<p>Above configs works fine (better hashrate) on windows 7 64, but i prefer to use ubuntu beacause windows is unstable.</p>

<p>Anyone can help me?</p>

<p>I have installed latest catalyst, sdk ofcourse.</p>

Since you have R9 290 you likely need patched Catalyst drivers as well as patch cgminer itself as described [here](http://www.ohmpie.com/mining-on-an-r9-290-in-linux/). If you already done so, then search reddit and experiment with different configurations. You should be getting around 840-870kH/s with your card.
