My build is in both my forum profile and also here on pcpartpicker ( https://pcpartpicker.com/user/Gadolinium/saved/6fkVwP )
Looked around on some other forum posts on this issue, and even one person just gave up from the looks of it. I've got ab4x8G kit of Vengeance Pro RGB, and the 4 channels/sticks are out sync with eachother.
Just looking at all 4 sticks set to marquee, I can watch the effect start off in-sync, but then over time, they will be all out of order with eachother.
EDIT: Minor spelling issues. Want to add that the out-of-sync issue happens on ALL effects. iCue's preview always looks okay, but the effects will slowly go out of sync between the RAM sticks themselves. Even setting it to software-controlled has problems.
