GPU artifacting cause?
GPU artifacting cause?
Hello everyone,
In some games, my Sapphire Nitro R9 390X starts showing checkerboard patterns on the screen intermittently. This happens occasionally and isn't always present in tougher titles. For instance, in GTA 5 I’m definitely experiencing a CPU bottleneck (my FX8350 runs at 4.7GHz), and my GPU stays cool most of the time—around 70 degrees max. In World of Tanks, where the GPU works harder, it gets worse.
I haven’t overclocked the card; it’s running at the factory speed of 1080MHz. Still, I notice the artifacts. I’ve tried increasing the power limit, but that doesn’t seem to help. Lowering the clock speeds does work, though I don’t think I should have to do that.
I’m currently playing at 1440p, which means my GPU is under more stress than in most games. However, I suspect it’s not the GPU itself. I’ve replaced my previous R9 290X with an Asus R9 390X, which also had this issue (and got very hot because they lack active VRM cooling). I remember my old R9 290X sometimes did it too, though rarely.
Could there be another cause? I’ve heard checkerboarding is usually related to VRAM, but I don’t think any card I own has had problems with it.
Here’s what I have:
- CPU: FX8350 @4.7GHz
- Motherboard: Asus Crosshair V Formula-Z
- RAM: 16GB Hyper X Savage stock @1600MHz
- Power Supply: XFX Pro 750W XXX
- GPU: Sapphire Nitro 8G D5 stock @1080MHz
Any advice would be greatly appreciated—I’d love to resolve this as soon as possible.
Many are connected to memory. Would it be wise to lower the speed.
Verify PCI frequency in BIOS is configured to auto and adjust if necessary.
