TPM 2.0 support and Windows 11 (intel)

As Win10 support is ending this year, I was looking to update my PC to Win 11 and came across this thread. While the intent of this sticky is good, unfortunately I find the OP to be quite inadequate. I immediately had follow-up questions, such as, what is the exact meaning of "it does not support TPM 2.0?"--does that mean natively, out of the box, the board does not have that capability built in? But what about all those TPM modules all over eBay? Are you saying that such a board will NEVER support TPM 2.0 even with such a module?

If anyone else is still looking for help with such questions, and is confused like I was, hopefully the following will clear things up.

Firstly, ASRock has a helpful page to tell you exactly which version of TPM your board is compatible with:
https://www.asrock.com.tw/mb/spec/card.asp?Model=TPM-S%20Module&cat=Support

If your board is on that list, then you need to buy the corresponding add-on TPM module to enable TPM. (Unless maybe if it's built into your CPU? It could be that the board has a discrete TPM module, but the CPU also has it built in. My guess is that could be the case for some board/CPU combos. Not sure.) The "»TPM-S Module" link lists approved modules for ASRock.

However, if my understanding is correct, TPM 1.2 and 2.0 are not compatible, and it's a hardware thing. So, I believe that means that a BIOS update can't make a board designed for 1.2 compatible with 2.0 even though the pin layout may be the same. In any case, if your board is listed in the 1.2 section in the above link, there's no point buying a TPM 2.0 module for it as it will not work!

However, TPM 1.2 is still okay for installing Win 11 with just a bit of registry tweaking.

I found a TPM 1.2 module for my H81M-HDS, and it works. If you need such a module, you better hurry because it looks like they have almost completely disappeared from the market due to low demand. The one I got is from Authikey, and it uses a different chip from the one listed by ASRock. Looks like the "officially supported" 1.2 module, with the Nuvoton chip, has been discontinued everywhere.

Here are a few articles that provide good summaries about TPM and Win11.

Hello,

I have here three ASRock Intel motherboards with integrated processor: N3150M, J3160DC-ITX and Q1900-ITX. As all these motherboards have 17pin TPMS1 header my intention was to add TPM 2.0 chips, so I ordered them.

All three TPM chips are working without any problems on N3150M and J3160DC-ITX. However, Q1900-ITX is problematic and none of the TPM chips work on this motherboard.

I tried to update BIOS and made sure BitLocker is turned off. But problem must be in BIOS, on Q1900-ITX in BIOS\Advanced\Trusted Computing when I enable Security Device Support is says Current Status Information SUPPORT TURNED OFF.

I can also add that on N3150M and J3160DC-ITX color of the BIOS is blue/black but on Q1900-ITX brown/black.

Any ideas please? Can we expect that BIOS supporting TPM 2.0 will be released if there is TPM header on the motherboard?



I can see the same question here in German https://forum.asrock.com/forum_posts.asp?TID=34496&title=suche-bios-mit-tpm-2-0-modul-fr-q1900-itx

I'm having problems as well with Z97 Pro4.

I am having TPM 2.0 module issues like most in this thread. Mine is on an H81M-HDS version 1.05 with bios 2.30 currently. Can anyone shed some light on this here or in my thread - https://forum.asrock.com/forum_posts.asp?TID=44801&PID=127550🈾

Per the other post on this forum (https://forum.asrock.com/forum_posts.asp?TID=19692&title=windows-11-installation-compatibility) about how to prepare an ASRock mobo for Windows 11, I disabled CSM and then enabled Intel Platform Trust Technology. I restarted after each step. After I disabled CSM and restarted, the computer booted normally. After I disabled Intel Platform Trust Technology and rebooted, the computer said, "Preparing Automatic Repair" and gave me the option to "Continue," "Troubleshoot," or "Turn off your PC." When I chose "Continue," it would not boot and returned me back to the same place. So, I am forced to choose "Troubleshoot." I've been stuck in this loop and can't find a way out besides returning the UEFI settings to default. But then I can't pass the Windows 11 Health Check because TPM 2.0 isn't enabled. I've also tried changing the "Physical Presence Spec Version" from 1.3 to 1.2 based on what I saw in this YouTube video: https://www.youtube.com/watch?v=QCqgOsiQrXg. That had the same effect of preventing the computer from booting. I'm out of ideas. Can anyone help? Both my mobo chipset and CPU are on the Win 11 supported list.

The bios for your unit is from the CyberPowerPC group. You would be better served at their support site.
