Incorrect motherboard info

The motherboard model that Windows tools (Speccy, CPU‑Z, msinfo32) show comes from SMBIOS data that the firmware exposes to the OS. If that SMBIOS data is wrong, every tool that reads it will report the wrong board, even after BIOS updates or OS reinstalls.

Windows and utilities are not detecting the chipset incorrectly; they are just reading the incorrect SMBIOS strings. This is similar to other cases where Windows components misinterpret or rely on SMBIOS data for hardware information.

Because SMBIOS is populated by the motherboard firmware, the only durable fix is for the firmware to expose correct values. On a second‑hand system where the SMBIOS strings appear to have been programmed for a different model (for example, a B550M board), this typically means:

1. The board was refurbished or reprogrammed with an incorrect SMBIOS configuration; or
2. A previous owner or repair shop used a tool to overwrite the DMI/SMBIOS information.

From the Windows side there is no supported way to override or correct these SMBIOS fields. Any anti‑cheat or game that flags the mismatch is reacting to the firmware data, not something Windows can change.

The practical options are therefore:

1. Contact the board/system vendor and request a corrected firmware or service that reprograms the SMBIOS/DMI data for the proper model.
2. Replace the motherboard with one whose firmware exposes correct SMBIOS information.

Windows tools will then automatically show the correct model once the firmware’s SMBIOS data is fixed.
