Just switched from a Vega56 to a RTX2070 Super, getting regular stutters

[shadowrckts]

(copying from my cry for help on reddit)

Status: RESOLVED

Computer Type: Desktop (custom, from Xotic PC giveaway)

GPU: EVGA Black Edition RTX 2070 Super, 8GB Vram, no OC

CPU: AMD Ryzen 2700x 8-core 3.7GHz, no OC

Motherboard: Gigabyte AB350N-Gaming Wifi

Bios version/Date: American Megatrends Inc, F31 5/6/2019

SMBIOS Version: 3.2

RAM: Corsair Vengeance 2x8GB (16GB) 3400 MHz

PSU: Dual PSU - CPU/System Enhance electronics Co 600W (came with PC). GPU PSU: Corsair SF600

Operating System & Version: Windows 10 Home Build 18362 10.0.18362 (clean) 64bit

GPU Drivers: Clean install GeForce Game Ready Driver 441.87

Description of Problem: I just switched from a Vega56 to an RTX2070 Super and it seems like I'm getting a noticeable (and pretty regular) stutter in framerate (maybe once or twice per second). In rocket league it's showing as a drop every other reading by about 4 fps@150fps, moving or not. It doesn't seem to matter which screen I'm operating on (4 connected, 2 disconnected through windows)

Troubleshooting: I've run DDU 3 times now (safe mode and not, twice removing AMD, once removing NVIDIA), CCleaner once, reinstalled drivers downloaded previously. Neither the CPU nor GPU seem to be going over 50C and the usage is relatively low for each (~14%).

sorry for any inconvenience, my next step is going to be checking for BIOS updates.

Edit: Updated bios to 50a, still occur on Minecraft Bedrock and Rocket League

EditEdit: I've tried Freesync on the monitor on/off and G-Sync on/off, turned the GPU power mode to performance in the control panel, set the GPU to the PhysX processor, still no dice

Someone had requested thermal/usage graphs on reddit so I'll post the imgur link here: https://imgur.com/BYQ85Y6

 

Final edit: hooked everything back up to the original power supply (now a single supply system) and it worked just fine, no stutters

The 2nd supply still powers extra fans and hard drives (couple of ssds couple hdds) couldn't get the original supply to turn on the monitor when the Corsair powered everything else so I've dedicated a fan to the old supply and gotta live with it I suppose. Did some research on the Enhance supply and apparently it's platinum rated (though it's fan is super super tiny) so I guess I'll live with the system for now thanks for the assistance everyone!

Disable Game Bar and XBOX DVR in W10. 

 

Also disable Fast Startup in W10 and restart PC otherwise it won't take effect (won't affect your boot times).

All windows updates installed?

You cound try a clean install.

Game bar and XBOX DVR were already off, but i did turn off Fast Startup and am restarting now. I'm definitely keeping a fresh install in my back pocket as a last ditch effort though (but would like to try other things first if possible!)

 

Edit: After restart the problem continues Will check my CPU cores as suggested by sorenson below!

When I can't figure something like this out I'll reinstall windows through "reset windows". I would first try limiting the frame rate in the games. Your GPU may be overwhelming your CPU with frames. Have you checked to make sure that one of your CPU cores isn't pegged to 100% while playing games?

Do you get audio stuttering playing Youtube videos or music?

Will check all CPU cores (and limit with rivatuner and will report back!)

 

Edit: It looks like one of the CPU threads is being used heavily but not high usage on any of the other cores, could this be it?

EditEdit (sorry for spam): limiting the frames with rivatuner does seem to help, though I'm a bit concerned at not being able to push 144fps on this after being able to on the Vega56

Hello!

Does not seem to be getting audio stuttering, only visual (tested on a constant note video)

Hmm this is a bit strange.. try using LatencyMon anyway and report back the results.

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.

 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.

Wait a minute why are you using 2 PSU's? the Corsair PSU is plenty to handle the whole system, could be related to the issue? and also have you tried setting your RAM to default XMP profiles? 3400Mhz is a bit on the edge for 2nd Gen Ryzen and would be unstable for most 2nd Gen systems.

I won the PC and the PSU it came with is a super weird form factor (the PC is custom but built into the back of a 32" Samsung monitor). I bought the Corsair to power the GPU (at the time a vega56) because the other PSU was overheating and a scary offbrand. Unfortunately the PSU it came with powers the CPU and the display itself through some convoluted cable routing behind some aluminum I can't get to. I did try powering the MoBo/CPU and GPU with my Corsair PSU but the PC wouldn't turn on (even shorting the other PSU with one of those 24 pin attachments).

 

Edit: Haven't tried adjusting the RAM speeds yet, but can do that next if you want.

RAM is set to 2667 and problem persists looks like I'm headed towards a refresh.

Hmm I'm not familiar with the form factor of the PSU that is included in that PC, your best bet could be to take all of that hardware off the monitor and insert it in a new standard case, your issue is a bit bizarre, it's unheard of for me to have stuttering every second without affecting the audio.

What kind of stuttering do you get? is it possible to show a video of it happening? preferably with game audio

That's not a good sign and shitty PSU's can cause a lot of problems, I wouldn't recommend you continue using it even if your PC is working perfectly, they can be destructive when they become faulty, which might have already happened.

This is a good cheap case that you can buy, but you might also need an adapter from SFX to ATX to fit the PSU in that case, I'm unsure if it would fit out of the box, or you can get a smaller case that clearly supports the SFX PSU Form Factor.

I'll take a video of my screen and will try to have the sound playing, no luck after the reset of windows.

While I completely agree it's a risk having said PSU in my system, this problem does not occur on the Vega56 GPU, strictly the 2070Super. After I take the video I plan to re-seat the card today, will get back on here after work with any updates (and the video).

 

Edit: Re-seated GPU, no luck. I'll yank everything out I can tonight (some things are literally riveted in) and try to run the whole PC (minus the monitor) on the Corsair, unless there are other suggestions before I get to that

Sending from my phone, I think I could see it on my media app so fingers crossed it shows on here! One visible one happens when I get closer to the tree, it happens very regularly every second or so but that's when it's more visible on the recording.
