Alright, well my pool hash rate got better now, close to about 60% of actual hash rate.

I have further problem which is my actual hash rate, i am can run 600khahs and max intensity 15. If i get intensity 20 on both GPUs computer freezes.
Also very wierd it is if i use settings that are suppose to be best for r9 290x   (--thread-concurrency 32784 -i 20 -w 512) i get only 80Khahs??? I have AMD catalyst 13.11 beta 9, should i get never drivers even that those are reported to be the best for r9 290x?
