SafetyInformation
∙∙ 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.

Important
∙∙ 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.
∙∙ Confirm that the CPU heatsink has formed a tight seal with the CPU before booting your system.
∙∙ 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 documentation in the heatsink/ cooler package for more details about installation.

Important |
|
|
Due to chipset resource usage, the available capacity of memory will be a little less |
||
than the amount of installed. |
|
|
∙∙ 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 |
||
memory on the motherboard. |

PCI_E1~2:PCIeExpansionSlots
PCI_E1: PCIe 3.0 x1 (PCH)
PCI_E2: PCIe 4.0/ 3.0 x16 (CPU)
Important
∙∙ If you install a large and heavy graphics card, you need to use a tool such as MSI Gaming Series Graphics Card Bolster to support its weight to prevent deformation of the slot.
∙∙ When adding or removing expansion cards, always turn off the power supply and unplug the power supply power cable from the power outlet. Read the expansion card’s documentation to check for any necessary additional hardware or software changes.

Important
∙∙ Please do not fold the SATA cable at a 90-degree angle. Data loss may result during transmission otherwise.
∙∙ SATA cables have identical plugs on either sides of the cable. However, it is recommended that the flat connector be connected to the motherboard for space saving purposes.

CPU_FAN1,SYS_FAN1:FanConnectors
PWM Mode fan connectors provide constant 12V output and adjust fan speed with speed control signal. When you plug a 3-pin (Non-PWM) fan to a fan connector in PWM mode, the fan speed will always maintain at 100%, which might create a lot of noise.

16 Overview of Components
UEFIBIOS
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.
Important
The term BIOS in this user guide refers to UEFI BIOS unless otherwise noted.
UEFIadvantages
∙∙ Fast booting - UEFI can directly boot the operating system and save the BIOS selftest 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.
IncompatibleUEFIcases
∙∙32-bit Windows operating system - this motherboard supports only 64-bit Windows 10 operating system.
∙∙Older graphics card - the system will detect your graphics card. When display a warning message There is no GOP (Graphics Output protocol) support detected in this graphics card.
Important
We recommend that you to use a GOP/ UEFI compatible graphics card.

BIOSSetup
The default settings offer the optimal performance for system stability in normal conditions. You should always keep the default settings to avoid possible system damage or failure booting unless you are familiar with BIOS.
Important
∙∙ BIOS items are continuous update for better system performance. Therefore, the description may be slightly different from the latest BIOS and should be held for reference only. You could also refer to the HELP information panel for BIOS item description.
∙∙ The BIOS items will vary with the processor.
EnteringBIOSSetup
Press Delete key, when the Press DEL key to enter Setup Menu, F11 to enter Boot Menu message appears on the screen during the boot process.

* When you press F10, a confirmation window appears and it provides the modification information. Select between Yes or No to confirm your choice.
ResettingBIOS
You might need to restore the default BIOS setting to solve certain problems. There are several ways to reset BIOS:
∙∙ Go to BIOS and press F6 to load optimized defaults. ∙∙ Short the Clear CMOS jumper on the motherboard.
Important
Please refer to the Clear CMOS jumper section for resetting BIOS.
