Abstract
Trusted Platform Module (TPM) attestation for AMD platforms with ASP firmware TPM might fail with error code 0x80070490 on Windows® systems. This issue is resolved with later versions of AMD firmware. Consult with your motherboard manufacturer and firmware release notes to determine which firmware versions contain the update.
Some applications may have features disabled if TPM attestation fails.
- Example: Gamers may be unable to compete in online cash tournaments.
Issue Details
AMD resolved this issue in TPM firmware updates provided to motherboard manufacturers in 2022.
- Some motherboard manufacturers chose not to redistribute these TPM firmware updates.
- BitLocker™ users can suspend BitLocker™ during these TPM firmware updates, which may clear the TPM outside the Windows® API. If users do not suspend BitLocker™, the computer may enter recovery mode when restarting and may require a recovery key or password to access the computer.
- See the BitLocker™ FAQ and Recover Overview for more information:
Run “Powershell.exe -Command Get-TPM” to determine if the system is impacted by this issue.
- Motherboards with AMD fTPM 3.*.0.* are impacted, where ‘*’ is any number.
ManufacturerIdTxt | ManufacturerVersion | TPM Attestation |
AMD | 3.*.0.* | ERROR |
AMD | 3.*.2.* | OK |
AMD | 6.*.*.* | OK |
Workaround
None
Resolution
Contact your motherboard manufacturer’s customer service department to determine if a firmware update is available.

I have attempted to discuss this multiple times with ASUS Customer Service (Roughly 20 different times), but they cannot give me any substantial information on when they will release a "test BIOS" for my system to resolve this issue. The responses I have received: "A test BIOS will be released before the launch of Black Ops 7 to resolve this known issue."
To clarify this whole situation: I have been talking to ASUS Customer Service about this since August, with no true idea of a timeframe of this being resolved.
My affected system:
ROG Zephyrus Duo 15 SE GX551QS-XS99
Windows 11 Pro
AMD RYZEN 9 5900HX (TPM FIRMWARE VER 3.57.0.5 [AFFECTED])
NVIDIA GEFORCE RTX 3080
If anyone has any info that could be of help, it would be GREATLY appreciated.
