What is covered
Named DDR4 and DDR5 kits from Corsair, G.Skill, Kingston and TeamGroup, plus generic capacity buckets (any brand) for listings that don't name a kit.
The bar on each row runs from the lowest to the highest sale counted (the figures at its ends), with the middle half shaded and the median as a dot. Each bar is scaled to its own part’s sales. How prices are worked out
