Thanks, that worked for me 
I am going to test your miner again soon, any idea what might be triggering the cpu usage? It is not there at the start, but after 2-3 hours it ends up using 70-80% cpu and the hashrate becomes unstable.
Im using the first version of the adrenaline driver, and I do have bios mods applied though, I have currently not tested the 1.3.7 version, but the issue is not on my test machine which only has 4 cards, that is perfectly stable, the issues appears only on my machines with 6 or more cards.
