Mobo compatibility lists are bs. Any ram works with any mobo. At best the list is just the kits they bothered to verify that are built and performs well, at worst it’s just advertisement for the ram company.

RS is ripjaws (low profile xmp), FX is flare x (low profile expo), TZ is Trident Z (high profile). 5 is the ddr version. In Trident Z models N suffix indicates expo, others are xmp. R is for rgb and other letters are colors (w - white, s -silver, k - black).

Expo is for amd xmp is for Intel, though almost all amd boards recognize xmp and some Intel boards recognize expo too. Everything else equal, expo should be marginally faster.
