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? |

don't understand the question 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? |

PCI Express works in 8x mode Each videocard counts for 4 jobs at the same time CPU counts another CPU projects http://milkyway.cs.rpi.edu/milkyway/show_host_detail.php?hostid=682977 |
