Hi,
its your main problem solved ?
My Ideas,
280 and 290 cards in one system have one big problem - the gpu threads ( variable -g 1 or -g 2 )
- for the 290er card you need to set it to -g 1 and for the 280er card need to set it to -g 2
I have 3 rigs a two card, two with 2 x 290 and one in mixed mode ( 1 x 290 + 1 x 280 ), all cards Sapphire branded AMD Cards.
To solve the problem with the gpu threads i use Multiminer and set for each card a coin configuration. In Multiminer you can set for each coin different configs and gpu threads, thats with cgminer not possible!
Here are my 280er settings:
-I 13 -g 2 -w 256 --thread-concurrency 8192 --gpu-engine 1070 --gpu-memclock 1500 --gpu-fan 85 --shaders 256

and here are my 290er settings:
-g 1 -w 256 --lookup-gap 2 --thread-concurrency 28646 -I 20 --gpu-fan 85 --gpu-engine 1000 --gpu-memclock 1500 --gpu-powertune 20

I hope you can use my infos.
