This is my build https://pcpartpicker.com/list/GYQVPs. first off, I can only use one stick of ram I don't know why the computer refuses to boot if I put both in and secondly I feel like my 1080ti isn't performing as it should. I can't get 60fps ultra settings in Wildlands, Deus ex and can barely maintain steady frames in pubg. Is this all because of my ram? If so what new ram should I buy?
