Quick question, can unstable overclock alone cause space invaders on RTX cards?

[Chen G]

I have a 2080ti I got used, which worked fine but I had just experienced an instance of space invaders artifact and had to reset the computer.

I was running a +1000 overclock on the VRAM but here's what I'm not yet clear on, what exactly causes the space invader artifacts? Can it happen purely as a result of unstable clocks, or does it always indicate a hardware fault?

can be caused by unstable overclocks yes.

now I'm at stock clocks, but when I launch any game the display the game is on looses signal and I have to unplug it to get it back and the game will have crashed from some directX error.

Try running DDU and retest.

I am not 100% sure if the "space invaders" thing you are talking about is specific to RTX cards, and specific to them being bad. But..... RAM OC's that are not stable usually cause artifacting, yes.

 

1000+ on the RAM is a lot... Dial it back to ~600 and see if it happens. Then slowly up it, run a benchmark like heaven valley for a few hours, up it again by ~100, repeat until its not stable anymore (or causes artifacts), and then dial it back until its good. Then maybe run it ~25 MHz bellow where it doesn't present issues.

I believe the "space invaders" is a reference to the early 2080ti's that would bug out and crash from bad ram. Similar to something like this:

I did a clean installation and now it works fine again.

 

I'm still a little worried because I've had other 2080ti before and I've failed overclocks on them many many times, I don't ever remember seeing space invaders. It's always driver crash or the game itself starts to glitch out like MW would have a black hole expanding from the center until it cover the entire screen, those kind of software level stuff.

 

full screen and system wide glitch like space invaders really worries me.

Just to clarify, looks exactly like this:

mine is indeed Micron memory.

If it happens again under stock conditions, then the memory will indeed be faulty. Since most cards carry a 3 year warranty, you could reach out and inquire about an RMA as many will transfer warranties when the card is sold.

but I put a water block on it...

It's from ASUS BTW, if that makes a difference.

 

I have RMAed a totally dead one from MSI before but I didn't disassemble and put water block on that one.

Depends on where you are located at and what laws you have to protect yourself. Like here in the US, they can not legally enforce the void warranty if removed sticker. As long as you can return it to its factory condition, shouldnt be an issue and likely will never know.
