My Gigabyte boards have the socket for TPM version 2.0 modules but from normal retail suppliers they disappeared very quickly when Win11 was announced. I just found an electronics company in China that makes them so I ordered 2 of them. $65.00 AU each is expensive but the rest disappeared so quickly that I had no chance of getting the normal retail ones.
Next trick will be after they arrive is if they work with the boards and CPUs that I have.
I see 116,17 skr searching TPM here ca 11.5 euro
Thats common, these are for a Gigabyte X99 board. They used to retail for a bit over $20 AUD but they just about disappeared instantly when Win 11 was announced.
