Hi,

i have been using the tutorial for a headless linux btc mining machine. thanks for that to dukejer :-)
i am using 3x ati radeon 5850 and my problem ist that they only run at 550MHz GPU
when i stop all off them and start only gpu0 i got 750mhz. When i start gpu1 the frequency on gpu0 changes to 550 and the gpu1 is 550mhz. this continous with gpu2. after a while all gpu's are at 550mhz. i only get 220MHash/s on each gpu and usually they are supposed to be at 330MHash/s.
aticonfig --odgc shows me this atm.


Default Adapter - ATI Radeon HD 5800 Series
                            Core (MHz)    Memory (MHz)
           Current Clocks :    550           900
             Current Peak :    775           900
  Configurable Peak Range : [550-775]     [900-1125]
                 GPU load :    100%

this is the same on all gpu's
the peak is atm at 775 but he is not using it. i am also using the usual AOD peak range.

I am using this settings:
 phatk VECTORS BFI_INT FASTLOOP=false AGGRESSION=13 WORKSIZE=128

greets
