Hi,
I have a rig with a 3 x 6950 sapp xtreme. Running in Ubuntu, phoenix. The PSU is a CoolerMaster SilentPro 700w.
No matter how i overclock or the VGA, it DOES NOT move of 320-325 mhas. I can put it on 800,300 850,300 900,300 and its always the same... any idea ?

EDIT: In fact, is not a problem of the 6950, i change that VGAs for a 3 x 5850, and i cant go further 300 mhas with the 5850s... WTF?
