Hi guys, I've been having some weird experiences with I'm presuming my card.
All the games I play are fine with no artifacting whatsoever at 1000/1575 @ 1.093v.
Everytime I go to play a video on Steam Store, my PC instantly shows trillions of lines and different colours horizontally across the screen, now this never happened when I used my PC previously with HDMI but once I bought my new Monitor and started running Dual DVI at the same clock as mentioned it started artifacting.

Has anyone experienced this or have any info, it would be appreciated.
Thankyou,

Tom
 
Yeah wouldn't hurt. I swear I've seen someone else mention the same issue as this and it was attributed to videos also but it was fine in games, so definitely not dodgy VRAM.

Yeh, very weird as it has just started doing it and only does on the Steam Store when attempting to watch a video.

Disabled hardware acceleration and the problem still persists, also when playing a game and listening to music through Youtube it still occurs but as soon as I shutdown Youtube it stops.
I have also noticed that enabling my overclock on Afterburner when it starts up at stock it causes a flash of artifacts, is that normal?

Also I have just been playing TF2 and it randomly freezes on me playing the sound that was last present on the game over and over again until I restart the PC.
These problems never happened when I was running HDMI through the TV and now they occur when using Dual DVI to Monitor?!?

Maybe Ill test VGA and see if I come across any problems, if so then I know it is not the DVI cable, vice versa.

Right, had a go at putting my card back at stock through Afterburner and the problem went away, no artifacting whatsoever, is it a dodgy card as it is a B Grade?

Also why has the problem suddenly occured, as this has just started happening and I have had the PC built since the beginning of January?

Appreciate everyone's help, thankyou! :)

It's probably your vram overclock. As I understand it you can have a perfectly stable clock initially but over time the vram somewhat degrades. The higher you go over stock the faster this process happens. I'd suggest to go up in 25mhz stages from 1250 stock. Test it on a 'proper' game like crysis 3.
 
This exact same problem used to happen with 5850's. Overclockers had a huge sale on a batch of MSI 5850's Twin Frozr's and there was a huge thread on them. People where always getting this problem. Overclocked everyone would get it, at stock no one would.

What happen's is at stock your graphics card has different profiles for things like deskptop, video playing, gaming ect and clocks itself differently depending what you are doing.

Without an overclock this all runs fine, but once overclocked it can mess with these a little bit!

If you wanted to keep your overclock one work around would be is to put your card at stock and notice what it clocks itself to when watching flash video's. Take note of these and after overclock your card again.

Now make a profile with the clocks you noted and assign it to video playing. I Cant remember exactly it was 2 years ago when I got the 5850 but it something like this. Or leave your card at stock and make an OC profile and assign it to games.

Edit: I just found the thread... http://forums.overclockers.co.uk/showthread.php?t=18221304&highlight=Msi+5850+twin+frozr

Edit 2: Here we go, kind of ignore above... set your cards stock value's as a profile and assign this to 2D Profile and Save your OC Settings to another profile and set as 3D profile and see if this works! :)

Thank you, I'll give this a go when I get home from work and let you know how I get on. ;)

Sorry for the late reply, I tryed setting the overclock in the 3D Profile and the Stock clocks for the 2D Profile but I don't understand how it works, do I apply my overclock on Afterburner on apply the Stock Clocks?

Also when I was in-game I noticed a little more screen tearing which was probably due to the different settings. To double check I came off the game and checked Afterburner and the game had been running at my overclock speeds so don't know what that is about.

But I have noticed that when watching videos the clocks go to stock, is that what it is supposed to do?
