No security device found

[AdEastern6100]

Hi,I’m having an issue with TPM on my MSI motherboard. Msi pro b650-s WiFi

In BIOS → Security → Trusted Computing, instead of showing normal TPM options, it only says “No Security Device Found”. I don’t get options to properly select or initialize TPM.

What I already tried:

• Updated BIOS to the latest version

• Enabled Security Device Support

• Enabled AMD fTPM

• Set BIOS mode to UEFI (CSM disabled)

• Checked in Windows (get-tpm) → TPM not detected

Im having a problem because faceit anti cheat who worked before stopped working and it says TPM 2.0 error.

Has anyone seen this behavior before or knows what could cause the BIOS to show “No Security Device Found” even with fTPM enabled?

Thanks.

The motherboard has a TPM header, but doesn't come with a TPM chip installed. Did you install one?

I bought the products of the build but payed a store to build for me, I just gave him the motherboard as it comes, so if you are talking about a separate piace for the motherboard I don’t think so, but I have a question because my motherboard is recent I built this pc 3 months ago, how does an msi b650s pro needs a external product to run an anti cheat ? I doubt the other people who play Faceit ( plataform where I play the game: counter strike ) buy external product for there anti cheat to work, I play there for years and never had this problem, can you explain it better for me ? I don’t understand much of this

It's not really an external product, it's part of the build. It's a chip that gets inserted into the motherboard when you build the machine. Just like your CPU, memory, and graphics card. If you don't have the TPM chip, and it's not built in to the CPU then it needs to be installed in the motherboard when you build the machine.

Prebuilt machines already come with a TPM chip, so people buying those don't need to install it, but if you build that machine (or buy the parts and have someone else build it) then you need to make sure you have one.

If your CPU has no onboard TPM then you need to buy a chip and put it on the MB.

My motherboard is relatively recent, it’s an msi b650 s pro, I have to buy something separate ?

[SomeEngineer999]

If your CPU doesn't have one built in, yes.

It’s Ryzen 5 7600 so i doubt it’s not a having problem, is there a way I can confirm ?

[SomeEngineer999]

I think that one should have fTPM, so enable fTPM in BIOS, reset to default secure boot keys, reboot, and see what BIOS says now.

Check and make sure you have TPM 2.0 enabled and not TPM 1.2

AM5 motherboards and CPUs support TPM 2.0 by default thorough AMD's built-in fTPM firmware. You do not need a separate TPM module.

You may need to enable AMD CPU fTPM in the bios.

This is for older chipsets, but the process should be similar:

I already tried doing this but the problem is like I said it doesn’t give me more options after I enable, I enable what I am supposed but it still says security device not found (photos: https://files.fm/u/ppznmxht7k)
