Press the blue question mark next to Bus Interface, do the render test, see if it increases with load.

Cheers, Jstn! it worked. I guess it justs witches to 3.0 when under load in order to save power

Yes, you are correct. PCIe link state power management is responsible.

I was asking myself the same question a week or so ago, and just stumbled on your answer in this thread. Thanks!
