Flickering walls in Time Spy Graphics Test 2 - Does this mean my GPU is defective?

[hsjj3]

I just got a new GTX 1060 SC a few days back. It is on factory settings.

Thing is, I have done lots of stress testing - Firestrike stress test, Furmark (20 mins), Unigine Heaven...there is no artifacing in them. Zero games that crash as well.

Only specifically in the Time Spy Graphics Test 2, I see the walls flicker, and even then not always. I have run Timespy about 5 times, it happened twice. The first time I ran a few days back, I saw it happen. I got panicked. I reran 3 more times that day after running DDU, no flicker. Today, a week later, I run it again, and I see the flickering.

Is my GPU defective, or is this an isolated issue with Timespy?

reduce GPU clock to 1500Mhz,Vram Clock to 7000Mhz and see result if you still see flicker , then yes maybe GPU is defective, RMA it.

or problem can be from DPC latency, check it with latencymon

don't use

this doesn't work in win10.

Is there a chance this is just a bug? Or no chance?

I'm kinda afraid now - if there is an issue, and I need to send it back...given the lack of stock and distance I'm going to be out of a GPU for some time then.

I'd keep it for now, if you send it in they'll probably say it's fine and send it right back. This is a new card, so plenty of time to claim warranty if you actually start noticing it in games.

Could be a bug too, in dx12 the application has much more responsibilities.

When you want to consider sending it back I'd do a more elaborate test, run timespy 15 times or something, note how many times you see the artifacts, then clock the card and memory back a bit, run it another 15 times to see if that stops it.

Funny thing is, this doesn't happen always.

Yesterday I got it twice in a row at stock settings , then I downclocked by -65MHz and there was no issue, and afterwards I overclocked by 85MHz and there was no issue either.

So it's a really weird thing.

could be temperature related.
what is the GPU temp at idle? max load during test? what is the room temp? you can use tools like GPU-Z to check.
did you set a manual fan speed curve? im asking because if you did and its too low, the GPU will overheat.

I had the same thing happen on my EVGA 1060 SC card and I posted about it a while ago in another thread. I just assumed that it will need to be some driver optimizations because the light rays aren't as transparent as they should be either. On other benchmarks, I didn't notice any other issue.
