 The components included in this package are prone to damage from electrostatic

discharge (ESD). Please adhere to the following instructions to ensure successful

computer assembly.

 Ensure that all components are securely connected. Loose connections may cause

the computer to not recognize a component or fail to start.

 Hold the motherboard by the edges to avoid touching sensitive components.

 It is recommended to wear an electrostatic discharge (ESD) wrist strap when

handling the motherboard to prevent electrostatic damage. If an ESD wrist strap is

not available, discharge yourself of static electricity by touching another metal object

before handling the motherboard.

 Store the motherboard in an electrostatic shielding container or on an anti-static

pad whenever the motherboard is not installed.

 Before turning on the computer, ensure that there are no loose screws or metal

components on the motherboard or anywhere within the computer case.

 Do not boot the computer before installation is completed. This could cause

permanent damage to the components as well as injury to the user.

 If you need help during any installation step, please consult a certified computer

technician.

 Always turn off the power supply and unplug the power cord from the power outlet

before installing or removing any computer component.

 Keep this user guide for future reference.

 Keep this motherboard away from humidity.

 Make sure that your electrical outlet provides the same voltage as is indicated on

the PSU, before connecting the PSU to the electrical outlet.

 Place the power cord such a way that people can not step on it. Do not place

anything over the power cord.

 All cautions and warnings on the motherboard should be noted.

 If any of the following situations arises, get the motherboard checked by service

personnel:

 Liquid has penetrated into the computer.

 The motherboard has been exposed to moisture.

 The motherboard does not work well or you can not get it work according to

user guide.

 The motherboard has been dropped and damaged.

 The motherboard has obvious sign of breakage.

 Do not leave this motherboard in an environment above 60°C (140°F), it may

damage the motherboard.

Always unplug the power cord from the power outlet before installing or removing

the CPU.



Please retain the CPU protective cap after installing the processor. MSI will deal

with Return Merchandise Authorization (RMA) requests if only the motherboard

comes with the protective cap on the CPU socket.



When installing a CPU, always remember to install a CPU heatsink. A CPU heatsink

is necessary to prevent overheating and maintain system stability.



Overheating can seriously damage the CPU and motherboard. Always make sure

the cooling fans work properly to protect the CPU from overheating. Be sure to apply

an even layer of thermal paste (or thermal tape) between the CPU and the heatsink to

enhance heat dissipation.



If you purchased a separate CPU and heatsink/ cooler, Please refer to the docu-

mentation in the heatsink/ cooler package for more details about installation.

Due to chipset resource usage, the available capacity of memory will be a little less



Please note that the maximum capacity of addressable memory is 4GB or less

for 32-bit Windows OS due to the memory address limitation. Therefore, we recom

mended that you to install 64-bit Windows OS if you want to install more than 4GB

MSI UEFI BIOS is compatible with UEFI (Unified Extensible Firmware Interface)

architecture. UEFI has many new functions and advantages that traditional BIOS

cannot achieve, and it will completely replace BIOS in the future. The MSI UEFI

BIOS uses UEFI as the default boot mode to take full advantage of the new chipset’s

capabilities. However, it still has a CSM (Compatibility Support Module) mode to be

compatible with older devices. That allows you to replace legacy devices with UEFI

compatible devices during the transition.

The term BIOS in this user guide refers to UEFI BIOS unless otherwise noted.



 Fast booting - UEFI can directly boot the operating system and save the BIOS self-

test process. And also eliminates the time to switch to CSM mode during POST.

 Supports for hard drive partitions larger than 2 TB.

 Supports more than 4 primary partitions with a GUID Partition Table (GPT).

 Supports unlimited number of partitions.

 Supports full capabilities of new devices - new devices may not provide backward

compatibility.

 Supports secure startup - UEFI can check the validity of the operating system to

ensure that no malware tampers with the startup process.
