SLI screen flicker or Artifacts

[Diceair]

Hi there

First let me post my system specs

i5-2500k
2x MSI geforce GTX570 Twin Frozr III power edition
Sound Blaster z Sound card
MSI z77a-G45 thunderbolt motherboard
Corsair AX850w PSU
Cooler master Sniper case with the front HDD cage removed for better airflow
Qnix QX2710 @ 60HZ/59Hz Whatever stock is. 


So I have my cards on stock clocks when connected to dual link DVI port on the monitor. When i run both in SLI I get eiter Screen flicker or artifacts in my games only. 

What i have tried
1. Changed SLi bridge (The flexible kind)
2. Changed to another SLi connector on the card
3. Swapped cards arround
4. I took out one card and then it works fine no flicker etc etc. (Tested both that way)
5. Tried a different DVI dual link cable
6. Tried different drivers from 320.xx up to latest beta drivers.
7. Tried other DVI connections on cards
8. Connecting to old 1080p monitor only with same cable and let the GPU do the scaling and everything is fine.

So as you can see I almost tried everything there is to test. Can anyone suggest me what I should do. Funny thing is when tested on my old 1080p monitor as I can remember everything was fine until I switched to my new monitor. Bare in mind there is no scaler so GPU is doing the scaling. I also ran the following and was fine untill I go into a game especially Planetside 2(flickering and green dots) and far cry 3 (artifact with either green dots or horizontal lines at exact same area), BF3 also crashes some times. Was playing BF3 one night and my screen went off then on again.

In the nVidia control panel try to run physx off the cpu instead of the gpu's.

I don't even have physx enabled in game

No but did you try it?

Yes I did. So far I tried testing each card in the second pcie slot individually and that works but as soon as I go SLi nothing works. I also updated the bios to the latest. I even swapped my power connectors for the graphics cards. I also tried ading 2 sli bridges at the same time. I swapped my sli bridges 2 times now. I also tested with brand new one out of the box. I also tried underclocking my cards by as much as 50% and also resetting my bios to defaults and nothing seems to work. I can see that the problem only occurs in full screen mode when i play games. I alos notice that it's normally the bottom half of the screen that's shaking and not the top half. maybe it's because the 2 cards aren't fully in sync with each other

Okey, go into a full screen application where the issue occurs, and move the SLI bridge around on the pins until it stops doing it.

Ok I sort of fixed it by wiggeling the sli bridge while pressing down. Thansk for the info. i can also do 96Hz and i must say 2560x1440 @ 96Hz is amazing

Good to hear that the flickering is gone :) I can totaly agree that higher fps than 60 is amazing as i have a 144hz monitor myselves :D Now mark the thread solved? :)
