Did you update your mobo with their drivers/utilities?
Mine also just showed 1.1 ... it was 3.0 when i read ur msg... Try running a game or benchmark and see if it increases...
When power saving, mine is PCI-E 3.0 X 16 @16 1.1. Activating the render test brings it to @16 3.0. Stopping the test brings it back to @16 1.1. You might want to try reseating your card. Sometimes i get @8 1.1 after cleaning and putting back my PC together, reseating it solves the problem
