AMD fTPM causing random stuttering.

Apologies if I'm off track, but you currently use BitLocker and don't want to disable fTPM because of that, correct? Or am I misreading?

 

I used BitLocker on a previous machine and it bit me bad with no recovery. Never again! Veracrypt (fork of Truecrypt) is an absolute solid choice if you want to encrypt your drives. I have used it for many years. No problem disabling fTPM and still keeping encryption if that's what you're after.

Yeah, I currently use bitlocker. If I turn off the fTPM I fall back to my system needing the decryption key at startup. Bitlocker itself is fine for my needs I just need the TPM so my system can be rebooted and managed remotely. (can't enter the key remotely!)

 

I have offline storage of my bitlocker decryption keys so not to worried about that part.

 

For anyone looking I ended up finding what I needed, MS-4136 for my MSI X570.

I'm not sure what to suggest in your case. I switched to Veracrypt for whole disk encryption (local) when BitLocker let me down, and it was/has been faultless. I don't use it for whole disc encryption now, I use encrypted containers with Veracrypt and they can be mounted on all platforms/devices with a portable version.

 

If you need remote access, maybe look into Virtualbox? Not sure how that works with BitLocker though.

One thing I will point out. This is likely unrelated but thought I would bring it up because who knows. Hopefully someone can disprove this.

 

So when I first built the PC I had a RM1000x. I was learning stuff about voltages so for those 2-3 days I didn't notice this issue. Yesterday I replaced the power supply with an older RM850x as I knew that had good voltage rails to check if there was any differences to the RM1000x I had installed.

 

This first stutter (I have noticed anyway) coincidentally happened 40 minutes after putting this 850w in. There are reports of even 3080s tripping OCP on 850w PSU so I wonder if the random power spiking of GPUs is just enough to make something weird happen on the PSU/CPU momentarily? Like it's not enough to trigger OCP but it's enough to cause this issue people have experienced. The ftpm thing fixing it is just a mask. Maybe it also can't handle the power spikes from the GPU?

 

Does anyone have more than an 850w PSU (say 1000w=+) that can confirm they still have the issue?

 

Also Asus has released AGESA 1.2.0.6 so maybe this helps?

It almost always happens on the desktop when very little is going on, on my system.  Those power spikes will only happen under heavy load.  On the topic of tripping overcurrent protection though, that only happens on power supplies with overly sensitive protection circuits, of which Seasonic seems to be one of the primary offenders.

One GPU-related connection I have noticed though, is that disabling hardware GPU scheduling (something I did for unrelated reasons) seems to have reduced the frequency of the problem.  It doesn't really make any sense why that would affect this issue, but it seems to have on my system.  It's a moot point though since it still happens so I still need to disable fTPM.

Looks like I have the same stutter bug, it happens randomly I don't know how to trigger it, even with no system load just an open browser nothing else.

The sound is distorted ( sounds for me like freezes in an console emulator) and the mouse cursor hangs for ~1.5 sec.

 

I had luck to capture it on video while streaming.

Yep, looks like exactly the same thing, and the same annoying issue of what exactly is causing this? We know disabling fTPM solves it, but what is going on?

 

I read on the Lenovo forums that they dismissed a customer warranty purely based on the fact that they were not able to reproduce it on demand when they had the unit in their possession. It was sent back with the same issue. How do you reproduce a totally random stutter? If it was repeatable on demand, it would not be random.

 

Anyhow, disable fTPM and your problem will vanish.

Just curious what PSU do you have?

Yes that would be not random if it can be triggered, If I would know what Windows is doing in the background maybe then.

 

I'll give it a try after downgrading the BIOS to 3601, with the current one it's not possible to disable TPM.

Someone just shared a possible fix for this issue on reddit, if you guys want to try it

 

The fix suggests you to disable an TPM Function called "TpmCoreProvFunctionLogger", to disable this use ViVe Tool and use the command "vivetool addconfig 31621124 1" 

 

To revert back, use "vivetool delconfig 31621124 1"

[ryox]

Yep, disable fTPM through trusted computing in bios seems to "fix" the issue for now.

 

But, this is only consider as a workaround.

 

We need a real fix from AMD / Microsoft that let us enable fTPM without causing random stuttering. 

[solidsniper]

My setup is a 5900X 6900XT X570 Taichi

 

The easiest way to reproduce the issue for me is:

• Have fTPM enabled ofc.
• Have 2 monitors attached to the graphics card. DP or HDMI does not seem to matter.
• Open CS:GO on one monitor.
• Open VLC and play video or music on the second screen

On my setup stutters happen pretty much every 1-5 Minutes.

 

Disable fTPM and the stutters are completely gone.

