It’s not so much the number of sticks as it is using 8GB and not 16. Having one quad channel kit with lesser timings than a dual channel isn’t worth a hill of beans if you can’t get the dual channel to work correctly. There have been multiple write ups and testing by members here showimg anything past 3600 is a waste of money and often you can find 3200 C14 that will outperform the 4000 C19, provided you can get the 4000 to work. Also on pricing supply and demand comes into play. If the kit you think is lesser of the two costs more chances are it’s more popular. In the end if the RGB functionality is the priority what’s it matter?*
At OP if you have the ability to swap out your 2 x 16GB for 4X 8 GB I would do so. Keep in mind that you need to buy a kit and not two packs of 2 sticks. Never mix and match kits. Almost guaranteed to have issues. The faster it is the more likely the problems will be. *You money would be best spent on a slower kit with less latency. I bought a 64 GB x299 kit Corsair dominator platinum 8 x 8GB quad channel 3800 C19 that will run at XMP all day but I dial it back to 3600 and C17 and always after any OC is finished. Memory is the last thing you want to dial in or you may be chasing your tail on a CPU OC just to find the memory timings we’re holding you back.*
If you can find a kit that is marked specifically for use with your chipset you will have the best results. *
