leetmodz Actually it does work on 1 card, performace is quite bad but it works on single card. Once i go to two it hangs. Do you think its becouse of PSU? I really dont think it is becouse many people are mining with 2 r9 290x on 850W PSU (gold) at high intensity 900Khahs settings.

I am still very much puzzled i have tried many different pools tried everything that is based in EU only and i still get bad reports on Khahs. Could it be internet signal? At moment i am having 3 of 5 in quallity of wireless. I really dont know what else could be.

did you try both cards separately? maybe one just can't handle the config. also try upping the voltage a little bit on the one card and see if the perf goes up (stability reasons).

oh, and are you talking about pool kh/s or what is displayed on the terminal? if you making anywhere near what similar miners are making, I would just ignore it(click the "pool" button on the pool website and look for similar kh/s).

edit: ping test the pools and post what numbers you get.