I have test both a 3700x, 3800x, and a 5800x in the same board. Same issue. Both cleaned installs. If its CPU dependent then the fault rate is extremely high. Also dont pcie bus errons get logged in Event Viewer? There is never an entry with this stutter. 

AMD turned down AER reporting in Agesa 1.0.3 for Zen2 and later, it only logs fatal errors now.

[conr44]

This seemed to happen to me just now after installing a physical TPM module (fTPM disabled) I got the audio and video stutter, however this was while streaming from my Ryzen PC to my (also Ryzen) laptop with Windows 11 (and therefore fTPM of some sort probably). So it could be either of those, I'm not sure but I never noticed it before on the laptop.

[SilentPrayerCG]

Some of our Russia news sites made articles about this issue. Like this one https://3dnews.ru/1059041/svyazannaya-s-modulem-amd-ftpm-oshibka-stala-prichinoy-podvisaniy-windows?utm_source=yxnews&utm_medium=mobile that referring to this news, I guess, https://hothardware.com/news/bugs-in-ryzen-ftpm-reportedly-tanking-windows-11-performance

I wonder if now AMD or whoever will notice this and fix it.

[PeterK]

I have windows 10 and i am facing the same problem if i enable or switch the ftpm modes. Initially i changed it to be able to get the win11 eligibility , but now i turned it back to it's old state and f*** it . I refuse to upgrade . This is a bios /microcode level issue , no windows update will fix it . My motherboard is an asus X570 Tuf gaming plus ,paired with a 3900X cpu

Hey guys,

 

I found smt on Reddit, which has worked for me so far:

 

 

You may try and report if it works for you.

[gymleader]

Might be totally unrelated but here goes. Couple days ago this got posted as a preview build for an upcoming WIndows 11 update (I think I'm correct in stating this anyway):

 

https://support.microsoft.com/en-us/topic/january-25-2022-kb5008353-os-build-22000-469-preview-920e6297-567b-4b95-afe9-35d17de02c3a

 

I did a ctrl + f for tpm and sure enough under improvements and fixes:

 

"Addresses an issue that might cause the Get-TPM PowerShell command to fail when it attempts to report Trusted Platform Module (TPM) information. The command fails with the error, “0x80090011 Microsoft.Tpm.Commands.TpmWmiException,Microsoft.Tpm.Commands.GetTpmCommand"

I think it's nothing about AMD, just an another error from fTPM.

Well well well naughty ASUS. I've been having this issue with my X570 Dark Hero + 5950x on W10 for months and months and I can't disable fTPM at all on current or latest BIOS.

Downgraded to ASUS 3601 BIOS, disabled fTPM and re-did overclock. Everything seems fine so far

[Amaranth]

Interesting, I have yet to see an issue on any of my AMD machines under Windows 11 (running a 5950x, 3950x, and 4750U Pro respectively).

Is there a conclusive test or way to trigger the stutter? I'm curious if I've gotten lucky or if I've just missed it happening.

[TenZenRen]

Happened to me I was on Windows 11 beta and updated on thru. And I had so much background usage via userbenchmark. I ended up flashing  back to 10 and taking the update again without going thru the beta. I haven't seen any stutter even when I had the high background usage. But I auto overclock to the max it'll let me with Ryzen Master. Ol 3950x it's a brute.

Hi everyone.

I reported audio lagging/stuttering issues on my Asus G15 on reddit and stumbled across this thread a while back when trying to find a fix:

With the regedit fix and power mode modification, I am still getting random stuttering. 

Has anyone been able to turn of fTPM on their laptops? 

 

Thanks 

[Derrell]

I switched to Windows 11 and had the same issues everyone else is having to fTPM I guess as everyone else has noted. One thing that has helped me so far was turning off all non Microsoft services. I have turned three back on (just did all of this yesterday), and I am hoping to find some breaking point that make lag/flickering very bad. To my knowledge everything is up to date, but there hasn't been a bios update since last august.

Didn't worked for me, unfortunately. (5800x, MSI B550 Tomahawk)

Read this on reddit.

 

"Disabling Core isolation also fixes this from my experience.

Go to Windows Security > Device Security > Core isolation > And set to "off"

 

I decided to try it myself. Without ftPM enabled you get this: 

 

If you enable fTPM you get this:

 

 

This is super interesting. This "core isolation" can never actually be enabled if fTPM is disabled so it does give some validity to why disabling fTPM works. It's just a down and dirty way of disabling core isolation to fix the issue.

 

The thing is... I have no idea how to view core isolation. It is simply not visible for me at all.

Did someone else tried this? I even don't know what Vivetool is, and what exactly it do.
