Stuttering / Freezing on 6900XT

Hello,

I recently purchased a PowerColor Red Devil 6900XT, and noticed quickly after playing games on it that I get stutters / small freezes. I also noticed the problem is worse when playing in fullscreen.

I first noticed the problem when playing osu!, where I would get seemingly random, and clearly noticeable freezes that would very negatively affect my gameplay. I noticed the same problem later when playing Apex Legends and FFXIV.

I have searched all over different forums for people with similar problems and tried every solution I've found, but nothing has helped. I've tried updating the BIOS, changing BIOS and Windows settings related to power management, tried XMP on/off, different GPU driver versions, different registry edits, tried CPU with stock settings and locked frequency/voltage and some other things some other users have tried. I did a clean Windows install, installed only the GPU drivers, did a test in a few games and the stuttering was still there. CPU or GPU are also not even close to thermal throttling.

LatencyMon shows a 27000 usec DPC- latency spike caused by dxgkrnl.sys whenever the problem occurs.

If anyone could have any idea what could be causing this other than faulty hardware, I would appreciate the help. I would like my gaming experience to be near flawless with such an expensive card.

PC specs:

MSI MAG B550 Tomahawk
Ryzen 5 5600X
32GB G.Skill Ripjaws V 3600Mhz
PowerColor Red Devil 6900XT
Western Digital 1TB WD Black SN750 NVMe SSD

MEASURED INTERRUPT TO USER PROCESS LATENCIES
_________________________________________________________________________________________________________
The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the interrupt service routine started execution. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that event.

Highest measured interrupt to process latency (µs): 532,80
Average measured interrupt to process latency (µs): 3,170167

Highest measured interrupt to DPC latency (µs): 530,60
Average measured interrupt to DPC latency (µs): 1,262090

REPORTED HARD PAGEFAULTS
_________________________________________________________________________________________________________
Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.

NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to interrupt the audio stream resulting in dropouts, clicks and pops. Check the Processes tab to see which programs were hit.

Process with highest pagefault count: msmpeng.exe

Total number of hard pagefaults 1153
Hard pagefault count of hardest hit process: 518
Number of processes hit: 12

Re: Stuttering / Freezing on 6900XT

I'd try a higher wattage PSU and avoid Seasonic as their newer designs don't like transient spikes typical while gaming. I've been using the 6900 XT since launch and play ffxiv and never had any of these issues. I use to have similar issues when I had a Vega 64 but I found out the DPC spikes and crashes were caused by my old 850w PSU not liking the transient load spikes. I've since upgraded to a corsair HX 1200w and haven't had any of these types of issues. 

Another way to test this is to cap fps to 60 on all games to reduce transient spikes in power caused by large fluctuations in frame changes.

There was a great article on the jonnyguru forums a couple years ago where they tested this with Vega 64 and proved it out. High wattage 300w gpus such as vega 64, rx 6900xt, rtx 3080, 3090 are all susceptible to these issues unless equipped with a PSU that is more tolerate of transient spikes.

Re: Stuttering / Freezing on 6900XT

Zero Rpm

So here’s my story, i bought the Red Devil 6800xt a month back and had your exact same issues. Ended up killing the card, so i returned it to Microcenter and by crazy luck they had a ASUS Rog Strix 6800xt oc lc in stock and i bought that. Got home and installed it….same thing started happening right off the bat. So I immediately turned my pc off and did some research and found talk of this setting having issues with some OC graphics cards. Turned that setting off and no issues after i bet its killing allot of cards out there and people are not connecting the dots.

Re: Stuttering / Freezing on 6900XT

Which setting did you turn off?

Could you please share that with us?

I'm struggeling since 10 months with this issue, replaced my PSU from a BeQuiet 680W to a SeaSonic 850W and the issue remains.

Re: Stuttering / Freezing on 6900XT

Started having this problem after updating my Windows, but I might've had it before and chocked it up to an older version of Windows.. Tried a factory reset, then a DDU for the drivers. Disabled PBU for my CPU, disabled resizable bar.

 

Running LTSC2021 presently, can anyone shed some light? I imagine it's not a common problem due to low volume of these cards.

Funnily enough I also experienced it in osu!, but because of the scrolling nature of it, it's probably just the easiest to see there. Sometimes it's just microstutters, other times it's quarter second stutters. Sometimes it's fine.

Running an 850w Seasonic PSU, 3700x, 16gb Dark Rock b-die.

Re: Stuttering / Freezing on 6900XT

So after a few different tests I figured mine out at least.

Reinstalled once and I started noticing stuttering around the time I installed the AMD chipset drivers/switching power profiles. Tried uninstalling the chipset drivers and changing the profiles around, disabled the usb selective suspend and pci power savings stuff and none of it helped. Disabled pci gen 4/resizable bar, tried killing the high precision timer or whatever. Made sure windows virtualization security was off. Reinstalled GPU drivers with the AMD clean install, and with DDU. Nothing helped.

 

Reinstalled again but didn't install the x570 chipset drivers and everything was fine.

 

What's that mean? Dunno. Maybe there was something else along the way that I didn't do. But it works for me now. Good luck to people in the future that have this!

 

For reference again, I'm using LTSC 2021, balanced power plan with pci power savings and usb selective suspend off  (I need this off for my audio interface). Also to note that's not Ryzen balanced, it's the windows balanced one. I'm too scared to install the chipset drivers again, and windows has most of it packaged anyways.

Re: Stuttering / Freezing on 6900XT

Well mine's back again. The stuttering is a little different in extremity but it's still caused by the same thing as OP in latency mon.

Re: Stuttering / Freezing on 6900XT

I see you have very similar specs to me and another person who are experiencing high dpc latency.

 

Are you by chance using dual monitors with your 6900XT?  if so could you disconnect one, then test with latencymon again and report back?

Re: Stuttering / Freezing on 6900XT

I'm actually running triple monitors + my rift plugged in. But funnily enough while testing this I either fixed it or don't seem to have the issue anymore?

 

While testing the only things I changed were replacing the displayport cable for my Samsung G7, and I unplugged my speaker's aux cables (5.1 setup, and I had an optical for old dolby digital stuff). I also replaced my realtek drivers with windows default ones in device manager, but it doesn't seem to have actually switched them so who knows.

I do still have some smaller spikes, around .05ms, which are noticeable, but I could really just blame the game/a bad testing environment. It's rarer and bearable. Really I went out to fix this more because occasionally after/around the spikes I would get lasting audio distortion until I power cycled my audio interface, they seem to be gone now though.

What's odd is that I never had this issue on my LTSC 2019 install, it was clean of any spikes. I only updated to LTSC 2021 to get the improved compositing for hardware accelerated programs across screens so I wouldn't need to disable it.

 

Could it possibly be that the directx latency was related to some sort of audio drivers issues? I know there is a API for audio built in to DirectX, but I'm not sure if it would show in latencymon.
