I have updated my AWCC to the latest version and I am unable to OC my GPU as mentioned in this video
I have an Alienware 17 R5 with an i9 and 1080OC.
Please refer to the link below where it's mentioned, the compatibility with the Alienware 17 R5.
The video goes over all features, but not all features are available to all Alienware systems compatible with the Command Center. In the case of the 17 R5, only CPU can be overclocked.

I can't always reply to PM's, if you need extra assistance visit:
laptops have limited cooling capacity so they are not allowing overclocking on them. Desktops have much better cooling systems allowing them to be overclocked much easier.
