Things I learned along the way that seem to have helped:
1. Use Catalyst 13.12. The 14.2 beta drivers were very unstable.
2. Don't bother with Trixx. Install MSI Afterburner and use the settings shown on this post (link).
3. I don't know if this helped or not, but I'm currently running with the bios switch toggled up (toward the end with DVI ports)
I think I can push them a little harder, but am currently limited by power. The 1050W is essentially maxed out, so I have the engines turned down on some. Here is my screen after 6 hours of mining. I would have had a longer run time, except the power blinked last night and for some reason it didn't autostart like it should have.
Here are my current settings.
