Hello Josh,
No, you don't have to set anything. The only important thing is the dual channel (if you look at the RAM slots, it is always 1+3 and 2+4 with 4 slots).
But since you buy 2 additional slots, this is done automatically anyway, you don't have to set anything unless you want to overclock the RAM (voltage etc.).
hey, i have the 2x 16GB of these sticks running on a MSI B450 Tomahawk @3333Mhz. my cpu is a 2700X, so i'm pretty sure it will work with a 3700x as well. the Tomahawk board is a good choice, it has enough power for a 3900x.
The difference is actually insignificant, as you may have noticed, only one letter in the manufacturer number is different. This means that the cheaper version (CMK16GX4M2D3600C18) is also optimised for older chipsets, e.g. Intel Z390. Nowadays, however, this makes no real difference.
To the second question: They have identical specifications (also e.g. latency). So there is no difference in performance here. It is best to buy the bars that you like better visually or that fit your system better.
Servus.
I would choose 2 slots with 32 GB each.
Then you still have the option to upgrade to 128 GB with an additional 2 x 32 GB.

What do you think you can achieve with 4000 and co. if your CPU is only designed for up to 2666 Mhz? It won't be any more, you can put whatever you want into it.
it's quite unlikely. they are for desktop pc-s, they are quite big with heatsinks.
laptops need much smaller ram modules.
i think it should be possible to filter the results for laptop rams.
No, the only thing to do is to go into the bios to change the X.M.P profile, which is an overclock profile predefined by the distributor. There is no risk in the bios as long as you don't change the other parameters. There are plenty of tutorials on the internet that simply explain how to do this.
