So far I haven't had any stutters. Are you using the latest bios that was released?

yes

I'm starting to think that maybe the fTPM problem is linked to SHA256 OR keeping SHA-1 and SHA256 enabled at the same time. I'm testing with the SHA256 option disabled and so far I haven't had stutterings.

For those who want to test, just go to the photo option and disable one of the PCR Banks.

So far I haven't had any more stuttering.

I'm not sure if this is related but thought others here may be experiencing it too..

 

Since I enabled ftpm in the bios of my b450 mortar max (in prep for win11) on the 12th oct, this error has appeared at every boot.

In event viewer, the error appear under Windows logs, application (event id 86) :

I disabled ftpm today and the error has stopped appearing at boot.

No stuttering after windows update and latest chipset update.

First of all, I would like to thank everyone who participated in solving this problem. Disabling fTMP worked for me.

Can confirm it, no stutters after lastest Windows 10 update and AMD chipset drivers( fTPM enabled ).

Problem is not solved yet, it will only be solved when we can safely enable TPM without having stutters

Test use only with SHA-1 enabled. For me it solved the problem of stuttering.

Will try it later, need to find where to change it on my BIOS since my mobo is from MSI

Unfortunately, didn't work for me. (MSI B550 Tomahawk, 5800x.)

Same here but X570. Also on latest cumulative Windows Update for Win 10 Pro.

I also have a stuttering error in Windows 11 with tpm. I have disabled it for 2 weeks and have not had the same problem again. I have a ryzen 5 3600 and ASUS b450 pro gaming. Is the error already solved?

It is solved for some people. Try updating BIOS and installing latest chipset drivers.

I just updated to my latest BIOS and turned ftpm on, hope it doesnt stutter

the problem is on enabled fTPM, of course it wont stutter if you disable it..

The tpm is ON as i stated, its also been about 3-4hours and for me the stutter was very constant, i got nothing so far. Will keep you guys updated.

[Kirut]

I confirm that I have returned to have the same problem with the TPM. Install the latest chipset drivers but everything remains the same

This worked for me.

 

SHA-1 PCR Bank: Enable
SHA256 PCR Bank: Disable

Need to activate fTPM, save and restart PC and enter bios again.

[Kirut]

okay thanks

Hello. Just confirming that I have this problem on Windows 10 Pro. I have not updated to the latest BIOS. It could be that Windows updated my chip drivers automatically, dunno. Windows update is up to date.

 

In preparation for Windows 11, I turned on the fTPM in the BIOS. Since then, I've had the stuttering problem. It occurs two or three times a day. 

 

I wasn't fussed either way about Windows 11. I'm looking forward to it, but I'm quite happy to wait till a few patchs have been sent out before I upgrade. I just turned the fTPM off. 

 

Spex:

Aorus x570 Aorus Elite

Ryzen 7 3700 X

Windows 10 Pro

32GB RAM

RTX 2070

 

Someone mentioned Intel WiFi in a previous post. I do NOT have Intel WiFi, but I do have an Intel l211 chipset onboard wired network chip. 

[Tea Monster]

I just checked and I don't have the fine-grained control of the fTPM options. 

Until AMD/Aorus/Microsoft get their poo sorted out, this option will remain firmly OFF and I'm sticking to Windows 10. 

[dpeter]

Just had another stutter, i just changed my SHA-256 to disabled and enabled SHA 1, hope it works

Did you check within the Trusted Computing submenu there? The other controls might be buried there. In any case, it doesn't seem like SHA-1 fixes this. The only people who've reported an improvement are on ASUS boards, and I've got a feeling it's not actually fixed for them either and there's some sort of placebo effect going on there.

Yes. I didn't have any controls available for setting the PCR banks. According to others, it might have been available if I actually enabled it and restarted, but I didn't do that. 

 

I double checked the effect now that fTPM is disabled by watching a movie on the machine and in the same time frame where I would have experienced two stutters, there was nothing. The video played flawlessly with fTPM turned off. 

 

Also, I just want to add something. Someone has stated "Why isn't this noted by others who have these boards?" I initially thought that my hard drive was dying, or that I had some memory problem. By luck, I remembered that I'd enabled fTPM on the board a month ago and made the connection. How many people haven't made that connection? How many people are currently swapping out parts, reinstalling the OS and adjusting memory settings right now trying to fix this? How many people are just assuming that their internet buffered their streaming movie and have been ignoring this? This could be a HUGE problem that we are only seeing a section of here.
