The Kingston FURY Impact is a single DDR5-5600 SODIMM for laptops and small-form-factor PCs that take full-size SO-DIMM slots. It runs at 5600 MT/s with a CAS latency of 40 and carries on-module ECC, so it can correct single-bit errors on supported platforms. It is a plug-and-play upgrade: no heatsink and no tuning needed, and it falls back to the platform's base speed if the laptop can't hold 5600. Against slower DDR5-4800 modules it gives more bandwidth for integrated graphics and memory-hungry apps; against DDR4 SO-DIMMs it is a different slot and won't fit older laptops.

Owners of DDR5 laptops and mini PCs report the module installs easily and runs at its rated speed on compatible machines. Most praise the stability and the value of a straightforward capacity boost; complaints center on laptops that downclock it and on buying one stick instead of a matched pair.
It runs at 5,600 MHz and uses unbuffered signal processing. It is sold as a single module.
