How to read this

  • "Typically" is the median Buy It Now price per GB now - half the listings cost less - the same figure as the home page; "from" is the cheapest.
  • The lines and every change use a like-for-like price. Listings are sorted into fixed kinds (generation, kind of module, condition, size and pack), each kind is priced by the middle half of its listings, and the kinds are weighted by the last week's counts, set afresh each UTC day. Because it prices the same kinds every time, a batch of cheap or dear listings arriving or leaving moves it far less than the median; prices moving within the kinds move it fully. When a batch still steps it, the step is marked and is not counted as a price move. Up is dearer and down is cheaper, shown by the arrow and the sign as well as the colour.
  • Each chart has one no-change zone, a faint band between two fine lines: how far the line can wander from measurement noise alone. A change inside it reads "no clear change"; beyond it, "a real rise" or "a real fall". On the 4- and 12-hour windows it comes from how precisely each reading is measured for the first week, which can make it narrow, and after that from how far the line has moved over the same span in the past week. From 3 days it is set wide on purpose for the first four weeks, then narrowed from a month of daily prices.
  • The dashed line is the cheaper end, the same kinds priced by the cheaper part of their listings. It is shown for comparison and gets no verdict.
  • A hollow point had fewer comparable listings than usual; a gap had too few to draw, and is never bridged. ◆ marks where our catalogue refreshed a batch of listings: that step is our harvest, not prices.
  • Asking prices hardly move within hours. Read any point of a chart - the last day, the high, the low - by pointing at it, dragging a finger along it or with the arrow keys. From 15 days of readings the 7-, 15- and 30-day charts add how much the price typically moves a day, measured on daily closing prices with the bounce-back that is noise taken out. Every time on the page is UTC.
  • All RAM is every kind together, weighted by the last week's counts, so a shift in the mix moves it far less than the median; under "Which moved most" it is drawn apart, below the others.
  • By module size: each dot is the typical price per GB now of a single module of that size - kits are left out - in order, on a log scale. Sizes with plenty of varied listings get a trend every 15 minutes, thinner ones in 6-hour steps, and the rest show their price only (grey). The best size is the cheapest with enough comparable listings and changes only after a rival stays clearly cheaper for 2 hours; it is flagged when its listings are mostly server modules (RDIMM/LRDIMM), which need a server board. Every size with a price is listed.
