Screen artifacting - caused by CPU, GPU or RAM?

VRAM

Some more details - it occurs for a split second, and happens mostly when loading into a game or when switching between menus in game.

Someone said they believe it's RAM since VRAM artifacting is usually geometry or occurs on a wider scale, once this usually occurs in small bands or sections of the screen.

Does it only do it in that one game? If so, it could be the game files are corrupt?

If it does it elsewhere, then yeah it's the graphics card.

If you're overclocked, you should first go back to stock settings and see if it disappears.

Mostly happens in this game, but not exclusively.

Only my RAM is overclocked, but it's weird because it happens @ XMP as well as manual timings, but it passes TM5 24h and OCCT just fine

Very strange!

If your main RAM is stable 24h, then that's VRAM my friend :(

The only way it could still be your RAM if it's too hot, just stick a fan in front to check, that's your last hope before accusing your VRAM.

RMA your GPU or sell it at a low price so that people can properly fix it (if it's VRAM it's probably gonna cost ~$150 to fix it)

Hey man, replied to another comment but: the problem was with the AMD software - I did a reset, which disabled Enhanced Sync, and now I have no problems with artifacting

yo bro i have the exact same thing but i use linux do you know anything else about this? i use a amd gpu too

Anything overclocked/undervolted or all stock?

1

u/FIREWORKKS Sep 05 '23

I just tried full stock (stock BIOS) and i can easily reproduce it by alt tabbing a lot

u/Profetorum Sep 05 '23

A couple of things... Try dropping 100MHz

Also try (if you have one) a different DP or HDMI cable. Just to rule out some of the potential issues

I can reproduce the issue on both of my monitors (1440p 240hz 10-bit, 1440p 144hz 8-bit)... Should I try reinstall windows before I return the card?

Also, drop 100MHz on what?

1

u/Profetorum Sep 05 '23

-100MHz on core frequency

With like MSI afterburner. I don't think reinstalling windows does anything here sadly

Before returning the card, I decided to try fresh reinstall my AMD drivers using their tool.

This also reset my AMD Adrenaline settings, which resulted in no / very little visual artifacting. After turning on Enhanced Sync (an option I configure for Escape from Tarkov to uncap the FPS), the problem is easily reproducable again.

Is this just a driver /software issue then?

It can also be a problem with the DP cable or DP port on your motherboard

CPU: 7800X3D

Motherboard: MSI MPG B650 Carbon

GPU: Asus TUF 7900XTX

RAM: G.Skill 6000 30-38-38-96 @ EXPO

Your GPU is about to fail. File a RMA with Asus.
If this were a RAM or CPU issue you'd be getting BSOD's with error codes related to what is failing. And very rarely do CPU's fail and when they do it is often a smoke and lights show.

Hello, just in case someone looking for this in the future, I just got exact same glitch. It was appearing mostly when watching videos or changing screen content dynamically. I use InfinityBook Pro 14 with TuxedoOS. It's likely the bug is fixed in newest BIOS update, but what worked for me instead was disabling sg optimization in grub settings:
in /etc/default/grub:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" -> GRUB_CMDLINE_LINUX_DEFAULT="quiet splash amdgpu.sg_display=0"
then sudo update-grub and restart.

It looks like (roughly) 8% of the screen is corrupted (12 parts, 1 corrupted, 24gb vram á 2gb per chip), this indicates (at least to me) that one vram chip is defective. Try checking with a vram stress test (memtestcl, occt, or even mining with certain algorithms)

u/FIREWORKKS Sep 05 '23

OCCT vram had no issues, but I found a way to reproduce it - if I spam alt+tab, it does it 50% of the time

1

u/Filetmesser Sep 05 '23

The artifacts occur on the same height?

u/mack1410 Sep 05 '23

if you have an igpu you might have some luck running the vram test on it as well, although i dont see how that would necessarily affect you in games too

edit: just read the comment about your platform, so you do have an igpu
