Description of Original Problem: Artefacts while benchmarking with 3dmark directx raytracing feature test and playing Pax Dei. (New computer)

Troubleshooting: Initially had time spy and Pax Dei crashing with the error
Fatal error: [File:D:\tc_work\f667cdf70eb90d0e\UE\Engine\Source\Runtime\D3D12RHI\Private\D3D12Util.cpp] [Line: 873]

CurrentQueue.Fence.D3DFence->GetCompletedValue() failed

with error DXGI_ERROR_DEVICE_REMOVED with Reason: DXGI_ERROR_DEVICE_HUNG

I fixed it by setting minimum gpu frequency in amd adrenalin tuning to 1600Mhz(didn't touch anything else).
Used previous bios version, current bios version without the amd adrenalin software, memtest86x, other benchmarks run fine now (firestrike, time spy, heaven).

Main question:
Does this mean my ray tracing cores are broken, my whole gpu is broken, expected behaviour, or is it some software bug?

You can use unigine superposition to test. You may have some isntability. Try this things, put rour rams without the DOCP ram profile enabled and see if it resolved, also dont OC your CPU just to see if it resolves, use the optimized defaults.

Usualy the problem is very simple an is just someting corrupted on Windows, the easy way is isntalling Windows again.

I have also to ask, your GPU is connectd to the PSU with separated power cables?

Rguz126

Yes it is connected with separated power cables. 2 caveats to this:
1) it is done with the second connector on the power cable. (Like it has the first connector closest to the psu side and the second one furthest away). I don't suppose that could make a difference? (I did it so I could do a bit cleaner cable management and route the cable through the backside of my case instead of in front of the gpu)
2) the power cables are plugged in next to each other in pcie cable entrances on the psu (it's a modular one). Don't think that can cause any issues?

I have already tried with both pbo turned off and xmp turned off too.

Thank you I'll run Unigine superposition, MSI Kombustor, and reinstall windows and see if it stays. If it does I'll rma the card and see if it still happens. (Or if I can make the error occur on a less damanding game or stresstest I could use my old r9 280x to see if that one has the same issues).

Yes power cables can cause instability isues if not separated, is a com n isue that is known for a time and you can see people talking about that every group. Let whe know if you solved the isue

Rguz126

They're 2 separated power cables but they're plugged in next to each other to the psu. I'll move them further way and plug them in the first and not the second connector on the cable.

DreSmart

Is ok, they just need to be separated because each cable consumes their amount of power is importante because your card consumes alot. Being close ir not is irrelevante.

Rguz126

Yeah it was like that. Ran unigine with no issue, all 3dmark suite benchmarks are fine except the DirectX Raytracing feature test and a singular game Pax Dei where the benchmark has these artefacts and the game running messes my computer up and produces these kinds of artefacts. I don't have other new heavy games though. (except maybe bg3 which I am downloading now to test tomorrow) Edit: doublechecked and made sure all power cables were plugged in correctly and properly.

another demo/benchmark you can use to test the raytracing: https://store.steampowered.com/app/1691400/The_Market_of_Light/

Since my new graphics card arrived I can confirm it was a hardware gpu issue, thanks for the help.

Nice

It seems it can run stuff well at the beginning, but some sort of game/pc usage makes my graphics just become totally artefacty. But it doesn't show in any benchmark or stress test. Installing windows 10 to check if that is the issue. Edit: I'm RMAing my card, more artefacts show up on previously fine games indicating more issues behind the hood. (and games it really shouldn't, stable games for like years and years).

Run MSI Kombustor with "artifact scanner" check box enabled. If it says 0/0 after 10 minutes the main rasterization section is working fine. No idea how to test if RT is broken, though. I'd just download more RT games, and make sure driver is up to date. Maybe there is some free games with RT available. But I can't think of much other than Fortnite. Trying to think of games that don't use UE5.

if it isn’t consistent with only RT then it could be the pcb on the GPU that goes into the pcie slot on the motherboard or could be motherboard pcie slot itself. if you try it in another motherboard and it’s still happening the gpu could be dying. artifacts are a red flag for a gpu’s lifespan.

Have you tried another RT application/game?

Rguz126

No, I don't have RT games actually, just Pax Dei which had an issue and FSR enabled (no ray tracing), and then I found the same issue in 3DMark directx raytracing benchmark.
Edit: kind of seems to pop up now everywhere when I launch certain games.
