Question geforce 1080 ti artifacts

[KiwiEffecT]

Hi,
I have a geforce 1080ti and when playing several games i get some strange artifacts that show up as very small black and white dots, this is particularity noticeable when rapid movement is occurring. Though it also happens when standing still and looking through semitransparent textures.
The below screen shot is of it occurring in the witcher 3, the black dots can be seen on some of the tree leaves and are generally more noticeable when the backdrop is brighter and there is movement, but youll get the idea. Any help would be greatly appreciated, thanks.

Hi KiwiEffect Always best to list your system specs with this sort of issue.

You need to test your PSU rail voltages under load or swap out the GPU with another same known working unit.
If the card is Overclocked (how) then bring it back to default frequency or try a slight increase in voltage.
Should artifacts continue after the above then RMA the card if still under Warranty.
Have you tried different drivers?

Hi MeanMachine,
Thank you for your reply. I should have posted my full specs!!!
I have an ASRock z77 extreme
i5 3570k OCed to 4.3ghz
Powered by an Enermax Naxn 650 W PSU
The 1080ti is not overclocked

I had tried updating to the latest drivers today with no success. I am not sure how to measure PSU rail voltages?

I also had this issue with artifacts playing vermintide 2, but these are the only games to be effected.

Well one of the ways to make sure is by changing your power supply to another working unit and test to see if the artifacts will be gone or not if its gone then your power supply might not be giving enough power else just RMA 1080ti if it still has warranty on it.

Your MB has 2x PCIe slots so test the card in the other slot to eliminate possible contamination in the slot or the cards terminals. You can try blowing out the slot with compressed air from a cylinder and use Isopropyl Alcohol to clean the terminals. Only do this when system is completely powered down.
The Enermax Naxn 650 W PSU has enough Wattage for your system and considered reasonably good price/performance wise. To test your rail voltage efficiency use HWInfo64 whilst the system is under full load using Cinebench as the stress tester.
Should the above tests still show artifacts then not much can be done so RMA the card.

Just some heads-up. That is an entry level PSU model. Not the very best, but it will work on your system. But, can you confirm the exact Model number once again ? Is it one the NaXn 82+ Models, or some OTHER ?

If it is NaXn 82+, then this is low-end PSU, falls under TIER D/E, as shown in this list., both new and old:

I'm NOT saying your PSU is indeed the culprit here, and even though we can't full trust that PSU TIER list, at least it gives us some faint idea of the hierarchy. Some of the info on the list is correct though.

In my opinion, this particular model form Enermax model should be avoided for stressful gaming sessions. Just my 2 Cents ! If GPU is faulty, RMA it. Else, upgrade your PSU, if need be.

Thank you all for your feedback.

I have tried both PCIe slots with no luck. I tried running CineBench but this only stressed the CPU?

Also, the PSU is the NaXn 82+. I can test my card in a friends machine (similar setup with a more powerful PSU) in a couple of weeks

Yes, please change that PSU as well, if you can. Even though, the problem might lie elsewhere, you shouldn't risk using that Enermax PSU for GAMING.
