sorry for the formatting i'm on my phone

so i have a Msi Ventus 4080, and when i did the port royal benchmark i got these weird rainbow looking things when a lens flair happens it also happens in hitman 3 i did a rollback on my drivers and i haven't seen the issue since when doing a stress test on port royal which got me a 99.7 but the thing that has me worried is when i used Memtest Vulkan and OCCT vram test its saying that my vram has errors

Are you seeing VRAM errors at the GPU's stock clocks -- if you are running an overclocking tool such as Afterburner, have you attempted to return the card to defaults?

I used OCCT's 3D Adaptive GPU test to set the overclock on my card (RTX 4090), as I found it to be the best indicator of having Afterburner settings too high. I can still set them higher to run benchmarks like 3DMark with a more aggressive preset, but roll them back slightly with a "daily driver" preset for games.

I've found consistently here that if the card will pass OCCT 3D Adaptive, it will also pass Memtest Vulkan with those same settings.

If you are seeing errors at stock GPU clocks you might wish to consider an RMA.

Yeah it's the stock factory clock I decided to contact msi and did a rma thanks for the help
