Product identity

This Kingston FURY Renegade Pro kit supplies 64GB of DDR5 memory in four 16GB RDIMM modules. Registered signal buffering and on-board ECC protect data integrity while the CL36 timing and 5600 MT/s speed keep throughput high. It targets workstation and high-end desktop users who need server-grade reliability with enthusiast-class overclock headroom via Intel XMP 3.0 profiles.

Fit and alternatives

The kit suits professionals running memory-intensive workloads such as simulation, rendering or large-dataset analysis where ECC and registered buffering are required. Builders using consumer platforms that accept only unbuffered non-ECC UDIMMs cannot use these modules. Users needing capacities beyond 64GB or different latency targets should evaluate other configurations.

Deciding specification

The registered DDR5 RDIMM form factor with ECC support is the single attribute that determines compatibility. Only motherboards and processors that explicitly support registered ECC DDR5 will recognise and stabilise this memory. Verify platform documentation for RDIMM qualification before purchase.

Questions about this item

How much power does the 1.25 V DDR5-5600 kit draw when running all day?

Each module operates at 1.25 V with DDR5-5600 speed and CL36-38-38 timings; total system power depends on your platform and workload.

What platform features are required for this quad-channel RDIMM kit to function?

You need a workstation or high-end desktop motherboard with DDR5 RDIMM slots, registered DIMM support, ECC capability and an Intel XMP 3.0 compatible BIOS.

Can the registered ECC modules run alongside older non-ECC DIMMs I already own?

No — registered ECC RDIMMs must populate all channels with identical registered ECC modules; mixing with unbuffered or non-ECC memory is not supported.
