I don't grasp the distinctions between various RAM modules in those models. They all share the same voltage, timing, and dimensions, though the retail prices differ slightly.
4-3600C18D-16GTZRX and 4-3600C18D-16GTZN are the same model. The RX claims compatibility with AMD platforms, whereas the N states full support on the newest AMD Ryzen 3000 series processors with AMD X570 chipsets. It seems the RX might not have been tested for Zen 2, though it likely functions, while the N is a bit more recent.
The variation lies in the actual DRAM modules inside. One employs Samsung B-Die, while the other switches to SK Hynix A-Die. This second model also meets AMD Ready validation, unlike the first which uses Samsung B-Die.
