Server DDR5 RDIMM kit for workstations

This Kingston Fury Renegade Pro kit delivers 128 GB across four 32 GB DDR5-6400 registered DIMMs with ECC and CL32 timings. It targets creators, engineers and data-science professionals who need high throughput without sacrificing data integrity on Intel or AMD platforms that require RDIMMs.

Registered ECC with on-die error correction

Each module uses 1Rx4 organisation and registered signalling to maintain stability at 6400 MHz while multi-bit ECC detects and corrects errors beyond the on-die single-bit correction built into every DDR5 component. The XMP 3.0 profile lets the system apply validated timings and voltage automatically.

288-pin RDIMM installation notes

Modules install in standard DDR5 RDIMM slots; the integrated heat spreader adds height, so verify cooler clearance before seating all four sticks. Populate slots according to the motherboard manual to enable quad-channel operation and ensure the XMP profile loads at the rated 1.35 V.

FeaturesKingston FURY KF564R32RBK4-128 is a kit of four 4G x 80-bit (32GB) DDR5-6400 CL32 SDRAM (Synchronous DRAM) 1Rx4, ECC memory module, based on twenty 4G x 4-bit FBGA components per module. The module supports Intel® Extreme Memory Profiles (Intel® XMP) 3.0. Total kit capacity is 128GB. Each module has been tested to run at DDR5-6400 at a low latency timing of 32-39-39 at 1.4V. The SPDs are programmed to JEDEC standard latency DDR5-4800 timing of 40-39-39 at 1.1V. Each 288-pin DIMM uses gold contact fingers.

Questions about this item

Will the 1.35V DDR5-6400 modules need any firmware updates or replacement parts over time?

The kit runs at 1.35V with Intel XMP 3.0 profiles; no firmware updates or replacement parts are required for normal operation.

What limits sustained throughput first on these CL32 1Rx4 RDIMMs?

The CL32-39-39 timings at DDR5-6400 set the latency floor that appears before bandwidth saturation under continuous load.

How much heat and noise do four 32GB registered DIMMs produce running all day?

Integrated heat spreaders dissipate heat silently; the modules add no audible noise and draw 1.35V within standard DDR5 power limits.
