I only use 7970's, but they worked out of the box.  I just can't use cgminer 2.11.x anything for some reason.  I use 2.10.x still.

Try a 0.57 Core:Memory ratio (570 Core to 1000 Memory is a good starting point)

Check you are not accidently CPU mining at the same time.

I made that mistake with a tick box and it killed the AMD performance due to shared openGL

I checked and i am not cpu mining at the same time.

im using this batch configuration in cgminer 2.11.4 and getting an average of 350 kh/s and that is without any voltage changes. If you dont want to overclock it at all you can take out those setting after the --auto-fan stuff

cgminer --scrypt -o yourpool:port -u yourusername -p yourpassword --intensity 12 --worksize 256 -g 2 --thread-concurrency 5120 --auto-fan --auto-gpu --gpu-engine 1100 --gpu-memclock 1450  --temp-target 66
using these settings i am running at about 290 Kh/s

any suggestions how i can modify these settings to get some more out of the card?  I feel like the card has more in it, when i run my 6870 i get 290Kh/s and use these settings

--intensity 18 --worksize 256 --gpu-threads 1 --thread-concurrency 6720 --auto-fan --auto-gpu --gpu-engine 900 --gpu-memclock 1050

if i am getting 290 out of my 6870 i should definitely be able to get more out of my 7870!

also is there a way to have one GPU run with 1 thread and another with 2.  i tried --GPU-threads 1,2 but it will not work.  says "1,2" is not a number.  i am trying to set GPU0 to 1 thread and GPU1 to 2 threads

Thanks for everyones help!

Don't forget to erase the bin file in cgminer directory each time you change your launch parameters Sad It may save some headaches !

I used them out of the box and never had any problem.
thats really bizarre that 2.10 works and .11 does not.  using the same config file from .10?
