Overview
The Kingston FURY Renegade Pro KF556R28RBE2K4-128 is a 128GB DDR5 ECC Registered DIMM memory kit designed for compatible high-performance desktop workstations and systems supporting registered DDR5 memory. It consists of four 32GB modules operating at a rated data transfer rate of 5600MT/s.
Designed for memory-intensive computing platforms, this kit combines registered memory architecture, error-correction capabilities, and configurable performance profiles. Its black finish and 288-pin DIMM form factor identify it as a Kingston FURY Renegade Pro memory product.
Memory Performance and Architecture
The kit supports a DDR5-5600 performance profile with timings of 28-34-34 at 1.35V. Its default JEDEC profile operates at DDR5-4800 with timings of 40-39-39 at 1.1V. Additional programmed profiles support DDR5-5200 operation.
Each 32GB module uses a dual-rank x8 organization and registered memory architecture. Registered DIMMs use a register to manage command and address signals, making them suitable for platforms specifically designed to support registered server or workstation memory.
ECC and Data Integrity
This kit supports ECC registered memory functionality and incorporates on-die ECC as part of its DDR5 memory technology. On-die ECC and system-level ECC serve different purposes; the module's system-level error-correction capabilities depend on a compatible processor and motherboard platform.
The registered design and ECC functionality make platform compatibility especially important when selecting this kit for professional computing systems.
Memory Profiles and Compatibility
The modules support AMD EXPO 1.1 and Intel Extreme Memory Profiles (XMP) 3.0. These profiles allow compatible systems to configure supported memory performance settings through firmware.
The rated 5600MT/s speed is profile-dependent and is not guaranteed on every compatible platform. Processor memory-controller limitations, motherboard specifications, firmware, and the use of four populated memory slots can affect the achievable operating speed.
This is registered ECC memory, not standard unbuffered desktop RAM. Confirm that the intended system explicitly supports DDR5 registered DIMMs before purchasing. Physical slot compatibility alone does not establish electrical or platform compatibility.
Key Features
- 128GB memory capacity: Four 32GB modules supplied as a matched kit.
- DDR5-5600 performance profile: Supports 5600MT/s with 28-34-34 timings at 1.35V.
- ECC registered architecture: Designed for compatible platforms supporting registered DDR5 memory with ECC.
- AMD EXPO and Intel XMP 3.0: Provides configurable memory profiles for supported systems.
- Dual-rank module design: Each 32GB DIMM uses a 2Rx8 organization.
Applications
- Compatible workstations requiring high-capacity registered DDR5 memory.
- Professional computing systems designed for ECC registered DIMMs.
- Memory-intensive workloads that benefit from a 128GB total memory configuration.
- Supported platforms requiring four 32GB DDR5 registered memory modules.
DC Supplies Product Note
Before ordering, verify registered DDR5 DIMM support in the exact motherboard and processor documentation. This is a critical distinction from unbuffered DDR5 memory: a system that accepts DDR5 UDIMMs does not necessarily support RDIMMs. Also confirm whether the intended platform supports 128GB across four modules at the desired data rate.

Frequently Asked Questions
Is this memory compatible with standard gaming desktop motherboards?
Not necessarily. This kit uses registered DDR5 DIMMs. Many consumer desktop motherboards support unbuffered memory only, so the motherboard and processor documentation must explicitly confirm RDIMM compatibility.
Does this kit provide ECC memory functionality?
Yes. It is an ECC registered memory kit. Actual system-level ECC operation depends on compatible processor and motherboard support and the system's configuration.
Will the memory operate at 5600MT/s automatically?
Not in every system. The default JEDEC profile is DDR5-4800. The DDR5-5600 profile uses 28-34-34 timings at 1.35V and may require enabling a supported XMP or EXPO profile.
Can I use fewer than four modules from the kit?
The product is supplied as a matched four-module kit. Kingston states that the kit warranty is void and returns are not accepted if the modules are sold or used separately. Follow the manufacturer's kit conditions.
Does the kit support AMD EXPO and Intel XMP?
Yes. The manufacturer specifies support for AMD EXPO 1.1 and Intel XMP 3.0. Actual profile availability depends on the platform and its firmware support.
