I just swapped out my cpu, my previous chip had died and just received my replacement, both 5950x, Upon boot I received " New cpu installed, fTPM/PSP NV corrupted" and it asked me to reset, which I did, now im receiving the following error:

    Could this be the solution to this problem?

    Intermittent System Stutter Experienced with fTPM Enabled on Windows® 10 and 11

    https://www.amd.com/en/support/kb/faq/pa-410

    Update and Workaround

    Update: Affected PCs will require a motherboard system BIOS (sBIOS) update containing enhanced modules for fTPM interaction with SPIROM. AMD expects that flashable customer sBIOS files to be available starting in early May, 2022. Exact BIOS availability timing for a specific motherboard depends on the testing and integration schedule of your manufacturer. Flashable updates for motherboards will be based on AMD AGESA 1207 (or newer).

    Quick question though. When disabling ftpm in the bios... Will it Automatically pick up the discrete tpm chip?

    Let's face it. No one should have to purchase a dedicated aftermarket discrete TPM chip for their MoBo....period. You find anyone on the Intel side having to buy TPM chips for their MoBo's? No you do not. There is absolutely no reason an end-user should have to be forced to purchase an add-on discrete TPM chip for any MoBo when the MoBo you currently own is UEFI/TPM 2.0 certified....period. Wait until the next release when Microsoft "finally" writes their TPM module attestation to meet industry standards as opposed to sleeping with Intel.

    I went ahead and bought a damn oem genuine TPM chip even though there are bootleg ones everywhere. Will let you know if it solves all my problems or of $100 was wasted.

    My symptoms are game crashes, stuttering in any application, OBS crashing. Not sure if that lines up with anyone else, but from what I can tell it seems to be related to ftpm. If anyone has sacrificial chickens laying around... I'd appreciate any help I can get

    It's far more likely it is a combination of Microsoft's inability to get on-board w/ AMD prior to launch. It's no mystery Microsoft wrote their TPM module (attestation) with Intel and not with AMD - you only need to review/research the plethora of documentation on the Internet demonstrating both Intel & Microsoft were writing in collaboration. The ability to employ UEFI/TPM encryption & attestation should not be Intel processor specific - which it is turning out to be just the exact case. AMD & Intel most likely secure processor UEFI/TPM module encryption in vary similar manners. It's my understanding the delta resides in the fact AMD employ the best "core" CPU for running the OS & accommodating applications loaded within the OS when it boots. The best "core" may change during any particular boot operation on an AMD CPU. I'm implying that a Intel does not use the best "core" feature but instead uses the same steady configuration of each core - IOW the best "core" does not change as it does on the AMD CPU architecture. I do know the architecture is different at the hardware and software level. I don't know how the Microsoft TPM module secures the required TPM encryption algorithm to provide attestation; but, it's the attestation which fails repeatedly. These combinations are difficult to understand but it appears this is a Microsoft + AMD issue and not a Microsoft + Intel issue.

    I'm curious if anyone has noticed POST often changes during any particular BIOS boot process. One day it's one set of POST beeps & on any other day it's a different set of POST beeps. Interesting.
