Kingston FURY Beast RGB DDR5-5200 CL40 32GB Kit (2x16GB) Desktop Memory, Intel XMP 3.0, Black

The Kingston FURY Beast RGB KF552C40BBAK2-32 is a two-module 32GB kit (2 x 16GB) of DDR5 desktop memory rated at 5200 MT/s with CL40-40-40 timings at 1.25V, aimed at gamers and builders upgrading an Intel DDR5 desktop.

Out of the box it boots at the default 4800 CL40-39-39 at 1.1V; the rated 5200 MT/s speed is applied by enabling the Intel XMP 3.0 profile in the BIOS. The black heat spreader carries an RGB light bar controlled through Kingston FURY CTRL software or compatible motherboard RGB software.

DDR5 at 5200 MT/s gives noticeably more bandwidth than DDR4, which helps in CPU-bound games, content creation and heavy multitasking; lower CAS latency (CL40) shortens the time the CPU waits for data. As a matched kit, the two modules are tested together at the rated profile.

• 2 x 16GB Kingston FURY Beast RGB DDR5 modules (black), tested together as a matched kit
• Manufacturer retail packaging
• No screws, cables or drivers needed — memory installs straight into the DIMM slots; the RGB control software (Kingston FURY CTRL) is a free download

• First boot runs at 4800 CL40-39-39 at 1.1V. Enable Intel XMP 3.0 in the BIOS to get 5200 MT/s — skipping this step is the most common reason new memory “feels slow”.
• Two 16GB modules fill two slots for dual-channel operation. On a four-slot board use the slots your motherboard manual marks for two-DIMM operation (usually A2 and B2).
• Module height is 42.23 mm including the heat spreader — check clearance under large air coolers whose front fan overhangs the memory slots.
• Adding more modules later is possible on four-slot boards, but four DDR5 modules usually run at lower speeds than two; if you need more than 32GB, buying the full capacity as one kit is the safer route.
• Update the motherboard BIOS before fitting new DDR5. The first boot after installing memory can take noticeably longer while the board trains the memory — this is normal, not a fault.
• 32GB is a comfortable amount for current games, streaming alongside gaming, photo editing and everyday multitasking; video editing, large datasets or virtual machines benefit from 64GB or more.
• If the rated profile is not stable on your system, the second profile (4800 CL38-38-38 at 1.1V) gives you a tested fallback without manual tuning.

• DDR4 motherboards — DDR5 modules are keyed differently and will not physically fit.
• Laptops, mini PCs and all-in-ones that use SO-DIMM or soldered memory — this is a full-size 288-pin desktop module.
• Servers and workstations that require registered (RDIMM) or ECC memory — this is non-ECC unbuffered memory (on-die ECC only).
• One-click rated speed on AMD AM5 boards — there is no AMD EXPO profile; on AMD it runs at the default 4800 CL40-39-39 at 1.1V unless the board can read XMP or you enter the values manually.
• Guaranteed rated speed with four modules installed — the rated profile is validated for the modules as supplied in the kit, not for mixed or four-module setups.
