I have had my 460 soc for some time now, and have tried some little overclocks, but as performance has been very good, I really haven't tried to max it out.

Temps are quite low (case/cpu/gpu) and everything runs fine - except that sometimes I get weird round blobs that flash in the screen. Almost like if you get a hit in the head. Mostly this happens when playing BFBC2 for about 30mins. They're totally random in color, size and place.

I have tried many different drivers and that doesn't help, neither does tweaking of options, disabling AA or AF.

Anyone heard of something like this? Should I be worried?

Poltergeist. Ghosts are messing with you.

I knew it.

But seriously, it's quite annoying, yet seems to be harmless... Definitely not software related. Just want to know that my gfx card isn't going to burn out in a month

It's probably some sort of artifacts in the screen. Can you get a print screen of them? Try reinstalling the drivers

 

[sarka]

They don't show in video, and they're too fast to get a screenshot from. Drivers didn't help...

It's almost as if it was overheating and thus artefacting, but it is not overheating and those are no artefacts I've seen before

sounds like artifacts, what are your overclocks?

EDIT: what drivers are you using? Also go here and fill this in http://www.overclock.net/specs.php

I have it at stock now 815/1630/2000 & core voltage auto.

Underclocking or overclocking doesn't seem to do anything for those blobs either.

Do artefacts look like that these days?

They're not like the ones that you might get in furmark or atitool when going a little bit too fast...

They have a kind of "aura" and their edges are very smooth and antialiased, and in part transparent.

pixel flashes are artifacts yes. I get them when i push hard on my card and runing crysis loops. Try increasing the volts by 1 increment and see if its still there.

Bumped voltage to 1.012 and about to try it out. How high can you safely lift the voltage? Have you used fixed voltage on your card?

Currently using 266.58, as older drivers didn't fix the problem.

I use 1.212V not problem what so ever. 1.2/1.212v is just fine on most cards, specially EVGA cards. Heat will also cause artifacts after time, so bump the volts alittle bit, but remember to keep an eye on the heat.

Seems like it works. Had some blobs and upped voltage to 1.087 (can't get any more from afterburner) Requires more testing

Thanks!
