DDR4-2666 CL19 8GB RAM prices

The cheapest listed kit costs $53.99 ($6.75 per GB). The median is $7.50 per GB, across 11 ranked Newegg listings.

Checked on Oct 31, 2026. US dollars; tax and shipping excluded.

What this list covers

127 listings of other kinds, such as server, laptop, OEM-replacement or used parts, 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.

Speed, CAS latency and total capacity come from the maker's specification where the kit is matched to it, otherwise from the listing's title, so a kit appears here only when all three are stated. A shared speed and latency does not establish fit: check the motherboard's memory support list.

How to read this list

Generation, speed, latency, socket, interface and form factor can be searched together. Specifications from a listing title are not a fit check. “New” means the listing is not labelled used or refurbished. “Like it” compares a product with the others of the same capacity, generation and condition on this page. “Lowest we have recorded” compares the latest price with every daily price we have recorded for that exact product.

Will DDR4-2666 run at 2666 in my PC?

2666 MT/s is within the rated speed of Ryzen 3000 (AM4), Ryzen 5000 (AM4), Core 12th Gen and Core 13th and 14th Gen.

Rated speeds with two modules: Ryzen 3000 (AM4) DDR4-3200 (2933 for the G models with graphics); Ryzen 5000 (AM4) DDR4-3200; Core 12th Gen DDR4-3200; Core 13th and 14th Gen DDR4-3200. Four modules are rated lower. The board decides the rest: check its memory support list, and read XMP and EXPO.
