I've installed a TPM 2.0 module on my Asus PB875-M motherboard and enabled the necessary settings in BIOS. However, after rebooting, Windows isn't detecting the TPM at all. There's a note in the BIOS stating 'O.S. will not show Security Device', which probably explains the issue. If certain Windows applications require TPM 2.0, what's the point of having it installed if it's not working? Is there anything I can do to ensure Windows recognizes that the TPM is present and enabled? Thanks for any guidance!

First, make sure that the TPM module you installed is specifically compatible with your Asus motherboard. Not all TPM modules are universal; some are designed for specific brands. You might want to double-check that it's an Asus TPM module. They usually cost around $10-15 on eBay. I had the same issue with my Asus X99 Deluxe II, and getting the right module solved my problem.
It’s crucial to ensure you’re booting in UEFI mode instead of Legacy/CSM mode. TPM will not function correctly if you're in Legacy mode. If it’s not set up in UEFI correctly, you might need to reinstall Windows after adjusting your BIOS options to enable TPM.
Right! I had to go through the reinstallation process myself because I was in Legacy mode. Switching to UEFI made all the difference.
I found something while searching for solutions that might help. It seems that a setting in BIOS related to 'Modern Standby' could be the culprit if you're facing issues with the TPM. For example, changing the Deep Sleep setting to S4+S5 enabled in the ACPI Configuration fixed a similar problem for someone else. Just a thought to explore!
That definitely connects with your issue, especially if your BIOS is indicating problems with PCR7 binding. If you're getting a message about Secure Boot and it's not enabled, consider turning that on, clearing the TPM, and even checking for BIOS updates. It could solve your issue!
Absolutely! I had to go through the same process for my setup. Just make sure you get the correct module that aligns with your motherboard model.
