Kingston FURY Beast RGB KF556C40BBAK2-64 (64GB 2x32GB Kit/DDR5 5600MHz/CL40/RGB/Intel XMP 3.0) Review
The Kingston FURY Beast RGB KF556C40BBAK2-64 brings 64GB of high-density DDR5 capacity to Kingston’s accessible 5600MHz CL40 tier, appropriate for content creators and heavy multitaskers who want substantial RAM without paying for a higher frequency tier they don’t specifically need.
Content creators and heavy multitaskers wanting accessible 64GB RGB DDR5. Real capacity without paying for maximum frequency. Not for buyers wanting the tightest available 64GB timing. Kingston’s own 6000MHz CL30 64GB kit, covered elsewhere on this site, is the stronger performance choice.
Performance and Timings
CL40 at 5600MHz gives roughly 14.3ns true latency at 32GB-per-module density, a real capacity-focused kit rather than a latency-chasing one.
Compatibility
Intel XMP 3.0 certification reaches the rated 5600MHz. As a 32GB-per-module 64GB kit, confirm the board’s QVL supports this density specifically.
Module Count and Rank
Two 32GB modules, kept to two DIMMs for easier stability than a four-module configuration.
Design and Build
Dynamic RGB with Infrared Sync technology and FURY CTRL software, matching Kingston’s broader FURY Beast RGB design language at this higher capacity.
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 Sibling Products
Against Kingston’s own FURY Beast RGB 64GB at 6000MHz CL30, that kit delivers meaningfully better latency and bandwidth for a real price premium. This kit is the accessible route to 64GB with RGB for buyers not chasing maximum performance.
