Overview of Components

CPU Socket

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.
• Whenever the CPU is not installed, always protect the CPU socket pins by covering the socket with a plastic cap.
• If you purchased a separate CPU and heatsink/ cooler, Please refer to the documentation in the heatsink/ cooler package for more details about installation.
• This motherboard is designed to support overclocking. Before attempting to overclock, please make sure that all other system components can tolerate overclocking. Any attempt to operate beyond product specifications is not recommended. MSI® does not guarantee the damages or risks caused by inadequate operation beyond product specifications.

DIMM Slots

Memory module installation recommendation

Important

• Always insert memory modules in the DIMMA2 slot first.

• To ensure system stability for Dual channel mode, memory modules must be of the same type, number, and density.

• Some memory modules may operate at a lower frequency than the marked value when overclocking due to the memory frequency operating dependent on its Serial Presence Detect (SPD). Go to BIOS and find the DRAM Frequency to set the memory frequency if you want to operate the memory at the market or a higher frequency.

• It is recommended to use a more efficient memory cooling system for full DIMMs
  installation or overclocking.

• The stability and compatibility of the installed memory module depend on the installed CPU and devices when overclocking.

• Please refer to www.msi.com for more information on compatible memory.

PCI_E1~4:PCIe Expansion Slots

Important

• If you install a large and heavy graphics card, you need to use a tool such as MSI Graphics Card Bolster to support its weight to prevent deformation of the slot.
• For a single PCIe x16 expansion card installation with optimum performance, using the PCI_E1 slot is recommended.
• 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.

M2_1~4: M.2 Slots (Key M)

Important

• Intel® RST only supports PCIe M.2 SSD with UEFI ROM.
• If your M.2 SSD equips its own heatsink, please remove the M.2 rubber cube in the M.2 slot before installing M.2 SSD. Do not re-install the heatsink supplied with your motherboard.

UEFI BIOS
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.

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

UEFI advantages

• 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 an 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.

Incompatible UEFI cases

• 32-bit Windows operating system – this motherboard supports only Windows 10/ Windows 11 64-bit operating system.
• Older graphics card – the system will detect your graphics card. If you use older graphics cards, it may display a warning message There is no GOP (Graphics Output protocol) support detected in this graphics card.

Important: We recommend that you replace it with a graphics card supporting GOP/UEFI or use a CPU with integrated graphics for normal function.

2. Press the Delete key, when the Press DEL key to enter the Setup Menu, F11 to enter the Boot Menu message appears on the screen during the boot process.
