Intel Motherboards : Does Ethernet Controller need Driver installation

I didn't' mean to say there was some problem with the function of my PC. The only 'problem' was the  "!" exclamation in device driver and I didn't have any knowledge about what that was for. Once I received info above on how to search for that, I discovered it is only related to Turbo Boost Max. Once I installed TBM  the "!" disappeared. 

Turbo Boost Max probably isn't going to be used for many of my programs. Maybe for video rendering. 

Booting up time is so fast so fast ! Running smoothly.

Thank you  to all on the forum for assistance on my build!
