2 280x's on a x8/x8 MoBo but can't get over 75% util. Is my problem that I need at least x16/x8? I've been playing with app_config but it makes no difference how I set it.

Come on, one of you high rollers knows the answer to my question. Please.

Thanks kararom,
Can you get your gpu's continuously operating at a high utilization rate?

I think Merle is asking...if you look in gpu-z do you see the gpu usage above 75% on a consistent basis using those settings?

Yes that's right. Preferably over 90%.

PCI Express works in 8x mode

Each videocard counts for 4 jobs at the same time

CPU counts another CPU projects
