Hi All,

I tried yesterday to setup a mining rig with 2 x 5850, using ubuntu 11.04, got this weird issue. when I use only 1 gpu, I get 100% utilization, but when I try to use 2, each only runs at 50%. crossfire is disabled and I'm using phoenix:

aticonfig --odgc --adapter=all

Adapter 0 - ATI Radeon HD 5800 Series
                            Core (MHz)    Memory (MHz)

Any ideas? 


Thanks!! :-)
