128GB DDR5 RAM prices

The lowest listed unit price is $15.23 per GB. The median is $20.60 per GB, across 76 ranked Newegg listings. 27 server, laptop, OEM-replacement or used listings are left out of these figures.

Prices and value ranks here cover new desktop DDR4 and DDR5 modules. Laptop, server and ECC and used memory have their own pages. A shared generation or capacity does not establish fit.

Updated Sep 28, 2026. US dollars; tax and shipping excluded.

Compare the total kit capacity and the number of modules. A kit's total capacity is different from each module's capacity; the listing and manufacturer-specification labels below keep them separate.

14 ranked products from 76 listings (the same maker, size and price listed more than once is shown once) · Newegg US · Updated (7 hours ago).

Listings are on Newegg; the marketplace seller is not supplied. Prices exclude tax and shipping. Availability can change at checkout. Newegg links are affiliate links; a purchase may earn a commission. Affiliate status does not affect order.

Filter by model, manufacturer, condition or specification

The platform control narrows RAM by generation and CPUs or boards by stated socket. Check the exact board's module type and support list; this is not a complete fit verdict.

Generation, speed, latency, socket, interface and form factor can be searched together. Listing-title specifications are labelled on each row; they do not establish fit. “New” means the listing is not labelled used or refurbished. A missing warranty is unknown.
