The keys aren't released if the hardware changes... heck even the bios updating is enough for the TPM to throw the lockdown on your keys. You'd need your (hopefully seperataely saved, like bitlocker tells you to do) recovery key. That's TPM 101.
Funnily enough I wonder if I had my first taste of Win 11 TPM shenanigans yesterday. It always seemed like TPM is hardly used on Win 10 and 11 outside of Secure Boot-active systems.
I didn't reinstall when going from the Unify-X to the Impact. On login, Windows threw a hissy fit about re-verifying my identity and changing my PIN. Bunch of apps needed to be signed into again. Win 10 would have needed nothing aside from reactivation.
Later I updated from 3402 to the current 3801 BIOS, and upon login Windows again prompted me to reset my PIN. It is a new board but I had otherwise rebooted multiple times yesterday without it happening.
fTPM enabled but no secure boot, so no hardware/virtualization security enabled. Pretty interesting.
I am impressed with how much voltage these boards can feed the CPU's on their own. Even at stock clocks it still gives 1.5v+ so might as well enable PBO lol..
After staring at 1.51-1.54v peaks I'm now fully convinced that the SVI2 TFN Vcore is 100% bullshit at idle. The Impact has an op-amp to switch between die sense and socket sense Vcore, and when set to die sense it properly measures idle Vcore down to about 0.3v, like Ryzen Master would. Also peaks at 1.5v or less.
The SVI2 reading I find can peak higher when PBO enabled. It honestly doesn't matter what PBO is even set to since I usually only use PBO to run lower than stock limits, it just has a higher likelihood of bogus max peak numbers.
