How to verify my mainboard's name before bios update?

Solution 1:

Start a command prompt and execute the command:

wmic baseboard get product

This will list:

Product
B450 GAMING PRO CARBON AC (MS-7B85)

So you have a B450 GAMING PRO CARBON AC and not the MAX WIFI, so the the right file for you is the 7B85v1F4.zip.

If you want to start a BIOS update from a flash drive, make sure the ROM file is on the root of a FAT32-formatted USB stick and not within a subfolder.

MSI flash tool that is accessible from the board's BIOS does not allow browsing into subfolders. (At best it's the only file on the stick but it's not a requirement.)

I can also confirm that the latest BIOS provides better RAM stability for me as I am able with this BIOS to run my four 4 x 8192MB G.Skill RipJaws V DDR4-3200 DIMM CL16-18-18-38 at their official ratings, whereas the older BIOS only allowed settings in the 2666 at maximum.

Your mileage may vary, as unstable memory configuration may have different causes.

Solution 2:

Whatever Windows thinks is the motherboard is a good indication, but not an absolutely sure one.

For example, on my computer the motherboard exact version is not clearly indicated.

The only sure way is to open the computer case and look for the label written on the motherboard.

Solution 3:

Windows System Information panel will show you the computer baseboard manufacturer and product.
