Please, explain to me what means these:

  • PCI Express Controller   

           PCI-E 2.0 x16 port #2    In Use @ x16  (MSI GTX 960 (MS-V320) Video Adapter, nVIDIA GM206 - High Definition Audio Controller)

            What means "@"?

           Also, my motherboard (Asus Z87 C) has PCI-E 3.0 x16, so maybe there is an Aida64 error


  • Device Description    nVIDIA GM206 - High Definition Audio Controller

            Bus / Device / Function    1 / 0 / 1

            What means the numbers  "1 / 0 / 1"?

1) @ x16 means it's working at x16 link width.

2) BIOS fills in the PCI-E controller registers at bootup, so in case they're incorrectly filled, it's sadly a BIOS bug that we cannot fix from our end

3) Bus / Device / Function = 1 / 0 / 1 means Bus #1, Device #0, Function #1.
