Chapter 2: Installation
Before you install the motherboard, study the conguration of your chassis to ensure
that the motherboard ts into it.
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.
2.1 Screw Holes
Place screws into the holes to secure the motherboard to the chassis.
Do not over-tighten the screws! Doing so may damage the motherboard.
2.2 Pre-installation Precautions
Take note of the following precautions before you install motherboard components
or change any motherboard settings.
1. Unplug the power cord from the wall socket before touching any component.
2. To avoid damaging the motherboard components due to static electricity,
NEVER place your motherboard directly on the carpet or the like. Also
remember to use a grounded wrist strap or touch a safety grounded object
before you handle components.
3. Hold components by the edges and do not touch the ICs.
4. Whenever you uninstall any component, place it on a grounded antistatic pad or
in the bag that comes with the component.
Before you install or remove any component, ensure that the power is
switched o󰀨 or the power cord is detached from the power supply.
Failure to do so may cause severe damage to the motherboard, peripherals,
and/or components.

12
2.3 Installation of Memory Modules (SO-DIMM)
This motherboard provides two 262-pin DDR5 (Double Data Rate 5) SO-DIMM
slots.
Step 1. Align a SO-DIMM on the slot such that the notch on the SO-DIMM
matches the break on the slot.
1. The SO-DIMM only ts in one correct orientation. It will cause permanent damage
to the motherboard and the SO-DIMM if you force the SO-DIMM into the slot at
incorrect orientation.
2. Please do not intermix di󰀨erent voltage SO-DIMMs on this motherboard.
Step 2. Firmly insert the SO-DIMM into the slot until the retaining clips at both
ends fully snap back in place and the SO-DIMM is properly seated.

13
2.4 Expansion Slots (M.2 Slots)
There are 2 M.2 slots on this motherboard.
M.2 for SSD: 1 x M.2 (KEY M, 2242/2260/2280) with PCIe Gen4 x 4
* M.2 Key M 2280(Supported by bracket)
M.2 for Wi-Fi: 1 x M.2 (Key E, 2230) with PCIe x1, USB 2.0 for Wireless.
M.2 Key-M Socket (M2M_1) M.2 Key-E Socket (M2E_1)
* Pin6 and Pin8 are dened as USB 2.0
signal to support Key-M to Key-B exten-
sion card.

Chapter 3: UEFI SETUP UTILITY
3.1 Introduction
This section explains how to use the UEFI SETUP UTILITY to congure your
system. The UEFI chip on the motherboard stores the UEFI SETUP UTILITY. You
may run the UEFI SETUP UTILITY when you start up the computer. Please press
<F2> or <Del> during the Power-On-Self-Test (POST) to enter the UEFI SETUP
UTILITY, otherwise, POST will continue with its test routines.
If you wish to enter the UEFI SETUP UTILITY after 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.
Because the UEFI software is constantly being updated, the
following UEFI setup screens and descriptions are for reference
purpose only, and they may not exactly match what you see on
your screen.
3.1.1 UEFI Menu Bar
The top of the screen has a menu bar with the following selections:
Main To set up the system time/date information
Advanced To set up the advanced UEFI features
H/W Monitor To display current hardware status
Security To set up the security features
Boot To set up the default system device to locate and load the
Operating System
Exit To exit the current screen or the UEFI SETUP UTILITY
Use < > key or < > key to choose among the selections on the menu
bar, and then press <Enter> to get into the sub screen. You can also use the
mouse to click your required item.

18
3.1.2 Navigation Keys
Please check the following table for the function description of each navigation
key.
Navigation Key(s) Function Description
/ Moves cursor left or right to select Screens
/ Moves cursor up or down to select items
+ / - To change option for the selected items
<Enter> To bring up the selected screen
<F1> To display the General Help Screen
<F7> Discard changes
<F9> To load optimal default values for all the settings
<F10> To save changes and exit the UEFI SETUP UTILITY
<F12> Print screen
<ESC> To jump to the Exit Screen or exit the current screen
3.2 Main Screen
When you enter the UEFI SETUP UTILITY, the Main screen will appear and display
the system overview.

19
Setting wrong values in this section may cause
the system to malfunction.
3.3 Advanced Screen
In this section, you may set the congurations for the following items: CPU Congu-
ration, Chipset Conguration, Storage Conguration, Super IO Conguration, ACPI
Conguration, USB Conguration, and Trusted Computing.
DASH Support
Enable or disable Realtek Lan DASH Function.
Instant Flash
Instant Flash is a UEFI ash utility embedded in Flash ROM. This conve-
nient UEFI update tool allows you to update system UEFI without entering
operating systems rst like MS-DOS or Windows®. Just launch this tool
and save the new UEFI le to your USB ash drive, oppy disk or hard
drive, then you can update your UEFI only in a few clicks without prepar-
ing an additional oppy diskette or other complicated ash utility. Please
be noted that the USB ash drive or hard drive must use FAT32/16/12 le
system. If you execute Instant Flash utility, the utility will show the UEFI
les and their respective information. Select the proper UEFI le to update
your UEFI, and reboot your system after UEFI update process completes.

20
3.3.1 CPU Conguration
PSS Support
Enable/disable the generation of ACPI _PPC, _PSS, and _PCT objects.
Core Performance Boost
Core Performance Boost controls whether the processor transitions to a
higher frequency than the processor's rated speed if the processor has
available power and is within temperature specications. The default value
is [Enabled].
Global C-state Control
Enable/Disable Global C-state Control.
SVM Mode
When this is set to [Enabled], a VMM (Virtual Machine Architecture) can
utilize the additional hardware capabilities provided by AMD-V. The default
value is [Enabled]. Conguration options: [Enabled] and [Disabled].
CPU Operation Mode
If working at [Normal Mode], M/B works with the default Smart Fan Setting
and can provide better cooler experience. If [Performance Mode] is se-
lected, CPU can provide optimal performance, but the CPU fan speed will
work at higher speed.
