how to enable ram 2n on gigabyte? is it channel interleaving or rank interleaving?

tried G.skill manual ram settings, didn't work, booted into Windows sure but ram speed and timing is still 2133 mhz.

I guess new better BIOs is needed. what is it that Joker got his ram to run at 3000 mhz that i can't? What's the specific setting? OR he got amd optimized ram, whereas mine is from Skylake carry over.
