DDR4 DIMMs and SODIMMs — for upgrading and maintaining the large installed base of DDR4-generation systems.
The DDR4 installed base is enormous — years of servers, desktops and laptops that a memory upgrade can extend well before a full refresh. Adding DDR4 to bring a fleet of existing machines up to a working memory floor is often the highest-return, lowest-disruption spend available. This slice locks the catalog to DDR4 modules.
Listings are live and priced. Filter to the exact module (capacity, form factor and — for servers — speed and rank) and send it as a quote to lock current pricing across the quantity.
A live, priced selection filtered to this specification — refine further on the rail. Every order is screened for TAA country of origin and NDAA §889 status before any payment.

Buyer's checklist
Choosing DDR4 memory
Confirm the platform takes DDR4 (not DDR5 or DDR3) — the standards are not interchangeable.
Match the form factor: DIMM for desktops and servers, SODIMM for laptops and small-form-factor.
For servers, verify ECC/registered support, speed and rank against the system's qualified list.
Match the new modules' speed and rank to the existing installed memory when adding to populated systems.
Choose capacity to reach the target total in the available slots.
Every line is screened for TAA country of origin and NDAA §889 status before it ships on a federal order.
FAQ
Common questions
Can I mix new DDR4 with the memory already installed?
Often yes, but match the speed, rank and (for servers) ECC/registered type of the existing modules, and populate channels sensibly — mismatched modules can run at the slowest common speed or fail to post. Send the system model with a quote and we'll match the module.
Is upgrading DDR4 worth it versus replacing the machine?
Frequently — adding memory to a capable DDR4-generation system to reach a working floor is a low-cost way to extend its service life and cut performance complaints ahead of a full refresh. Filter to the module you need and request a quote.
Everything here checks out on the hub — priced lines carry the live storefront price, and unpriced lines are added as request-pricing and confirmed by a sales engineer before any payment. Every order is TAA country-of-origin verified and NDAA §889 screened.
