Bad video memory or what?

Got a new GPU, RX 470 and this bar-code thing appears after I leave the PC idling for a while. First couple of times I just "refreshed" desktop and it disappeared, now I was able to move it around for a while before it disappeared. Everything else looks fine, games work like they should, I didn't touch any GPU settings, only the CPU is overclocked, same as it was with the old GPU. What could this be? Looks like memory artifacts to me, but IDK. Should I return the GPU?

That is video artifacting Exchange or RMA the gpu.

+1

Any chance these artifacts are software or bios related? Because they only seem to happen during idle state.

Its best to just replace it, highly doubt its anything but a defective card.

I would do it straight away if my old GPU wasn't fried. I'd have to wait probably a month to get a replacement. But I guess if that's what I have to do then that's what I'll do.

Yeah your definitely want to Exchange/RMA that. That is your best option. Does your motherboard have on board video for the mean time?

@Curlyfrii87: No, but I have a HD 4550 for "just in case".

Better than nothing >__>
