FurMark - What Exactly Is An Artifact?

Hello Tom's Hardware!

Having had my Vapor-X HD 7970 GHz Edition for a week or so now, I decided to have a fiddle with Overclocking and FurMark testing.

I got up to 1200MHz Core and 1600MHz Memory and I saw what I know to be an artifact, a group of lines out of sync with the weird doughnut thing... :p

I really can't afford to murder this thing so I decided at that point to leave it at stock (1050MHz + 1500MHz) for the time being until I am a bit more knowledgeable about the whole thing.

Curious, I decided to run the preset 1920x1080 benchmark at stock speeds and still saw one or two little flickers.

This got me wondering:
1) Have I damaged my card?
2) What exactly is an artifact?
3) Was that very slight flickering at stock an artifact?

Any help would be deeply appreciated,
Conor

this sounds like an artifact. In my experience when the GPU first starts to have artifacts they will be in just one frame and not stick around long enough for you to even move your eyes to it before its gone.

as to you post right before this, have you tried to update the GPU driver. Make sure you are using the latest driver from the AMD web site.

If you are to worried you can back down the clocks to under stock settings and see if the issue goes away. If it does then the...

answer to 1. I doubt you hurt your card but when you OC you need to go slow and test a lot per bump up.

to answer question 2, an artifact is a graphical anomaly, A piece that is not rendered correctly. It can be many different shapes/colors from single square pixels to a large multi-sided shape with triangles.

answer to 3. with out seeing the exact thing you are referring to it is very difficult to say exactly what it was.

Well, is it possible for Artifacts to appear at stock speeds?

Okay, I'm worried now - my task bar just started flickering :-/

The best way I could describe what I saw in FurMark was a very minor squiggle/flicker out of sync with the image

If you are to worried you can back down the clocks to under stock settings and see if the issue goes away. If it does then the GPU is faulty but if they remain then it is a hole other issue to try to track down like drivers, power supply, conflicting programs just to mention a few possibility's.

What this guy said, but make sure it's the latest stable driver, not a beta, to be safe.

Thanks for all your help, I lowered the Clock Speeds down to 900 and 1400 respectively (100MHz below stock) and the problem dissapeared, I have spoken to Amazon and a replacement is being delivered :)

Note - I am using CCC 13.4
