Z390 Pro4

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.

Chapter 2 Installation

English

2.1 Installing the CPU

1. Before you insert the 1151-Pin CPU into the socket, 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 insert 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.

English

Please save and replace the cover if the processor is removed. e cover must be

placed if you wish to return the motherboard for aer service.

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.

Dual Channel Memory Conguration

e DIMM only ts in one correct orientation. It will cause permanent damage to

the motherboard and the DIMM if you force the DIMM into the slot at incorrect

orientation.

Priority DDR4_A1 DDR4_A2 DDR4_B1 DDR4_B2

1 Populated Populated

2 Populated Populated Populated Populated

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 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.

English

Z390 Pro4

English

2.4 Expansion Slots (PCI Express Slots)

ere are 5 PCI Express slots on the motherboard.

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.

PCIe Slot Congurations

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.

Before installing an expansion card, please make sure that the power supply is

switched o 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.

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

(CLRMOS1)

(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.

restart 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. e LED is on when

the system is operating. e LED keeps blinking when the system is in S1/S3 sleep

state. e LED is o when the system is in S4 sleep state or powered o (S5).

HDLED (Hard Drive Activity LED):

Connect to the hard drive activity LED on the chassis front panel. e LED is on

when the hard drive is reading or writing data.

e front panel design may dier by chassis. A front panel module mainly consists

of 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 wire

assignments and the pin assignments are matched correctly.

Onboard headers and connectors are NOT jumpers. Do NOT place jumper caps over

these headers and connectors. Placing jumper caps over the headers and connectors

will cause permanent damage to the motherboard.

2.7 CrossFireX

and Quad CrossFireX

Operation Guide

is motherboard supports CrossFireX

and Quad CrossFireX

that allows you

to install up to three identical PCI Express x16 graphics cards.

2.7.1 Installing Two CrossFireX

-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.

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

details.)

1. You should only use identical CrossFireX

-ready graphics cards that are AMD

certied.

2. Make sure that your graphics card driver supports AMD CrossFireX

technology.

Download the drivers 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 AMD certied PSU. Please

refer to the AMD’s website for details.

4. If you pair a 12-pipe CrossFireX

Edition card with a 16-pipe card, both cards will

operate as 12-pipe cards while in CrossFireX

mode.

5. Dierent CrossFireX

cards may require dierent methods to enable CrossFi-

reX

. Please refer to AMD graphics card manuals for detailed installation guide.

CrossFire Bridge

English

Step 3

Connect a VGA cable or a DVI cable to the

monitor connector or the DVI connec-

tor of the graphics card that is inserted to

PCIE2 slot.

English

Z390 Pro4

Step 1

Power on your computer and boot into OS.

Step 2

Remove the AMD drivers if you have any VGA drivers installed in your system.

Step 3

Install the required drivers and CATALYST Control Center then restart your

computer. Please check AMD’s website for details.

2.7.2 Driver Installation and Setup

Step 4

Double-click the AMD Catalyst Control

Center icon in the Windows

system tray.

Step 5

In the le pane, click Performance and

then AMD CrossFireX

. en select

Enable AMD CrossFireX and click Apply.

Select the GPU number according to your

graphics card and click Apply.

AMD Catalyst Control Center

e Catalyst Uninstaller is an optional download. We recommend using this utility

to uninstall any previously installed Catalyst drivers prior to installation. Please

check AMD’s website for AMD driver updates.

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 Internal Bus Speed Ratio. e maximum should be the same as the CPU

Ratio.

Minimum CPU Cache Ratio
