Kingston FURY Beast 64GB (2x32GB) DDR5 5200MT/s CL40 Kit of 2 - KF552C40BBK2-64
Kingston FURY Beast DDR5 in a 64GB kit made up of two 32GB modules — part KF552C40BBK2-64. It runs at 5200MT/s with CL40 timings on its XMP profile, in a low-profile black heat spreader that clears most large air coolers. Two modules rather than four means it suits a standard dual-channel board and leaves two slots free.
Why this product
64GB as two 32GB modules
A kit of two, so it fills the two primary slots on a standard board and leaves the other two empty for a later upgrade. Kingston's part suffix BBK2 marks the two-module kit; BBK4 is the four-module version of the same capacity.
5200MT/s at CL40 on XMP
The XMP profile runs 5200MT/s with 40-40-40 timings at 1.25V. Without XMP enabled the modules default to the JEDEC SPD setting of DDR5-4800 at 40-39-39 and 1.1V.
Low-profile black heat spreader
The FURY Beast DDR5 heat spreader is a low-profile design in black, which keeps clearance under large tower air coolers where taller modules foul the fan.
DDR5 architecture
On-die ECC, dual 32-bit subchannels per module and an on-module power management IC — the DDR5 features that improve signal integrity and power delivery over DDR4.
Plug-and-play XMP
Intel XMP 3.0 certified. Enable the profile in the BIOS and the kit configures itself to 5200MT/s rather than needing manual timings.

- 288-pin non-ECC unbuffered DIMM (UDIMM) — the standard desktop DDR5 form factor.
- Two modules, so it populates a dual-channel board's two primary slots and leaves two free.
- Intel XMP 3.0 certified. Enabling XMP in the BIOS sets 5200MT/s, 40-40-40, 1.25V.
- Without XMP enabled the kit runs at its JEDEC SPD default of DDR5-4800, 40-39-39, 1.1V. That is normal — the rated speed needs the profile turned on.
- Kingston states that a kit's warranty is void, and returns are not accepted, if the modules are sold or used separately. Keep the pair together.
- This is the two-module kit, KF552C40BBK2-64. Kingston also sells 64GB as four 16GB modules under KF552C40BBK4-64 — a different part.
Best for
- Dual-channel desktop boards with four slots, where two modules now leaves room to add more later.
- Builds with a large tower air cooler, thanks to the low-profile heat spreader.
- Anyone who wants rated speed without manual tuning — one XMP toggle and it is done.
- Workstation and content-creation machines where 64GB is the working requirement.
Trade-offs
- Boards that want four matched modules: this is a kit of two. The four-module 64GB kit is KF552C40BBK4-64.
- Anyone expecting 5200MT/s out of the box: that is the XMP figure. Left alone, the kit runs at the JEDEC default of 4800MT/s.
- RGB builds: this is the plain FURY Beast heat spreader, not the RGB version.
- Servers needing registered or ECC memory: these are non-ECC unbuffered DIMMs with on-die ECC only, which is not the same as module-level ECC.
- Splitting between two machines: Kingston voids the kit warranty if the modules are used separately.
Kingston FURY Beast DDR5, 64GB supplied as two 32GB modules — part KF552C40BBK2-64.
The module count matters as much as the capacity. Two modules fill the primary pair of slots on a standard dual-channel board and leave the other two empty, so there is headroom to add more later. Kingston's own part suffix is the tell: BBK2 is this two-module kit, BBK4 is the same 64GB split across four 16GB modules.
On its XMP profile the kit runs at 5200MT/s with 40-40-40 timings at 1.25V. It is Intel XMP 3.0 certified, so enabling the profile in the BIOS is all that is needed. Left alone it falls back to the JEDEC SPD default of DDR5-4800 at 40-39-39 and 1.1V — worth knowing if the advertised speed does not appear on first boot.
These are 288-pin non-ECC unbuffered DIMMs, 2Rx8, built on 16Gbit DRAM, with the DDR5 architecture's on-die ECC, dual 32-bit subchannels per module and on-module power management. The black heat spreader is a low-profile design, which keeps clearance under large tower air coolers where taller modules catch the fan.
Kingston covers FURY memory with a limited lifetime warranty. Note that the warranty applies to the kit as a pair: Kingston voids it, and will not accept returns, if the modules are sold or used separately.
