fTPM activated in UEFI but Windows 10 does not allow Bitlocker Encryption

[mimosof150002cf]

Hello forum,

since i changed my cpu from AMD Ryzen 3900X to 5800X on the MSI X570 Tomahawk Wifi a fresh Windows 10 installation does not allow to encrypt my bootdrive (GPT) with bitlocker.

I use bios version 7C84v14 (released on 4th of november 2020).

I'm wondering if this is an error in the bios since it worked flawlessly with my 3900X but not with 5800X.

fTPM is activated in the bios.

Maybe s.o. can help me out. thx

It might be worth asking AMD if a ftpm is currently included in the 5000 series feature set.

It may be the BIOS or does it have to be enabled to be seen

The first image of the BIOS with the 3900X is on the beta BIOS

And it is here

MAG X570 TOMAHAWK WIFI

E7C84AMS.142

Take a look at my second picture. Bios 142 is older than 140. It was not available with both bios versions but i did not take a screenshot earlier.

Yep that the Bios after the BETA same version I am using

No 142 was released before 140 all beta end with a 1 to 9 final end with a 0

Going from V142 to V150 instead of V142 to V140 would have made way more sense and both were released on the same day just several hours apart

I said "Bios 142 is older than 140 ".

I said "Bios 142 is older than 140 ".

Fair enough but the BIOS numbering is really confusing.

 

[mimosof150002cf]

I appreciate your help.

 

[Alan J T]

I appreciate your help.

If you go back to 142 it may be working as it not showing up on mine so does not appear to be the CPU but the BIOS

I'm having the same issue with the same motherboard (MSI Tomahawk x570 wifi) and processor (5800x) on BIOS version 151. It was previously working with a Ryzen 3800x and BIOS version 120.

Did anybody have any luck making this work again?

Yes. It seems to be another BIOS bug. When I reloaded defaults, reflashed the bios (yes.. don't ask), loaded defaults again, the TPM was recognized and I was able to use Bitlocker. Not sure what triggered the bug and what actually fixed it, but Bitlocker is finally working here on the 151 bios (different board btw, B550 Carbon Wifi, but that does not seem to make a difference). The 151 BIOS has a LOT of bugs.

Good to hear that what I remembered actually works
@mimosof150002cf : you might also want to give it a shot

I flashed bios 153 and now bitlocker is working again. Thank you so much for your help guys/girls.
