Server DDR5 RDIMM kit

Kingston Fury Renegade Pro KF556R28RBEK4-64 is a quad-channel kit of four 16 GB modules giving 64 GB total capacity. Each module is a 288-pin DDR5 RDIMM with ECC and registered signal processing for data integrity in workstation and server platforms. The kit runs at 5600 MHz with CL28 timings at 1.35 V and includes an AMD EXPO profile.

Registered ECC DDR5 at 5600 MHz

The decisive specification is the registered ECC DDR5 interface operating at 5600 MHz with CL28 latency. This combination delivers the error correction and signal buffering required by multi-socket workstation boards while providing high bandwidth for compute-intensive workloads.

Suits professionals needing registered ECC capacity

This kit suits creators, engineers and data-science professionals who need 64 GB of registered ECC memory with overclockable profiles on compatible Intel or AMD workstation platforms. Builders whose motherboards require unbuffered UDIMMs or non-ECC modules should look at something else.

Questions about this item

How does the 5600 MT/s speed perform once the modules are installed in a real machine?

The kit runs at DDR5-5600 with CL28-34-34-89 timings at 1.35 V, and the AMD EXPO profile applies those settings automatically on supported platforms.

What does the DDR5 RDIMM registered interface mean for practical bandwidth limits?

The 288-pin registered DIMM uses a single-rank 1Rx8 layout with on-die ECC plus module-level ECC, delivering PC5-44800 throughput while the register buffers address and command signals for stability.

What physical space and slot layout does the 4 x 16 GB kit require?

Four 288-pin DDR5 RDIMM modules with integrated heat spreaders occupy four adjacent DIMM slots in a quad-channel configuration.
