Product overview

Crucial’s CT2K8G4DFRA266 is a 16GB (2×8GB) DDR4‑2666 non‑ECC UDIMM kit from the brand’s standard desktop DDR4 line. It was on retail shelves by July 27, 2021, and runs at JEDEC‑standard 2666 MT/s, 1.2 V, 288‑pin for broad platform compatibility.

Positioned as a budget‑tier kit, it exists to provide an inexpensive, drop‑in dual‑channel upgrade for DDR4 systems where stability and compatibility matter more than peak speeds or tuning. The 16GB capacity suits everyday use, office work, light content creation, and entry‑level gaming; the plain, heatsink‑free PCB aids cooler clearance and OEM/prebuilt compatibility.
