Symptoms
1. Red/Blue and Green colored specs, or artifacts
2. Flickering of game meshes that almost resembles screen tearing
Mitigating Circumstances
1. Many have reported these problems occurring in any 90-series driver versions.
2. Many have reported these problems DO NOT occur in the 84-series driver versions.
3. In Full Screen mode, the flickering and artifacts occur.
4. In Windowed Mode (which is almost full screen except for the Application Title Bar) no flickering or artifacts occurred, but the frame rate is reduced.
User-Suggested solutions : What people have tried so far
1. RMA
This does *not* solve the problem; save everyone's time and trouble (please!)
2. Single GPU mode
Turning SLi Off resolves this issue, but is not generally acceptable.
3. Change card slots / switch the cards;
In SLi mode, this does not solve the problem. Switching to Single GPU mode does resolve the issue, per item 2 above, however is unacceptable as a solution. It does, however, prove that the individual cards are operating correctly. If you are going to touch anything in your case, please turn off the power and properly ground yourself.
4. Rotate the SLi bridge cable between the cards.
Users have reported little to no difference in the symptoms when taking this action. If you are going to touch anything in your case, please turn off the power and properly ground yourself.
5. Underclock your memory and/or GPU core clock
First off, messing with the clock timing using CoolBits, etc, is strictly at your own risk. That being said, I found that reducing the clock speed did not solve my graphics issues. If you attempt this (again, at your own risk) and elimninate your graphics issues, then this thread does not really apply to you, and you may have other system/hardware issues not covered in this thread.
6. Run in Windowed Mode
Okay, but this results in a less immersive experience than full screen, and there is a performance (FPS) hit.
7. Run the 84.21 Drivers
This resolves the issue, but you miss out on other driver improvements.
8. Remove the SLi bridge
In my experiments, this eliminates the issue, but with a caveat.
Please read on.
