x399 2950x PCIe settings for LSI HBA

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I have been able to get my system to function pretty well since last nights build but my LSI 9211-8i HBA card is running VERY slow. I'm getting 8.7MB/s write speeds.
I am trying to find any information I can on the PCIe Slot Configuration and the different modes.
