Hey everybody , i've been OC'ing my 7970 (standard blower cooler design thing) its now at 1075 - 1375 (i dont rly see why i should OC the memory , if i should tell me why) but at the very end of MSI kombustor with the blend tests i get flickering yellow lines vertically across my screen , now is this supposed to happen at that last scene cause it doesnt happen in any of the other tests..

Please help?

Yellow must be the chosen color for MSI, as it was for RivaTuner I s'pose.

Cut back the oc and try again. It's what oc'ing is all about.

EDIT: Frankly, running the card at stock and seeing if it happens would answer your question as to is it supposed to happen.
 
Well they aren't like real yellow , its the softer coloured and its not a straight line they're a little bit .... *Seethrough-able* Sorry im not the greatest in english... and theres a bit of that same colour yellow in the background , so it seemed normal.. but when i was in the bus going to my dad's house i started thinking: What if they were actually artifacts.... so now i can't test it till tomorrow and i just wanted to know if anybody knew

If they only occur at the end of the benchmark it shouldn't be a problem, try out some games see if its reoccurring in different applications, then you will be able to know for sure if it is artifacts
 
Run the card at stock and see if it happens, if it does its most likely fine. If it doesn't occur at stock then turn your original OC down a notch.
 
Sorry for hijacking the thread, but I have some funny problem with my new GPU. Got myself MSI GTX560 Ti along with the all other new components. I OCed Intel i5-2500k to 4.5GHz. I played BF3, Witcher 2, FSX, MS Flight, Take on Helicopters for many hours, even days and I ran in to 0 problems.

But than one night I was watching videos on YouTube and clicked to watch one on full-screen and than basically my screen froze with yellow and red pixel dots all over the place. I could still hear the sound in the background. This basically happened on my 2nd day of owning new comp. But since it didn't happen again for a week I kinda forgot about it and didn't give it much thought.

Until yesterday it happened again. My PC was on for straight 2 days, been playing games quite a lot. Temps were max a bit over 60°C for GPU and CPU. I was playing like crazy and everything was fine... until a friend called me for a game of Dota and while I was lunching it via Steam the screen froze again with same symptoms - yellow and red dots all over the screen, could hear the sound in the background for a bit (I was very quick to hit the restart button).

I would understand if this would happen while my hardware was being pushed to the max. But it happened while I was watching YT clip and lunching Dota via Steam...

Any ideas?

My guess it's a relatively stable overclock, but you're at the limit. So if you have an occasional power spike from the power grid it screws over the voltages just enough to destabilize the overclock temporarily causing a crash. Nothing you can really do about besides buying a UPS or higher end PSU, but you shouldn't really be concerned about it tbh.
 
I think the pixels all over the screen is insufficient power supply, or an unstable driver installation causing the display driver to crash. For me it was the latter.
 
I did some Googling and it turns out many people have this kind of problem with 560 Ti. And let me say again - it ONLY happens while watching YouTube. 5+ hours of gaming and it never happend. 1 minute of YouTube and it happend.

So I really doubt it has anything to do with OC or power supply.

What about Flash games?
 
OP

Give it slightly more volts (+5%) then bump it up in +1% increments till you total +12% or so. Also add a tiny fraction (+0.5-1.5%) more voltage to the memory and see if that stabilises your clock but whatever you do, do not set it to run these clocks and voltages on bootup or else if it isn't stable you won't be able to get back in to afterburner to put it back to stock!

Also: a 7970 should go a fair bit further than what you are at now.
