Ok I play World of Warcraft adn have bene havign some graphic related issues. I will post my system specs then expalin what issues I am having.
Windows 7 home premium 64 Bit w/SP1
MB  AsRock Z68 Extreme 7 gen 3
CPU  i7 2600K
16GB G.Skill DDR 3 1600 Sniper Low Voltage
2X EVGA GTX 590 Classisifed
1 Corsair Force Series 3 90GB SSD
2 WD Velociraptors 450GB
Creative XFi Ti
CoolerMaster HAF 922
Corsair AX1200 Power Supply
Logitech G15 Keyboard
Logitech G500 Mouse
Everything is liquid cooled with a mix of parts from Swiftech and EK. and temps are looking very nice at around 36 deg Cel under load.
I currently have everything running at stock speeds.
 
Now the issue I am having is in WoW I will randomly get what appears to be graphical errors, not exactly like artifacts but certain features will just extend endlessly. Colors on things will occasionally just change out of the blue.  Early in the night at the start of the raid I had several lock ups of the game and I hit Ctr Alt Del to reboot it would goto the desk top then snap back tp the game and no longer be locked up. Tonight while doing a raid in Dragon Soul my screen just up and went black when we were fighting the 5th Boss. I shut down my system and completely rebooted and then had no more issues witht he game after that point.
 
Another issue I have been seeing lately and only in World of Warcraft is my graphics drivers crashing and then widows recovering them. When this happens it knocks me to the desk top and I have to restart the game. I am not sure what exactly causes this if it is poor coding on Blizzards behalf or an actual issue with my GTX 590 cards. 
 
I was running th latest Windows qualified drivers when the issue seemed to appear and after dealign with it for a few days I swapped to the latest beta drivers where things were fine for a few days but then tonight the issue started up again. All of my drivers are up to date, all windows updates are installed. MB Bios is most current from AsRock.
 
Has anyone else seen these issues and mabey know a fix for the problem it is really annoying havign my guild wait for me when I have a system that should be more then enough to run World of Warcraft with out any issues.

Thanks for the reply.
I ran OC scanner which yeilded no graphical errors and this is a copy of the log from the 2 runs i did.

It seems like it ran error free and nothign odd happened with it. I am thinking it may be Poor Programing with Blizzard.

Did you try installing an previous driver then running wow? Lol 2 590s shouldn't have a smidgen of a problem running wow, I was running everything on ultra with my 460. I have a friend with a 590 and he was experiencing problems with his 590s driver always crashing as well. If the problem persists try loading older drivers if you haven't.

Do you have WoW set to run at DX9 or DX11?
Are you cards or processor overclocked?
Did these problems just this week when 4.3 went live?
 

I have GTX580 SLI HC2's and I run WOW without issue. You can use the latest version of nVidia drivers. Here is what I did to keep WOW from acting weird.
 
*Go into the nVidia control panel.
*Create (or edit) the game profile for WOW.exe
*disable SLI performance (just for this game profile)
 
And you are done. This should fix all of your issues. Once you complete this change, you can monitor the gfx usage via Afterburner and the game still uses both cards (the use is spratic, but its there) even though you told nVidia control panel to turn it off.
 
This is something I am still scratching my head over.

I would try increasing your voltage a wee bit. In the NVIDIA cntrl panel set all of your AA, and sampling settings to the application decided option. Also try disabling all of the windows aero effect bullcrap, if not always, then at least while running the game, I know some have had issues with the NV drivers. As well as the game not getting along with desktop aero effects... Good luck, hope u get it figured out soon. Cheers

I have tried the game in both DX9 and DX11.
 
Nothing on this system has been over clocked in the matter I am looking at stabilty, what I have should be strong enough to run even the most demanding of games on the market currently.

as mentioned above try increasing your voltage on the video card a little bit. maybe +0.1V or so. i had a problem very similar to yours on my 580. i ran that game at stock speeds, but would oc (increasing voltage as well as core/mem) when playing bc2 or something (overkill). i accidently left my oc profile on one time playing wow and never crashed out when it would be at least once per gaming session (between 0.5 hrs - 5 hrs) before. i then tested with both the oc profile and non oc profile and got consistent crashing when playing wow unless i had the higher voltage. i tested with stock clocks and higher voltage and that worked as well. no clue about that one. everything else ran rock solid (games/benches/stress tests) even on stock clocks/voltage. i read around that some people had to do the same as i did (increase voltage). wouldn't hurt to try. 

aspevacek

the voltages on the GTX 590 cards are locked down because of people killing cards at release.  There was some kind of Patch applied to Wow today and it seems like it i sno longer doing lal the funky stuf fit was doing. Other then poor coding of WoW I can not come up with what would hav ecaused all the issues with my rig. I am once again able to have my Quad Sli running and play the game with out issue.

 
I'm a beta tester for Blizzard Entertainment and an active player for over seven years (I also have professional game engine programming experience). WOW's game engine is a special in-house design and at this time will not support the SLI/Crossfire technology. This question is raised at least 20 times during my course at BlizzCon every year, there is no desire or plan to ever implement the SLI/Crossfire technology into WOW. I won't go into the technical reasons why, but let me put it this way, there's really no way to bottleneck even a DX9 video card with WOW in single mode.
 
I recommend, as many before have, to disable the SLI profile for WOW itself. I can almost guarantee that you will actually see a performance increase due to driver absorption. AMD and Nvidia have tried their best to reverse the performance drop that occurs with SLI/Crossfire enabled profiles against WOW, however it's not entirely sufficient. There are still a large number of users who experience weird anomalies throughout their session--some as serious as CTD's.
 
I average on a GTX580 SC of 120-178fps in a 25 and 40 player raid with everything maxed on 2560x1600. If I enable SLI, I see roughly 40% drop in fps. If I'm lucky, after about 20 minutes my game may not actually CTD on me.
 
Anyhow, best wishes with what you do. WOW and SLI is a hot topic all over the internet, and at BlizzCon. People seem to get pissed off because Blizzard refuses to re-code the engine to support it, simply because it's not needed.

Glad to hear your up and runnung again, cheers! Happy Gaming!!

I ran (and still run) WoW with 3 580s in SLI across three monitors.  I had some graphical issues and crashes until I ran LAA (to make WoW large address aware), and ran DX11 instead of DX9.  After I made those changes, I get even performance out of each card and no problems.
I am sure results will vary.

My thing is the way my system is configured when I upgrade after the new year I will  have 2 fairly high end cards to throw in 2 back up systems if I wish. I am currently running 2 systems both i5's each with a GTX 460 in them and when I swap out the gtx 590's those rigs will get the 590's.  I do not view it as a waste of money really just getting what I wanted.

StormCipher (or anyone else that can answer), how are you getting 120+ FPS?  The best I see at any setting is around 65FPS.  I just figured WoW maxed at around 60FPS??

turn vsync off

and O/C your cpu wow is mostly CPU based processing, you will see more FPS with  good CPU then any gpu upgrade.

Also, some UI mods utterly ruin FPS, even small ones, WoW can get completely hosed by some UI addons.
Also, with higher end GPU's one thing I have seen happen, even with EVERYTHING maxed out randomly FPS will tank.
The fix I have seen is this.
1-Enable Maximum performance mode in NVidia Control Panel
2-In WoW, enable DX11
3-Turn up Multisampling to 8x and FSAA to 8 or higher
 
It will ask you to restart WoW.  This has done alot to resolve the FPS randomly tanking issue.  It will never be fully fixed, as IMHO there are some fundamental flaws in the game code.
