Does Dual Channel 2 x 8GB memory bottleneck CPU?

[Anthony Mendez]

I have 2 sticks runnign in dual channel and an extra random 8GB stick in the other lane, but this video shows that 1 stick bottlenecks the (CPU?). Am I being bottlenecked?

Also idk which are the dual channel slots, are they the blue ones?

I doub't any bottleneck just because one channel is not in dual mode. As for where they are supposed to be placed, check MB manual, "blue slots" doesn't mean anything without knowing exact MB but most of the time colors are matching the channel.
