I think they also prevent most CPU released before 2017ish from installing as well so computers just missing the proper TPM are few and far between anyway. You can still get around all the requirements pretty easily though.
My Ryzen 1700 system was prevented from upgrading and it met the TPM requirement, it just wasn't whitelisted. That CPU was released in 2017, and that whole gen was pretty popular (1600 sold like hotcakes). I think anything newer should work though.
That said, my primary OS is Linux anyway, so it doesn't matter, this is just an install on my other disk in case I need something Windows-specific (haven't needed it in years).
Dang. Is your board in the 300-series? Maybe it's that?
I haven't checked, but I think my 5600 is compatible. Maybe I'll check sometime, but I'm not looking forward to the mountain of patches I'll need just by booting into it again.
Your CPU is supported. It’s probably just a matter of enabling the fTPM (firmware TPM) option in your motherboard’s BIOS settings, which would satisfy Windows 11’s TPM “requirement”.
