16GB DDR5 Laptop RAM: Live SO-DIMM Prices

16GB DDR5: what you are buying

Sixteen gigabytes of DDR5 laptop memory is listed as a single 16GB SO-DIMM or as two 8GB modules. Each listing is priced here per gigabyte of the total, with the module count alongside.

A single module adds to or replaces one socket; a pair replaces whatever both sockets hold. The machine decides which is relevant: count its sockets and what is already in them.

DDR5 SO-DIMM is the memory of the newer laptops that still have sockets at all, and it is worth saying plainly that many recent thin laptops have none, with every gigabyte soldered at the factory. The /ram/laptop page explains why we do not keep a list of which ones; the maker's specification page for your model does.

What is in stock at 16GB DDR5 today

On 2026-10-05 we hold 20 new, non-ECC DDR5 laptop SO-DIMM listings totalling 16GB from 6 brands (TeamGroup, ADATA, Samsung, G.Skill, Lexar, Kingston). The module layouts on offer, with counts, are 1 x 16GB (15), 2 x 8GB (5). The stated rated speeds present at this size are DDR5-4800, DDR5-5600, DDR5-6400, printed as the listings give them: they are the makers' specifications and we neither rank kits by them nor call any of them worth a premium.

The cheapest is TeamGroup 16GB DDR5-5600 CL46 at $230, or $14.37 per gigabyte; the median across the size is $16.87 per gigabyte. The gap between them is worth as much as either number: a floor far below the median means the cheap end is one or two kits deep, and a floor close to it means the size is priced tightly together. The plausibility floor for this exact size is $7.59 per gigabyte, computed from 20 established-brand listings; a kit priced under it is priced where a counterfeit would be, and is a reason to check the seller, not a verdict.

How 16GB prices against the neighbouring sizes

Per gigabyte, at the cheapest kit for each size and on the date above: 32GB at $13.75 per gigabyte (16GB is +4.5% against it). That is a levels comparison of single cheapest kits, so it can change because one kit sells out or appears, with no seller changing a price. It tells you where the cheapest gigabyte is today, which is useful for deciding what to buy today; it does not tell you that prices moved.

The per-gigabyte view is worth having and it is also the reason for caution. A larger kit that costs less per gigabyte is still a larger purchase, and the cheapest gigabyte you do not need is the most expensive one you can buy. The next section is about that.

Who needs 16GB, and who does not

Sixteen gigabytes suits the everyday laptop: browsing, documents, calls, light editing. For a DDR5 laptop that came with 8GB and runs short of memory, it is the obvious step.

Whether 16GB is enough depends on what you run, not on the generation. The sizing page works through it from the software makers' own published requirements.

Check your platform first

Confirm that your laptop has a free or replaceable DDR5 SO-DIMM socket before buying. The maker's specification page states the memory type, socket count, soldered memory and maximum for your exact model; DDR4 modules will not seat in a DDR5 socket or the reverse.

Do not buy 16GB on panic

If your laptop already has 16GB and works, there is nothing to buy here. If it has 8GB and memory is what is running out, buy the 16GB it needs and stop.
