Frequently Asked Questions - B840M GAMING PLUS WIFI6E MSI

How to update the BIOS on the MSI B840M GAMING PLUS WIFI6E?
Use M-Flash in BIOS or MSI Center. Download the latest BIOS from MSI website, save to a USB drive, enter BIOS, and use M-Flash to select file. Ensure the system has stable power.
What RAM speeds are supported?
The board supports DDR5 memory with speeds up to 8000 MT/s (OC). Use XMP/EXPO profiles in BIOS to enable higher frequencies.
How do I connect Wi-Fi antennas?
Screw the included external antennas into the gold connectors on the rear I/O panel. Position them for optimal signal. If signal is poor, try rerouting antennas away from metal obstacles.
Can I use PCIe 5.0 graphics cards?
Yes, the PCIe 4.0 x16 slot is backward compatible with PCIe 5.0 cards. You may experience a negligible performance difference, as most GPUs are not bandwidth-limited.
How many M.2 SSDs can I install?
This motherboard has two M.2 slots. Both support PCIe 4.0 x4 and can also accommodate SATA M.2 drives in the lower slot.
Why is my Ethernet not working?
Install the latest Realtek LAN driver. Check if the network cable is securely connected and the router is active. In BIOS, ensure LAN is enabled. If using Windows, run the network troubleshooter.
Does the motherboard support RGB lighting?
Yes, it features Mystic Light RGB with onboard LEDs and 2 RGB headers (12V RGB and 5V ARGB) for compatible strips and fans. Control via MSI Center.
How to clear CMOS?
Power off the PC, disconnect the power cord, and remove the CMOS battery for about 30 seconds. Alternatively, use the JBAT1 jumper on board (check manual). This resets BIOS settings.
What is the warranty period?
MSI generally offers a 3-year limited warranty in most regions. Keep the invoice and register your product on MSI website for full coverage.
Can I use this board with Ryzen 9000 series?
Yes, with a compatible BIOS update. The AM5 socket supports all Ryzen 7000, 8000G, and 9000 series processors. Update BIOS to ensure smooth operation.

Revision History 69

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.

MSI B840M GAMING PLUS WIFI6E - UEFI BIOS - 1

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 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 1164-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.

MSI B840M GAMING PLUS WIFI6E - Incompatible UEFI cases - 1

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 find the BIOS version?

After entering the BIOS, find the BIOS version in the information box.

Ensure the computer is powered off before clearing the CMOS data. For more details, refer to the Clear CMOS jumper/button section in the manual.

Updating BIOS

Updating BIOS with M-FLASH

Before starting the M-Flash process, make sure you have:

- A USB flash drive with a capacity of 32GB or less that is formatted to FAT32.

MSI B840M GAMING PLUS WIFI6E - Updating BIOS with M-FLASH - 1

M-Flash only supports FAT32 format, and the USB flash drive should not exceed 32GB.

- A computer with internet access.

Please follow the steps below to update BIOS:

  1. Download the latest BIOS file from the MSI website that matches your motherboard model, and save it to the USB flash drive.
  2. If your motherboard has a Multi-BIOS switch, switch to the target BIOS ROM.
  3. Insert the USB flash drive into your motherboard's USB port.
  4. Enter flash mode by either:

  5. Rebooting and pressing Ctrl + F5 during POST, then clicking Yes to reboot the system.

  6. Rebooting and pressing Del during POST to enter BIOS, then clicking the M-FLASH button and clicking Yes to reboot.

  7. Select a BIOS file from the M-FLASH File menu and press Enter.

  8. When prompted by a File Check message, click Yes to start the BIOS update.

Once the update reaches 100%, the system will reboot automatically.

Updating the BIOS with MSI Center

Before updating:

  • Ensure the LAN driver is installed, and the internet connection is working properly.
  • Close all other applications before updating the BIOS.

To update BIOS:

  1. Install and launch MSI Center, then go to Support page.
  2. Select Live Update and click on Advance button.
  3. Select the BIOS file and click on Install button.
  4. The installation reminder will appear, then click the Install button.

The system will automatically restart to update the BIOS. Once the flashing process is complete, the system will restart.

Updating BIOS with Flash BIOS Button

  1. Download the latest BIOS file from the MSI website that matches your motherboard model.
  2. Rename the BIOS file to MSI.ROM, and save it to the root directory of a USB flash device.
  3. Connect the power supply to CPU_PWR1 and ATX_PWR1. (You don't need to install the CPU and memory.)
  4. Plug the USB flash device with the MSI.ROM file into the Flash BIOS Port on the rear I/O panel.
  5. Press the Flash BIOS Button to start flashing the BIOS. The LED will start flashing to indicate the process has begun.

The LED will turn off when the process is complete.
