Overview of Components

CPU Socket

Please install the CPU into the CPU socket as shown below.

• 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 the 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.

DIMM Slots

Please install the memory module into the DIMM slot as shown below.

Memory module installation recommendation

• 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 operates 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 marked or at 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 installed memory module depend on installed CPU and devices when overclocking.
• Please refer to www.msi.com for more information on compatible memory.

PCI_E1~3: PCIe Expansion Slots

PCI_E1: PCIe 4.0 x16 (From CPU)
PCI_E2: PCIe 3.0 x1 (From B660 chipset)
PCI_E3: PCIe 3.0 x4 (From B660 chipset)

• 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.

JFP1, JFP2: Front Panel Connectors

The JFP1 connector controls the power on, power reset, and the LEDs on your PC case/chassis. Power Switch/ Reset Switch headers allow you to connect power button/ reset button. Power LED header connects to LED light on the PC case, and HDD LED header indicates the activity of the hard disk. The JFP2 connector is for Buzzer and Speaker. To connect the cables from PC case to the right pins, please refer to the following images below.

Please note that Power LED and HDD LED have positive and negative connection, you need to link up the cable to the corresponding positive and negative port on the motherboard. Otherwise, LEDs won't work properly.

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 capabilities.

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 selftest process. It can also eliminate 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 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.

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

How to check the BIOS mode?

1. Power on your computer.
2. 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.
3. After entering the BIOS, you can check the BIOS Mode at the top of the screen.
   

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.

• BIOS items are regularly updated for better system performance. The items may be slightly different from the latest BIOS; therefore, the description is for reference only. You could also refer to the HELP information panel for BIOS item description.
