Choosing RAM comes down to three things: how much you actually need for your use case, whether your motherboard supports DDR4 or DDR5, and whether you want to squeeze out the latest generation. Here are eight modules currently available on Amazon.es, from most affordable to most premium.

How much RAM do I need?

16GB is plenty for browsing, office work, and playing the vast majority of current games without issue. If you also edit video, run virtual machines, or want headroom for the next few years, 32GB is the more sensible choice. Below 16GB today you can fall short even for everyday tasks, so it’s rarely worth going lower.

DDR4 or DDR5

The memory generation you can use depends on your motherboard — it’s not a free choice, since each board only accepts one type. DDR4 remains a solid, cheaper option for already-built or mid-range systems, while DDR5 is mandatory on the newest boards and offers more bandwidth, though it still costs noticeably more per module today.

One module or a two-module kit

Whenever your motherboard allows it, buying RAM as two modules instead of one (say, 2×8GB instead of 1×16GB) usually gives a bit more performance thanks to dual-channel mode, especially noticeable with a powerful graphics card. The difference isn’t huge, but since it’s usually the same price, it’s the sensible default choice.
