About RAMindex

In short: RAMindex ranks computer memory listed on eBay by price per gigabyte, cheapest first. One person runs it, and affiliate commission from eBay pays for it without ever changing the order.

Who runs it

RAMindex is written and run by one person based in Portugal. There is no company and no team behind it, which is worth knowing when you weigh what you read here.

What it does that eBay search does not

eBay's search matches the words in a listing title. It cannot tell that a "16GB (2x8GB) DDR4 3200" kit is two 8GB modules making 16 gigabytes in total, and it cannot sort by the measure memory is actually sold by: price per gigabyte.

RAMindex breaks every listing title down into separate fields - capacity, module count, speed, form factor, ECC, buffering, rank count and part number - so you can filter and sort by them.

That breakdown is the product, and it does not guess. When a title does not state something, the field is left empty. When a listing's total capacity or shipping cost cannot be established, it gets no price per gigabyte at all: an empty cell is honest in a way a confident wrong number is not.

No language model is used anywhere in turning a listing into a table row. It is done with rules and tests, because a parser that is occasionally creative about a capacity is worse than no parser.

Prices come straight from eBay

Prices are collected through eBay's official Browse API under an API licence, never scraped, and refreshed continuously through the day. What you see is a snapshot that can be a few hours old, and every page says how old. The live price is always the one on eBay.

Commission pays for it, and never sets the order

Links to eBay are affiliate links: if you buy something after following one, RAMindex may earn a commission from eBay at no extra cost to you. That is its only income. There is no advertising, nothing is sponsored, no seller pays to appear or to rank higher, and no listing is moved up or down by hand.

The ranking is arithmetic: price plus shipping, divided by total gigabytes, cheapest first, as the methodology page explains. The commission is the same whatever the order, so there is nothing to gain from ranking listings any other way. If that ever stops being true, this paragraph is where it will be corrected.

Treat the figures as a starting point

Availability changes faster than any comparison site can follow, so treat a listing here as a pointer to eBay rather than as a quote.

Compatibility data - which memory a given server takes - is a separate dataset. It is researched from vendor documentation rather than from listings, and it covers servers only. Where vendor documents disagree with each other, the disagreement is reported rather than settled by picking one. Check the listing and your own hardware before you buy.
