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
