6950 artifacting

Masterdeadly · 29 Sep 2011 at 17:45

I'm getting flashing yellow/blue blocks on my screen while playing BF3 any Idea's? 80 degrees tops which I cant see being a problem and 50 percent fan.

Try this see if it finds any problems.

Don't trust that at all i'm sorry.

Is it just in BF3 ?
If so maybe the new drivers may help.

Artifacts are related to unstable memory usually (textures are stored on VRAM). I'm running the VMT Mattbuck posted and it just stresses the cards memory. Useful.

If you don't want to run it then perhaps try running Unigene Heaven 2.5 for an hour or so, if thats fine then try the latest drivers.

is the card overclocked at all?

Masterdeadly · 29 Sep 2011 at 19:33

No the cards not overclocked but I have thought it may be because of the heat 81 degrees and the fans only at 50 percent Shall I download MSI afterburner and turn the fan to 80 percent?

iB CoMpL3XiTy · 29 Sep 2011 at 19:44

81C should be ok, wouldn't hurt to try a higher fan speed though.

I had artifacting on cs before sent it back to overclockers (RMA) Not faulty apparently. Worked fine until today on BF3

Azarathal · 29 Sep 2011 at 20:13

I have my fans on auto and dont seem to go above 60c on any game, I'll let you know what its like on bf3 later

Masterdeadly · 29 Sep 2011 at 20:14

Sigh... I cant play BF3 like this.

Masterdeadly · 29 Sep 2011 at 21:06

Fan speed at 90 percent still hitting 70 degrees a little bit of flickering on bf3 but not as much as before

iB CoMpL3XiTy · 29 Sep 2011 at 21:26

Maybe its memory overheating, I think for AMD cards you can monitor the VRAM Temps via GPU-Z.

If upping the fan speed has made a difference then its most likely temp related or could be slightly unstable VRAM, perhaps try underclocking the VRAM alittle.

ya this

Dedicated memory 850 M So that can't be it, 100 percent fan speed and max temps were 70c.

What do you meen by "dedicated memory 850 M" ?

Underclock that VRAM and monitor VRAM temps with GPU-Z

Masterdeadly · 29 Sep 2011 at 21:45

How do I underclock "VRAM" and where are VRAM temps on GPU-Z

Masterdeadly · 29 Sep 2011 at 21:45

VREG temperature 1 and 2 I've got.

Masterdeadly · 29 Sep 2011 at 21:51

Somebody I know that's very knowledge of computers says I should watercool my GPU to prevent these issues

iB CoMpL3XiTy · 29 Sep 2011 at 22:30

Yeah vreg temps is what you need to monitor. Watercooling is a very expensive way to try and solve the issue, it may not even be temp related. Download msi afterburner to change the clocks.

Masterdeadly · 29 Sep 2011 at 22:33

I don't want to lower my clock speeds. I bought the 6950 for 6950 performance.
