Buy the capacity you need now, do not buy speculatively, and a working kit you are happy with is not a reason to buy. Part of this market's demand is fear of higher prices, and buying on fear is how a buyer ends up owning capacity they did not need at the top of a price cycle. If your machine works and the memory in it is enough for what you run, the right amount to buy today is none.
Sixty-four gigabytes of DDR5 laptop memory is sold as a pair of 32GB SO-DIMMs, and the population is small: the in-stock count is printed at the top of this page and every level here describes that handful of listings.
A pair fills two sockets, so this size is only relevant to a laptop with two usable DDR5 sockets and a documented maximum of at least 64GB. That narrows the audience sharply before price is considered at all.
On 2026-10-05 we hold 10 new, non-ECC DDR5 laptop SO-DIMM listings totalling 64GB from 5 brands (G.Skill, Crucial, ADATA, TeamGroup, Kingston). The module layouts on offer, with counts, are 2 x 32GB (9), 1 x 64GB (1). The stated rated speeds present at this size are DDR5-4800, DDR5-5600, 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 G.Skill Ripjaws 64GB (2x32GB) DDR5-4800 CL40 at $900, or $14.06 per gigabyte; the median across the size is $17.46 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 $7.86 per gigabyte, computed from 10 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.
All 10 in-stock listings, cheapest per gigabyte first. Every price divides by the TOTAL capacity. Speed and latency are the listing's stated specification.

Per gigabyte, at the cheapest kit for each size and on the date above: 32GB at $13.75 per gigabyte (64GB is +2.3% 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.
Sixty-four gigabytes in a laptop is workstation territory: large virtual machine labs, big in-memory datasets, heavy creative projects on the move. Most laptop owners will never use it.
If that is your work, check it against the published requirements on our sizing page, and against what your laptop is documented to support, before you price it.
Not every laptop is documented to 64GB, and capacity above the documented maximum is capacity the machine is not specified to use. The maker's specification page for your exact model is the authority, together with the socket count and any soldered memory.
A 64GB laptop kit is one of the larger memory purchases on this site. Nothing about the shortage makes it more urgent for a machine that does not need it; if yours does not, decline today's price.
As of 2026-10-05, the cheapest new 64GB DDR5 laptop kit we track is G.Skill Ripjaws 64GB (2x32GB) DDR5-4800 CL40 at $900, $14.06 per gigabyte, out of 10 in stock. That is a single listing, so it can change because one kit sells out; the median is $17.46 per gigabyte.
Only if it has two usable DDR5 SO-DIMM sockets and is documented to a 64GB maximum or more. The maker's specification page for your exact model states both.
It is a small segment in our listings. The number in stock is at the top of the page, and with so few the cheapest and median describe a handful of listings.
