How we rank
DDR5 kits only, for boards that take DDR5. Most capacity first, then the faster speed, then the lower CAS latency, then the cheaper kit.
Only DDR5 RAM kits with a photo, a full spec table and a new, in-stock price read in the last two weeks are considered, so a part that is sold out everywhere drops off until a shop has it again. Refurbished and used stock is left out. Prices change through the day: check the shop before you buy. We may earn commission when you buy through a link on a product page; it never changes the order here.
