That sounds frustrating! Based on your message on the ASUS ROG forum and the latest information about Call of Duty's security requirements, you're not alone in seeing this message even with your BIOS updated and TPM/Secure Boot enabled.

Here's a breakdown of the situation and what might be the cause:

 

1. BIOS Version Check

 

You are on BIOS version 5901 for your ROG STRIX B450-F Gaming motherboard, which appears to be the most recent version available on the ASUS support page (released October 27, 2025).

Since you have the latest BIOS, the game's message might not be referring to the overall BIOS version, but potentially to a component within the BIOS.

 

2. The Potential fTPM Firmware Issue

 

The most likely culprit, even with the latest BIOS, is a specific issue with the firmware version of your AMD fTPM (Firmware Trusted Platform Module).

  • Call of Duty's Anti-Cheat: The game's anti-cheat system, RICOCHET, requires a working TPM 2.0 module and Secure Boot to perform "remote attestation" (verification of your system's integrity).   

  • Known AMD Issue: There are documented issues, especially with AMD systems, where certain fTPM firmware versions cause errors with this attestation process, leading to the "OS FIRMWARE: UPDATE REQUIRED" or a similar message, even when the latest motherboard BIOS is installed.

 

3. Next Steps to Troubleshoot

 

Since your BIOS is already the newest one, try these steps to confirm your security settings are properly active in Windows:

  • Verify Secure Boot State in Windows:

    1. Press Windows Key + R.

    2. Type msinfo32 and press Enter.

    3. Look at "BIOS Mode" (should be UEFI) and "Secure Boot State" (should be On). If it's UEFI but the Secure Boot State is "Off" or "Not Active", you may need to go back into the BIOS and fully activate it. Disabling the Compatibility Support Module (CSM) is often required before Secure Boot can be enabled and active.   

  • Verify TPM Status in Windows:

    1. Press Windows Key + R.

    2. Type tpm.msc and press Enter.

    3. Check the Status section. It should say "The TPM is ready for use."

If all those settings look correct but the message persists, you may be experiencing the known fTPM issue. In this case, you may need to wait for a potential specific fTPM firmware patch from AMD or ASUS that targets this security verification problem, which is separate from the regular BIOS updates that focus on stability and compatibility.
