Possible Artifacts?

[CrunchyApple]

Hey all, I have my card overclocked at 900/1800 @ 1.075 volts.
In starcraft 2 these different colored flashing circles, they would be artifacts right? I originally had the voltage @ 1.05 volts for the overclock, but I saw those circles and I upped the voltage. Is it normal to put more voltage then what I already have? I ran Furmark when the voltage was @ 1.05 volts for about half an hour and it ran fine, same when it was @ 1.075 volts (ran that one for an hour). Can anyone help?

Anyone?

what card do you have?

does the artifacts occur with NO overclocking on the video card?
normally artifacts happen with memory overclock being to high

I have the MSI GTX 570 PE and it happens when my card is OC to 900/1800 @1.05 v and 1.075 v. I haven't overclocked my memory at all.

Run furmark for a longer period of time, keep track of the temps too. If you still don't get any results, I would run prime95 at the same time in an attempt to push your computer as hard as possible to see how high the temperature rises to see if that is the cause.

I raised voltage to 1.08 and it still happens. It only seems to happen in starcraft 2!!! Why?!!So frustrating. Do you think uninstalling and installing would help?
