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.

2.1 Installing the CPU

1. Before you insert the 1151-Pin CPU into the socke t, please check if the PnP cap is on the socket, if the CPU sur face is unclean, or if th ere are any bent pins in the socket. Do not force to insert the CPU into the socket if above situ ation is found. Other wise, the CPU wil l be seriously d amaged.

2. Unplug all power cables be fore 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 always need to install identical (the same

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

2. It is unable to activate Dual Channel Memor y Te chnology 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.

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.

PCIE5 (PCIe 3.0 x1 slot) is used for PCI Express x1 lane width 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”. e illustration shows a 3-pin jumper whose pin1 and pin2 are “Short”

when a jumper cap is placed on these 2 pins.

Clear CMOS Jumper

(CLRMO S1)

(see p.7, No. 24)

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 pin2 and pin3 on CLRMOS1 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.

2.7 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 g raphics card driver 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 least th e 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.

2.7.1 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.

Z390 Pro4

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

with the graphics card you purchase, not

bundled with this motherboard. Please

refer to your graphics card vendor for

deta ils .)

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.

Increasing the CPU Ratio will increase the internal CPU clock speed without

aecting the clock speed of other components.

CPU Cache Ratio

e CPU Interna l Bus Speed Ratio. e maximum should be the same as the CPU

Ratio.

Minimum CPU Cache Ratio

Set the minimum CPU Internal Bus Speed Ratio.

BCLK Frequency

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

Increasing the BCLK will increase the internal CPU clock speed but also aect the

clock speed of other components.

Boot Performance Mode

Default is Max Non-Turbo performance mode. It will keep cpu Flex-ratio till OS

hando. Max Battery mode will set CPU ratio as x8 till OS hando. is option is
