DDR5 in 2026: what actually matters when you buy
Speed, CAS latency, EXPO vs XMP, 2×16 vs 2×24, and why the sticker price is the least interesting number on the listing.
Updated 2 July 2026 · RAMPrice editorial — no paid placement, see methodology.
DDR5 pricing is volatile enough that the same kit can swing 20% inside a month, and the spread between marketplaces is often bigger than the spread between brands. Before you chase a deal, get the spec right — then let the market come to you.
The three numbers that matter
Capacity first: 32 GB (2×16) is the sensible default for gaming and general work in 2026; 64 GB (2×32) if you compile, run VMs, or edit video; 48 GB (2×24) is the value sweet spot on Intel boards that price 24 Gb-die kits close to 32 GB ones.
Speed and latency together, not separately. A useful shorthand is the ratio of speed to CAS: DDR5-6000 CL30 (ratio 200) beats DDR5-6400 CL38 (ratio ~168) for most real workloads. For AMD AM5, DDR5-6000 is still the 1:1 sweet spot for the memory controller; paying a premium for 7200+ only pays off on Intel with a specific use case.
Kit configuration: two sticks, not four, unless you know why you need four. Four single-rank sticks stress the memory controller and often force a speed downgrade. That 2×16 kit is not "the same" as a 4×8 kit at the same price.
EXPO, XMP, and why the profile name matters less than you think
EXPO is AMD’s profile standard, XMP is Intel’s. Most current kits ship both or work fine with the “wrong” one, but if you want the advertised numbers to apply at the press of one BIOS toggle, buy the profile that matches your platform. Our filters carry the marketing speed (MT/s) and CAS from the listing, so compare like with like.
Why we rank by landed price
The same Corsair or G.Skill kit is stocked by five-plus Amazon marketplaces at meaningfully different prices. A Berlin buyer can regularly save by buying the US or Spanish listing — but only after conversion, shipping and import VAT are counted honestly. That final number is what we sort by; click any price on the comparison to see its full breakdown, and set an alert at the per-GB price you want to pay.
Quick sanity checklist
- Two sticks over four; match EXPO/XMP to your platform.
- DDR5-6000 CL30 is the AM5 default answer; buy capacity before speed.
- Compare per-GB landed price, not sticker — the table has a column for it.
- Heat spreaders and RGB add price, not performance; filter RGB off if you don’t care.
