Kingston FURY Beast RGB KF556C40BBAK2-16 Review
The Kingston FURY Beast RGB KF556C40BBAK2-16 is the entry-capacity kit in Kingston’s accessible 5600MHz RGB DDR5 tier, 16GB (2x8GB) with genuine RGB lighting at a price point.
Budget-conscious builds wanting an entry-level RGB DDR5 kit. Real lighting at the most accessible capacity point in Kingston’s RGB DDR5 lineup. Not for builds needing 32GB or more. Step up within the same FURY Beast RGB line for more capacity.
Performance and Timings
CL40 at 5600MHz gives roughly 14.3ns true latency, appropriate for entry-level DDR5 builds and secondary systems rather than the primary performance choice for a demanding build.
Compatibility
Intel XMP 3.0 certification reaches the rated 5600MHz. 8GB-per-module kits are among the most broadly validated DDR5 configurations across current motherboard QVLs.
Module Count and Rank
Two 8GB modules. Buy the capacity needed in one matched kit rather than combining separate kits later.
Design and Build
Dynamic RGB with Infrared Sync technology and FURY CTRL software, matching the design language of the rest of Kingston’s FURY Beast RGB line.
Overclocking and BIOS Setup
Boots at JEDEC baseline until XMP is enabled. Select the profile, choose 5600MHz CL40, save, reboot, verify in CPU-Z.
Comparison to Alternatives
Against Kingston’s own FURY Beast 16GB at 6000MHz CL36 (non-RGB), this kit trades tighter timing and platform-recommended AM5 frequency for RGB lighting at a comparable price tier.
