Overview of Components

CPU Socket

The AM5 socket is a modern CPU socket designed for AMD processors. It is a key component in contemporary computing systems, providing the foundation for powerful and efficient CPUs.

Installing the CPU to the AM5 socket

The surface of the AM5 CPU has two notches and a golden triangle to assist in correctly lining up the CPU for motherboard placement. The golden triangle is the Pin 1 indicator.

To install the CPU, align the two notches on the AM5 socket with the two corresponding notches on the CPU. Please ensure that the gold triangle on the CPU serves as the PIN 1 indicator during the installation process.

Distance from the center of the CPU socket to the nearest DIMM slot.

Important

• When changing the processor, the system configuration could be cleared and reset BIOS to default values, due to the AM5 processor's architecture.
• Please ensure that the motherboard and power supply are turned off and always disconnect 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.
• Whenever the CPU is not installed, always protect the CPU socket pins by covering the socket with the protective cap.
• The CPU should only fit in one orientation, so do not force it. Gently place the CPU into the socket without applying excessive pressure.
• Please handle the CPU by the edges only; avoid touching the pins or the surface of the CPU. Any damage to the pins can result in a malfunctioning CPU.
• When installing a CPU, always remember to install a CPU heatsink. A CPU heatsink is necessary to prevent overheating and maintain system stability.
• Please install the CPU cooler according to the manufacturer's instructions. Make sure it is securely a tight seal with the CPU and attached to the motherboard to ensure proper heat dissipation.
  • 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.
• 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.

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. 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 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 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 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.

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

BIOS Setup

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.

• It’s not recommended to update BIOS when system has no issue.
• BIOS items are continuously updated for better system performance. Therefore, the description may be slightly different from the latest BIOS and should be for reference only. You could also refer to the HELP information panel in BIOS.
• The BIOS screens, options and settings will vary depending on the products you have.
