Now, I don’t fully know what caused this, Microsoft, AMD or ASUS, but in my case on ASUS Strix X570-E motherboard with Ryzen 5800X3D, Windows 11 kept “complaining” about TPM security feature called “Attestation” being “Not supported” even though 5800X (regular non 3D) that I had before, supported it. Well, today I got notification that I have set up for my motherboard BIOS that new version is available. Okay, I check the ASUS support page and there is indeed a new BIOS update version 5003 for ASUS Strix X570-E which mentions firmware update for TPM subsystem. And that instantly got me thinking, is this it? So I made a screenshot of before and after update. And indeed, Attestation is now “Ready” the way it should be. I was also having issues with TPM just randomly not being detected in Windows 11 and after reboot, it was there. We’ll see if that was also fixed with this BIOS update. Hopefully, it is…
BIOS 4802
BIOS 5003
As you can see, the TPM firmware version now has newer date and Attestation status is now also “Ready”.
Since this is AGESA update, it means that this isn’t ASUS exclusive fix, it was sent out by AMD. Meaning if you’re experiencing similar issue and you understand why this feature is there, check out for latest BIOS update for your motherboard and update it if required. BIOS updates are good to have but usually not necessary and can brick your system so only do it if you understand how and what the risks are. Just a disclaimer.

Just checked the status again and it’s now “Not supported” again. WHAT. THE. ACTUAL. FUCK. What the fuck is this broken shit? I don’t get it. Microsoft and AMD, fix this motherfucking shit. This is fucking embarrassing.
It seems to reset to “Ready” after reboot and then goes to “Not supported” just randomly at some point. This is hilarious in the saddest possible way.
UPDATE 2:
Now it seems to stick with Ready after couple of reboots. Odd, but “knocks on wood”, it seems to remain on this now. Also no TPM Missing status anymore…
