The Kingston FURY Beast KF556C40BB-8 is an 8GB DDR5 desktop memory module designed for compatible systems using DDR5 DIMM memory. It operates at a rated data transfer speed of 5600MT/s with tested timings of CL40-40-40 at 1.25V, providing a memory upgrade option for desktop computers used for everyday computing, productivity and gaming.
Featuring a black heat spreader, a 288-pin DIMM form factor and support for Intel XMP 3.0, the Kingston FURY Beast combines a distinctive design with configurable memory performance. Its single-module 8GB capacity makes it suitable for compatible systems where an individual DDR5 memory module is required.
Key Features
- 8GB DDR5 capacity: A single 8GB memory module for compatible desktop computers.
- 5600MT/s data transfer speed: Tested at 5600MT/s with CL40-40-40 timings and 1.25V operating voltage.
- Intel XMP 3.0 support: Provides predefined memory profiles for compatible systems.
- Black heat spreader: A low-profile design that complements a range of desktop PC builds.
- On-die ECC: DDR5 memory-chip error correction technology designed to help improve internal memory reliability.
DDR5 Memory for Everyday Computing
DDR5 is a newer generation of system memory designed for compatible desktop platforms. This 8GB Kingston FURY Beast module can support everyday applications, general multitasking and other workloads according to the memory capacity and configuration of the complete system.
System performance depends on the processor, motherboard, operating system, applications and memory configuration. For workloads that require greater memory capacity, check the motherboard's supported configurations and available memory slots before choosing an upgrade.
Intel XMP 3.0 Support
The KF556C40BB-8 supports Intel Extreme Memory Profile (XMP) 3.0. On compatible systems, an XMP profile can be selected in the motherboard BIOS to apply predefined memory settings.
The module is tested for DDR5-5600 operation at CL40-40-40 and 1.25V. Its default JEDEC profile operates at DDR5-4800 CL40-39-39 at 1.1V. Actual operating speed depends on motherboard and processor support, BIOS configuration and the installed memory configuration.
Black Heat Spreader Design
The Kingston FURY Beast features a black heat spreader with a low-profile design. At approximately 34.9mm tall, including the heat spreader, it can suit a variety of desktop builds. Check the available clearance in your computer case and around the CPU cooler before installation.

Compatibility and Installation Notes
This memory module is designed for desktop motherboards with compatible DDR5 DIMM slots. It is not compatible with DDR4-only motherboards or laptop memory slots that require SO-DIMM modules.
Before purchasing, check your motherboard's memory specifications, supported capacities and compatibility list. The rated DDR5-5600 speed may require enabling the appropriate XMP profile in the BIOS. The final operating speed depends on the system configuration.
On-die ECC is built into DDR5 memory chips and is not equivalent to full system-level ECC support. This module is specified as non-ECC, unbuffered desktop memory.
