Viper Venom RGB is Patriot's illuminated DDR4 kit, sold in this family at one speed grade across both capacities. The lighting is the main thing separating it from Patriot's plainer Viper lines, rather than anything in the timings.
This kit is 2×16GB, 32GB total, at 3200 MT/s CL16. Since 3200 MT/s and CL16 hold steady across the family, the two listings are distinguished only by 32GB — worth checking against how many DIMM slots a board actually has free before choosing the larger kit.
This is UDIMM DDR4 for desktop boards with RGB software support; the motherboard's own utility drives the lighting, and reaching 3200 MT/s still requires the XMP profile to be enabled rather than the module's default clock.
