Kacbu lists 3 Memory (RAM) DDR5: Corsair, G.Skill, Kingston. The family is assembled by hand from what each maker calls its panel; the values it includes are listed below one by one, each with its own page.
The maker's own name is kept as written; every value has its own page.
DDR5 is the socketed memory standard of desktops and laptops; over DDR4 it brings higher data rates and two sub-channels per module. In a laptop DDR5 usually means SO-DIMM slots, so the memory can be added to later; look at where the maker states the slot count and the maximum. For a processor or a motherboard DDR5 describes the supported type, not what is in the box.
