Kingston KF556C40BB-16

Kingston’s FURY Beast DDR5 family launched on October 27, 2021; the 5600 MT/s variants, including this 16GB single module (KF556C40BB-16), were available by March 27, 2022 as the lineup expanded. ([kingston.com](https://www.kingston.com/en/company/press/article/64844))

Positioned as a mainstream DDR5 option, it exists to offer an easy XMP 3.0 bump over JEDEC speeds without the cost or height of RGB modules. The module is a 1x16GB, 1Rx8, 288‑pin UDIMM rated for 5600 MT/s at CL40‑40‑40, 1.25V. ([kingston.com](https://www.kingston.com/en/memory/search?partid=KF556C40BB-16))

It’s a good pick for Intel XMP builds focused on gaming and general content creation, and as a single stick it suits budget builds with a simple path to 32GB by adding a second matching DIMM. A low‑profile heat spreader (about 34.9 mm tall) aids large‑air‑cooler clearance. Not discontinued as of 2026. ([kingston.com](https://www.kingston.com/en/company/press/article/64844))
