Product overview Kingston introduced the FURY Impact DDR5 SODIMM family on March 1, 2022; this KF556S40IBK2-32 variant is a 32GB kit (2×16GB) of DDR5‑5600 CL40 262‑pin SODIMMs aimed at notebooks and small‑form‑factor PCs. It runs a 1.1V Plug N Play default and carries Intel XMP 3.0 certification, with typical SODIMM height (~30 mm).
Position: mainstream. It exists to provide an easy dual‑channel 32GB upgrade that reaches the common DDR5‑5600 tier without extra voltage or tuning. Good for gaming and content‑creation laptops or mini‑PCs that benefit from 32GB capacity and higher DDR5 speeds; final operating speed depends on the system BIOS. Not discontinued.
Notable: combines Plug N Play auto‑overclocking with XMP 3.0 on a SODIMM kit.
