. Failure to do so may cause physical injuries 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.

English

2.1 Installing the CPU

1. Before you insert the 1200-Pin CPU into the socke t, please check if the PnP cap is on the socket, if the CPU surface is unclean, or if there are any bent pins in the socket. Do not force to in sert the CPU into the socket if above situation is found. Otherwise, the CPU will be seriously damaged.

2. Unplug all power cables before installing the CPU.

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 a lways need to install identical (the same

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

2. It is unable to activate Dual Channel Me mory Technology w ith only one or three

memory module installed.

3. It is not allowed to ins tall 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 5 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 hardware 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.

PCIE3 (PCIe 3.0 x1 slot) is used for PCI Express x1 lane width cards.

PCIE4 (PCIe 3.0 x16 slot) is used for PCI Express x4 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

(CLRMO S1)

(see p.7, No. 30)

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.

2.8 CrossFireXTM and Quad CrossFireXTM Operation Guide

is motherboard supports 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 AM D certied.

2. Make sure that your graphics card drive r supports AMD CrossFireXTM technology. Download the drivers from the A MD’s website: www.amd.com

3. Make sure that your power supply unit (PSU) can provide at lea st the minimum power your syste m require s. It is recommended to use a AMD certied PSU. Plea se refer to the AMD’s website for d etail s.

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 de tailed installation guide.

2.8.1 Installing Two CrossFireXTM-Ready Graphics Cards

Step 1

Insert one graphics card into PCIE2 slot

and the other graphics card to PCIE4 slot.

Make sure that the cards are properly

seated on the slots.

English

CrossFire Bridge

Step 2

Connect two graphics cards by installing

system. You may run the UEFI SETUP UTILITY by pressing <F2> or <Del> right

aer you power on the computer, other wise, the Power-On-Self-Test (POST) will

continue with its test routines. If you wish to enter the UEFI SETUP UTILITY aer

POST, restart the system by pressing <Ctl> + <Alt> + <Delete>, or by pressing the

reset button on the system chassis. You may also restart by turning the system o

and then back on.

CPU Conguration

Multi Core Enhancement

Improve the system's performance by forcing the CPU to perform the highest

frequency on all CPU cores simultaneously. Disable to reduce power consumption.

CPU Ratio

e CPU speed is determined by the CPU Ratio multiplied with the BCLK.

aecting the clock speed of other components.

Ratio.

quency.

English

cies and voltage points for better power saving and heat dissipation.

Intel Thermal Velocity Boost Ratio Clipping

is service controls Core frequency reduction caused by high package tempera-

tures for processors that implement the Intel ermal Velocity Boost (TVB) feature.

the default max turbo frequency.

Intel Thermal Velocity Boost Voltage Optimizations

is service controls thermal based voltage optimizations for processors that

implment the Intel ermal Velocity Boost (TVB) feature.

Congure the current limit of the CPU core. A lower limit can protect the CPU and

save power, while a higher limit may improve performance.
