I have been mining with these cards for about 2 months and I can tell you that a number of these configs shown above are not optimal.
#1. the -w 512 setting. That just proved to give a higher stale rate. Lower it to the default 256
#2. the -gpumemclock at 1500 is too high for this card. Keep it at 1250.
#3. the -gpupowertune works ok at 20, but it can be pushed to 50 with MSI AB. I saw my card push over 900KH/s when I did the powertune to 50 in AB and not in the cgminer command.
#4. depending on whether or not you're using the gaming version, your optimal -gpuengine is either 947, 1000, or 1007.
These settings kept the temperature manageable in a cool room. Be advised, these cards run VERY HOT with peak settings.
So if you were to define everything after your pool settings, it would look like this:
-lookup-gap 2 --auto-fan --gpu-engine 1000 --gpu-memclock 1250 -w 256 -v 1 -I 20 -g 1 --thread-concurrency 32765 --temp-target 80 --gpu-powertune 20
Again, if you leave powertune out of the commandline, push it up to 50 with MSI Afterburner.
I used a few different thread-concurrency settngs, and some were great but would give 1 or 2 hw errors every 24 hours
