AMD fTPM causing random stuttering.

Recently I turned on the fTPM on my asus B550 wifi motherboard because of the new Windows 11 TPM 2.0 requirements, after I did that I started getting random stuttering on everything, heavy cpu or gpu load don’t seem to trigger it, I tried running the heaven benchmark and doing some heavy renders in blender but nothing happened , its just random and everything stutters, discord calls, games, YouTube, it happens randomly at least 3 times a day

 

I turned off fTPM and the stuttering went away, anyone have a clue what could be happening? I have a 3090 and a 3900xt

which ASUS b550 wifi motherboard is this? TUF gaming or ROG Strix? 

the tuf gaming has a TPM header. you would do best with buying the TPM chip to go in the header instead of using the fTPM because the Firmware TMP probably steals clock cycles from the CPU if i had to guess. whereas dedicated TPM hardware does not.

We can't Benchmark like we used to, but we have our ways. One trick is to shove more GPUs in your computer. Like the time I needed to NV-Link, because I needed a higher HeavenBench score, so I did an SLI, which is what they called NV-Link back in the day. So, I decided to put two GPUs in my computer, which was the style at the time. Now, to add another GPU to your computer, costs a new PSU. Now in those days PSUs said OCZ on them, "Gimme 750W OCZs for an SLI" you'd say. Now where were we? Oh yeah, the important thing was that I had two GPUs in my rig, which was the style at the time! They didn't have RGB PSUs at the time, because of the war. The only thing you could get was those big green ones.

I turned fTPM back on to test and the stuttering came back, it seems to happen more often while doing multiple tasks like streaming while playing a game or working in blender while watching videos.

I still have no idea how to fix this, I don't think my motherboard has the socket for hardware TPM.

 

I've been searching around and there is barely any information on fTPM issues so I'm kinda out of luck till w11 comes out and more people start having problems

happened again but this time I had my task manager open to monitor the cpu, it was at 20%

I'm completely lost here.

20% on each core or was one core pinned at 100% and the rest at 0%? 

 

When using task manager, make sure it is set to show all cores in a separate box. If you have one box/square representing all cores, it's easy to think that you are at low usage when in fact one core it hammered while the rest are idle.

ok I'll do that, tho the stutters don't seem to be related to how hard I hit the CPU, I've tried to trigger the stutters by rendering heavy scenes in blender with the cpu but It doesn't work.
the pc only stutters 2 or 3 times a day completly at random, it will take a while before I can see some info.

it happened again, all the cpu cores were around the same workload, there was one that was a bit higher but barely any different than the other ones.
I also sent some emails to ASUS support and after trying a couple things the guy just started saying stuff like, "don't worry about w11, your motherboard can't use it because you don't have integrated wifi"..... the motherboard is a ROG Strix B550-F WIFI 🙃

 

I give up for now I'm just gonna turn off fTPM for now and wait for more people to encounter issues like these

I'm having this exact same issue with my 3900x and MSI MEG Unify x570 motherboard. I don't know if fTPM triggered it but I don't remember it happening before turning it on so I'm assuming it's that. I guess I'm just gonna turn it off for now.

so I'm not the only one.

and at least for me I'm 100% sure its caused by fTPM, I turned it off 2 days ago and no stuttering so far.

 

the ASUS support people stopped replying to my emails, not that it matters because the guy was trying to bullshit me, extra points for also misspelling "student".

if you find a solution please share.

Yeah I've turned it off for a few days now and stuttering hasn't happened. Seems like it's an issue with 3900x/xt (though if people with other ryzen processors have the same issue then please speak up!). Not looking to upgrade to Windows 11 anytime soon so I'll just leave it off.

I mean theres a reason tpm never took off in the consumer space… its old tech by now, but Microsoft wants it to happen for some reason…

Haha, good old Asus support, as clueless as ever 😄
