I used the following cgminer.conf for 7970 and got 230KHPS.
I was using "gpu-threads" : "1", after changing to 2, the performance improved from 110KHPS.
But no matter what I do next, it is capped at 240KHPS. I can not increase the intensity either as the HW error increase dramatically if I change it to 14 or 15.
What is your Scrypt Sleep level?

I have 2 r9 280X and 1 7950
I use external cgminer,and it always works fine about three months.
After update the wallet software yesterday,the speed is just like before.
Here is my cgminer.conf,r9 280x got 700~720kh/s,7950 got 520kh/s:
