Hello friends!

I'm having a problem with identifying my motherboard, I have a ROG STRIX B550-F GAMING WIFI II and the name simply doesn't appear correctly in the settings, only numbers appear, below I'll put a screenshot of the CPU-Z.

Does anybody know how to solve this?

Hello! @Jiaszzz_ROG 

I bought this used motherboard on ebay, and it had about 4 bios versions out of date, but when I got it and ran it through CPUZ it already appeared the same way, just numbers in the board identification.

I updated the bios one by one, until I reached the latest version, I did both the normal update process and USBflashback and the same problem remains.

I reinstalled Windows and it also remained the same.

I did a lot of research on this problem and didn't find anyone with a problem even similar to mine.

Thank you very much in advance for all your help, I hope we can find a solution to the problem. Thank you very much.

Hello, @Caikera 

I have compiled your case and consulted the relevant department for further verification.
Could you also help confirm the following information to help us better understand your setup?
- all the BIOS versions, OS versions, and OS builds you have updated to and with the same issue
- the brand and model name of the CPU, GPU, RAM, SSD/HDD, and PSU currently installed

Thank you in advance for your patience.

sharing complete hardware info & software config details will help us better understand the issue 🙂

Hello @Caikera 

After further consultation with relevant personnel, based on your scenario description, we believe that the Desktop Management Interface (DMI) has been altered, causing the system to fail to identify the model correctly.
We suggest sending the motherboard for repair, where the BIOS can be re-flashed at the repair center, and then verifying if the issue has been resolved. 
If necessary, please contact your original purchase platform or the previous user. 

Thank you.

Hello my friend! @Jiaszzz_ROG 

Thanks for the answers.

Unfortunately I'm no longer in the United States, where I bought the motherboard. I was on a walk and decided to buy it. I live in Brazil, so I cannot send the motherboard for return or repair, even though it is under warranty.

Is there any way to do this remotely or if you tell me how to proceed, I can do it right here in my home.

Thank you very much in advance for your great help!

Hello, @Caikera 

Besides the system not displaying the correct model, are you experiencing any other issues?
It has been confirmed that a tampered DMI can cause problems with driver installation or updates and can only be fixed by re-flashing the BIOS at a repair center.
Therefore, we recommend sending the motherboard back to the U.S. or having it repaired during a visit to the U.S.

Thank you.

I achieved! @Jiaszzz_ROG 

After a lot of research I found the tool to make the changes.

From what I understand, the previous owner made these modifications due to a ban on online games, changing all the serial numbers on the motherboard.

I used another motherboard to return all data to factory settings.

The name of the tool is DMIEDIT. It was difficult to obtain, whoever is interested better find it at their own risk, as I believe it is not in accordance with the forum rules to make such a tool available.
