You should be able to disable RGB settings through the system settings or BIOS menu.
Don't be concerned, everything should be fine as long as you don’t alter settings haphazardly. You can always reset it if needed. It might be a good idea to get comfortable with it now, since you’ll likely want to reach its maximum speed in the BIOS. I’m not sure if the system retains settings after removing the software—someone else may have more insight on that.
I’m fine with the RAM running slower because I don’t play games much. The difference between 2666mhz and 2933mhz is not too significant, I believe. Thanks for the details!
