Update the BIOS/UEFI for your exact motherboard model because AMD firmware TPM (fTPM) firmware is normally delivered by the PC or motherboard manufacturer, not through a standalone Windows TPM updater.^1^
Install the applicable update
- Identify the exact motherboard model
- Press Windows key + R, enter
msinfo32, and press Enter. - Record BaseBoard Manufacturer, BaseBoard Product, and BIOS Version/Date.
- For a prebuilt PC or laptop, use the computer manufacturer and exact PC model instead.
- Press Windows key + R, enter
- Protect encrypted data before changing firmware
- Search Windows for Manage BitLocker or open Settings → Privacy & security → Device encryption.
- If encryption is enabled, save the recovery key somewhere outside this PC and, if the manufacturer’s BIOS instructions require it, suspend protection.
- Do not clear the TPM merely to change its version. Clearing it resets stored security information and can disable the current Windows Hello PIN until it is configured again.^2^
- Download the BIOS only from the manufacturer
- Open the support page for the exact motherboard or PC model.
- Check the available BIOS/UEFI updates and their release notes for wording such as AMD fTPM, TPM firmware, security processor, AGESA, or attestation/security compatibility.
- Use only an update explicitly intended for that exact model and hardware revision. The same
[IP Address]Call of Duty case was resolved by installing the manufacturer’s BIOS update.^3^
- Apply it using the manufacturer’s documented method
- Prefer the motherboard’s built-in UEFI flashing utility when its instructions provide one.
- Keep the PC on reliable power and do not interrupt the update. Installing an incorrect BIOS or losing power during flashing can prevent the system from booting.
- After the update, load only the settings required by the manufacturer. If fTPM was reset to disabled, re-enable AMD CPU fTPM using the motherboard manual.
- Verify the same version field Call of Duty checks
- Open Windows Security → Device security → Security processor details.
- Check Manufacturer version. This is where Windows displays the TPM manufacturer and version information.^1^
- Restart Windows, then run Call of Duty’s attestation check again.
If no suitable BIOS is available
Do not install a BIOS from another model or a third-party TPM updater. Contact the motherboard or PC manufacturer and provide:
- Exact motherboard/PC model and hardware revision
- Current BIOS version
- TPM manufacturer: AMD
- Manufacturer version: [IP Address]
- The game’s requirement or attestation error requesting
[IP Address]
Microsoft’s guidance is to obtain compatible TPM firmware and installation instructions from the device manufacturer; if no update is offered, only that manufacturer can confirm whether one is planned for the model.^1^
