Sabertooth 990FX R3.0 won't enable TPM
I just installed a brand new Sabertooth 990FX R3.0 from Asus. I also purchased and successfully installed a TPM chip by ASUS model/part no. ASUS 90MC03W0-M0XBN1 MK TPM-M R2.0 TPM-chip. It is a TPM 2.0 compliant chip. 14-1 pins. For the record, ASUS also makes a 20-1 TPM chip which is likely incompatible with Sabertooth.
When I started the UEFI settings for the first time, I was prompted with enabling the TPM support and the TPM itself.
There are actually a few options, most reasonably greyed out when it's the first time.
So I choose to enable
- TPM support
- TPM module
There was a greyed "Pending operation" option which would be likely enabled in the future.
The problem is that:
- Windows 10 never detected the device
- Re-entering UEFI results in TPM support enabled but TPM chip disabled.
Enabling the TPM chip from the settings does not work, no matter how many times I save and reboot.
I found this very scary topic on Asus forums where they discuss an identical situation. No one got a solution yet.
I really hope I don't have to return the mobo and purchase a different model.
Question is: how do I enable TPM and then BitLocker?
Solution 1:
ASUS reported that due to a bug in the chipset's firmware, the TPM function is not available.
It will be fixed in a future release of EFI firmware. This confirms the scary forum post.
