If you're just using one card for now, use CCC 12.3. I have 4 separate 7xxx cards going in one rig without any issues. Haven't tried more than 4 though.
As for settings:
CGMiner
intensity: 7
vectors: 1
worksize: 256
kernel: diablo
MSI Afterburner
Core voltage: depends on your card (I leave mine at stock voltage)
Core clock: 1100 MHz
Memory clock: 170 MHz
Fan speed: 85%
This will yield 650 Mh/s.
I used intensity 11. Running at 673MHash.As for settings:

Default volt, 1125 core, default memory.
How do I reduce the memory speed? I tried the slider in AB, but it doesn't change at all.
I read there's a special file that I need to change in AB, what would that be?
Intensity 11 is fine, but seems to cause CPU bug with multiple cards. So I leave it on 7 with my miners.
You have to go into MSIAfterburner.cfg and change UnofficialOverclockingMode = 2. When you open AB again, it will ask you to accept, click Yes. Then you should be able to lower your memory speed and it should stick. If you want to lower it even further, close AB, go into the Profiles folder (MSI Afterburner\Profiles) and delete anything that starts with VEN_. When you open AB again, it will ask you to restart to detect default settings properly, click No.
