Product overview

Crucial’s 16GB DDR5‑4800 UDIMM (CT16G48C40U5) arrived on October 27, 2021 as part of the brand’s first‑wave DDR5 desktop memory. It’s a 288‑pin, JEDEC‑spec 4800 MT/s CL40 module, and this SKU supports both Intel XMP 3.0 and AMD EXPO profiles for straightforward setup.

Positioned in the budget tier, it exists to give builders a stable, widely compatible entry to DDR5 at stock speeds. The 1×16GB layout fits budget builds and entry‑level gaming, and pairs well with Intel Core (XMP) and AMD Ryzen 7000 (EXPO) platforms; add a second identical stick to enable dual‑channel. Micron ended Crucial consumer shipments in February 2026, so this module is effectively discontinued and found mainly via remaining channel inventory.
