Video freezing with "green snow" while playing games?

post #1 of 5
Thread Starter 
Hey, so I have a SLI set up with two GTX 580's. A little while ago I was having problems with getting this freezing with "green snow" problem, and I think it just ended up being the drivers that were the issue. Now I have updated my drivers to the newest one which is 306.97 and I am getting the freezing with the "green snow" again. The only reason I doubt the fact that it is the drivers is because I recently updated my MSi Afterburner also. When I did that I think some of my settings in that changed. I couldn't remember the exact settings I had with the other one.


So my question is what do you guys think is a good core voltage for my cards? right now all the settings are:

Core Voltage: 1038
Core Clock: 772
Shader Clock: 1544
Memory Clock: 2004
Fan Speed: maxed out.

I don't mind the noise from the cards, I actually find it soothing so that doesn't bug me. What I am thinking is maybe the screen is freezing and getting this "green snow" because I have turned the fan speed all the way up? I have played around with the core voltage a little bit, but never raised it higher then 1050. Do you guys think that the fact that I have my fans running at full power could be causing this issue? Should I up the Core Voltage or anything else? I vaguely remember having to turn one of the settings up other then my fan speed to fix it last time, but I don't know which setting and to what.

Also when this issue happens, Sometimes it just freezes for about 15-20 seconds and then flickers off and then back on and it is fine. Other times it completely freezes and I can't do anything and have to turn the computer off without shutting it down. Next time it happens I will try to get a screen shot of what it looks like exactly, but until then hopefully you guys know what I mean when I say the screen freezes and I get this "green snow".

I think right now, it's important for you to test the cards at stock specs and see if they are still artifacting.

Since if that is the case, before RMA'ing (which you should do) see if one or both cards are to blame and role back to the stable driver you mentioned to see if it's still articfacting there.

If the rollback helped keep those drivers till the next NVIDIA drivers are out and then worry about overclocking.

Hi Shinigami, as the above poster has already said, the first thing is to test at stock clocks and also individually. That way, if there is an issue with just one of them you know not to RMA them both. What kind of temperatures are the cards reaching?

Thanks,

Hey guys, thanks for the response. I played around with some stuff and I bumped up my core voltage up to 1050, and it seems to be alright for now. I haven't gotten any of the artifacting. So I am going to run on this until a problem shows up. Hopefully it wont.

As for the RMA'ing of the cards, I have thought of doing that, but I don't have sufficient evidence that is actually one of the cards having a problem. Since I rolled back the drivers the last time I was having this problem and it fixed it. So like I said I guess I will just stick with this and see if anything happens, if something does then I will start to think about RMA's. Another problem is I have had these two cards for just over a year and I am not sure if I will be able to get them RMA'd. I know newegg has great customer service, but I don't know how long I have to RMA something after I bought it.

As for the card temps, they run pretty cool. I don't have any water cooling or anything, and while playing games like WoW (having the client running for hours on end) they run around 30-40 degrees Celsius.

Thanks for your responses and I will post if anything goes wrong. biggrin.gif

Great news, good to see it helped. If you're worried about the whole RMA process and being sure if either of the card's are faulty, contact the manufacturer initially to see if they can diagnose the issue. Hopefully you won't need to do that though smile.gif
