According to this site - https://basementgymboxing.blogspot.com/2014/01/fight-night-boxing-weights-list-of.html, - his 170lbs+ fight night weights included, but are not necessarily limited to: 173.6lbs vs Matriosyan 170lbs vs Monroe Jnr 173lbs vs Rubio 170lbs vs Macklin He's listed on this site as only 168lbs vs Proksa, though, as per the video you posted.
Golovkin usually weighed about 170lbs, the most he weighed was for the Martirosyan, and Rubio fights. Note: Rubio didn't make weight and greatly outweighed GGG on fight night.
