Overview
The Kingston FURY Beast White RGB KF556C40BWAK4-128 is a 128GB DDR5 desktop memory kit designed for compatible systems requiring substantial memory capacity and configurable performance. It comprises four 32GB memory modules featuring white heat spreaders and RGB lighting.
Part of the Kingston FURY Beast White RGB series, this kit combines DDR5 memory technology with Intel Extreme Memory Profiles (XMP) 3.0 support. Its four-module configuration is intended for compatible desktop motherboards with sufficient memory capacity and four supported DIMM slots.
Memory Performance and Technical Information
The kit supports a rated data transfer rate of 5600MT/s with primary timings of 40-40-40 at 1.25V using its primary XMP profile. Its programmed default JEDEC profile operates at DDR5-4800 with timings of 40-39-39 at 1.1V.
Additional programmed profiles include DDR5-5200 at 40-40-40 and 1.25V, and DDR5-4800 at 38-38-38 and 1.1V. Actual operating performance depends on the supported memory profiles and configuration of the installed processor and motherboard.
Compatibility and Installation
This kit uses standard 288-pin DDR5 unbuffered DIMMs. The motherboard and processor must support DDR5 memory, the total 128GB capacity, and the intended four-module configuration.
Intel XMP 3.0 profiles require a compatible platform and may need to be enabled in the system firmware. The maximum achievable memory speed can vary with processor specifications, motherboard firmware, and the number of populated memory slots.
The modules are non-ECC system memory with on-die ECC incorporated into the DDR5 memory chips. On-die ECC does not provide the same functionality as system-level ECC memory.
RGB Lighting and Physical Design
The FURY Beast White RGB design features white heat spreaders and integrated RGB lighting. The module height is approximately 42.23mm, including the heat spreader. Check motherboard and CPU cooler clearance before installation, particularly in compact desktop builds.
Key Features
- 128GB total capacity: Four matched 32GB DDR5 memory modules.
- DDR5-5600 performance: Rated 5600MT/s data transfer rate with CL40-40-40 timings at 1.25V using the primary XMP profile.
- Intel XMP 3.0: Supports configurable memory profiles on compatible systems.
- White RGB design: White heat spreaders with integrated RGB lighting.
- 288-pin DIMM format: Unbuffered desktop DDR5 memory modules.
Applications
- Compatible desktop computers requiring 128GB of DDR5 memory.
- Workstations running memory-intensive professional applications.
- High-capacity desktop configurations involving large datasets and demanding multitasking workloads.
- Custom desktop builds incorporating white components and RGB lighting.
DC Supplies Product Note
Confirm support for four 32GB DDR5 modules before purchasing. Some processors and motherboards reduce supported memory speeds when all four slots are populated, so the rated 5600MT/s profile may not be achievable in every system. Kingston also specifies that the modules in this kit should not be sold or used separately if the kit warranty and return conditions are to remain valid.

Frequently Asked Questions
Is KF556C40BWAK4-128 a single 128GB memory module?
No. This product is a kit containing four 32GB DDR5 memory modules, providing 128GB of total memory capacity.
Will this kit operate at 5600MT/s on every DDR5 motherboard?
No. The motherboard and processor must support the memory configuration and desired speed. The primary 5600MT/s profile uses Intel XMP 3.0, and the achievable operating speed depends on platform capabilities and configuration.
Does this memory kit include RGB lighting?
Yes. The FURY Beast White RGB model features integrated RGB lighting and white heat spreaders.
Can the four modules be used individually?
Kingston specifies that the kit warranty is void and returns are not accepted if the kit is sold or used separately. Keep the modules together as a kit and follow the manufacturer's installation guidance.
Is this an ECC server memory kit?
No. This is non-ECC, unbuffered desktop memory. Its on-die ECC feature does not replace system-level ECC support required by certain servers and workstations.
