    Maximus X Hero - USB 3.0 issue

    Hi

    I have just finished my new build, however I have an issue with the rear usb 3.0 ports. I have a usb 3.0 enclosure attached to one of the ports and the transfer speeds are only between 20 and 30 MB/s. If I attach the same enclosure to my front usb ports, which are connected to the motherboard header, I get 120 MB/s as expected and as I saw on my previous P8P67 Deluxe. I have updated the drivers, but I'm at a loss as to the poor performance of the rear ports.

    Has anyone else had similar issues or any ideas on how to resolve?

    Hi videodj

    Welcome to the ROG forum.

    First two things I'd try is...

    1) Update the chipset driver
    2) Update the bios

    Get these at the ASUS Support Center, select your operating system.

    Thanks, I've already updated the Bios to the latest version.

    I'll try the chipset drivers later when I get home from work. I usually only install them if there are exclamation marks in device manager

    When you plug it in the back, go to the device manager -> disk drives, find the drive, look at the properties -> policies and make sure it is set to "Better Performance"

    So I enable better performance while the drive was attached to the front ports and speeds went upto ~200Mb, which is good. I updated the chipset drivers and rebooted and plugged the drive into the rear port again and speeds are now the same as the front ports.

    Thanks for your help.
