Not knowing what o/s your running, I had problems with my ccc on W7.
I am using the 5870 E6, and read that if you disable your eyefinity group, and delete all your presets, then go to the normal windows resolution set up in control panel , extend the desktop to each of the monitors then reboot.
Theoretically you should have then when you boot up a cloned desktop across all monitors, now roll back your ccc driver, , reboot
Now open ccc and set up your eyefinity config and save as a preset.
close ccc, and reboot.
This process for me worked across all of my six displays but only after using the windows resolution and extending all the monitors first then using ccc to set up your eyefinty .
I was using different display sizes at the time (3x22,2x19 1 x 21.5, and had to set every display to the same resolution of 1440x900 first then that way it was easier for eyefinity.
hope you get it sorted
