So i wrote to MSI support for advice on how to modify DMI information but got this reply:

" We are really sorry, DMI information need to be restored by DMI Tool, but we did not provide the Tool to user, if you can find or download the DMI Tool from the Internet, you can fill these information in bios. If you cannot find the tool, please contact your reseller (The place you bought this MB from), then ask for some help. If the reseller for some reason cannot help, we have to ask you to contact MSI distributor or MSI Office near your place to seek further help. Sorry for any inconvenience caused."

So if msi cant provide it and tells me to look on the internet msi forum is the next logical step right? Could you please provide me that tool?

Hello 😊

🧰 [TUTORIAL] Fix Wrong Motherboard Model in Windows / MSI Center

(Real case: MSI B650 detected as a Z690)


🔸 THE PROBLEM :

In Windows (msinfo32) and MSI Center, my motherboard was incorrectly detected as:
PRO Z690-P DDR4 (MS-7D36)

while my real board is actually:
MSI PRO B650-S WIFI (MS-7E26)

🔸 STEP 1 — DOWNLOAD THE CORRECT TOOL

I used AMIDEWIN, included in the official AMI DMIEdit EFI/AMI package.

Download link:

If the link stops working, search for:
“AMI DMIEdit EFI AMIDEWINx64.exe”

This is an official tool from American Megatrends (AMI) used to edit SMBIOS data.

🔸 STEP 2 — PREPARE THE FOLDER

1. Extract the downloaded ZIP file.

2. Move the extracted folder to your C: drive and rename it to AMI

You should now have: C:\AMI\amidewinx64.exe

🔸 STEP 3 — OPEN COMMAND PROMPT AS ADMINISTRATOR

1. Press Start, type “cmd”.

2. Right-click → Run as administrator.

3. Go to the AMI folder:

cd C:\AMI

🔸 STEP 4 — CHECK CURRENT DMI INFORMATION

Run this command to list all DMI/SMBIOS data:

amidewinx64.exe /ALL

You should see something like:

(/SP)System product R Done “MS-7E26”

(/BP)Baseboard product R Done “PRO Z690-P DDR4 (MS-7D36)”

(/BS)Baseboard Serial number R Done “6HTSETAFMKD3SCE”

STEP 5 — FIX INCORRECT FIELDS

In my case, I had to correct the following:

System Product (/SP) from MS-7D36 → MS-7E26

Baseboard Product (/BP) from PRO Z690-P DDR4 (MS-7D36) → PRO B650-S WIFI (MS-7E26)

Baseboard Serial Number (/BS) from old serial → real serial (printed on motherboard box or near ATX power connector)

Commands used:

amidewinx64.exe /SP “MS-7E26”

amidewinx64.exe /BP “PRO B650-S WIFI (MS-7E26)”

amidewinx64.exe /BS “YOUR_SERIAL_NUMBER”

IMPORTANT:

Always use quotes “ “ if your text contains spaces or parentheses,

otherwise the command will fail with “Unknown command”.

🔸 STEP 6 — REBOOT AND VERIFY

After applying the changes, reboot your PC and check:

• msinfo32

• MSI Center

They should now show the correct board name:

PRO B650-S WIFI (MS-7E26)


✅ QUICK SUMMARY

1. Download DMIEdit EFI/AMI

2. Extract to C:\AMI

3. Open cmd as admin → cd C:\AMI

4. amidewinx64.exe /ALL (check current data)

5. Run:

amidewinx64.exe /SP “MS-7E26”

amidewinx64.exe /BP “PRO B650-S WIFI (MS-7E26)”

amidewinx64.exe /BS “YOUR_SERIAL_NUMBER”

6. Reboot and confirm
