1191329555_WeirdScreenArtifact.thumb.png.8c80247144bf86b3bcfcef2af4cafaa5.pngYesterday I was testing out the performance when I OC my GTX950 to see any difference in my working applications. Harmless checking really, then when I hit the memory clock hard as I usually do with my othe rcards like GTX1060 and 1080, I saw these appear shortly. It was weird, they moved around and didn't go away until a full restart. I've never seen em before nor do I know much about visual issues on displays. Is this threatening to my card or PC or harmless side effects of a bad OC?

 

Could use an expert thanks!

This is caused by VRAM error. If you dial memory to default and still get those artefacts, then congratulations, you've just bricked a card.

Bad mem OC. Remove the memory overclock and they should disappear.

Your VRAM overclock is simply not stable like others mentioned.

This was yesterday by the way and, indeed they did disappear after a simple restart. Thanks!

Well luckily no such thing happened. And would it still be right to call it bricked if it still functions even with the artifacts?

That won't happen since you're not increasing memory voltage, you're just increasing frequency, which doesn't hurt VRAM in any way but if you are increasing memory voltage, then you might have a chance of ruining the memory chips, but it takes a lot of effort to ruin them, you must be determined.

Though to mention, having a frequency bump will increase temperature, and in return will degrade the memory chips over a long period of time (stability), but it won't hurt it directly. (not saying you shouldn't overclock)

Honestly it's very hard to ruin an NVIDIA GPU without some modding, because as far as i'm aware, they don't allow you to change the voltage, they just give you a voltage percentage slider which doesn't seem to do anything.
