  • Intel XMP 3.0 profiles enable automatic overclocking for peak performance
  • 40 V operation balances speed and power efficiency

64GB DDR5-6400 Registered ECC Kit

This Kingston FURY Renegade Pro kit delivers 64GB of DDR5-6400 memory across four 16GB Registered DIMMs. It targets creators, engineering professionals, and data scientists using next-generation Intel or AMD workstation and high-end desktop platforms that require DDR5 RDIMMs with ECC for data integrity.

Upgrading from standard JEDEC DDR5 RDIMMs

The kit operates at 6400 MHz with CL32-39-39 timings at 1.40V, enabled by Intel XMP 3.0 profiles. The jump is worthwhile when your workload benefits from higher bandwidth and lower latency than standard server memory provides, while retaining Registered ECC error correction for multi-bit error detection.

Installing four 288-pin RDIMMs

Modules install into standard 288-pin DDR5 RDIMM slots on compatible workstation or high-end desktop motherboards. Ensure the platform supports Registered ECC DDR5 and XMP 3.0 to activate the rated speed; otherwise the kit will fall back to standard JEDEC speeds. Builders needing non-registered UDIMMs or capacities beyond 64GB should look elsewhere.

Questions about this item

Will these 288-pin DDR5 RDIMMs fit my server board slots?

Each module is a standard 288-pin DDR5 RDIMM, so it fits any motherboard slot wired for DDR5 registered memory.

How do I enable the rated 6400 MHz speed with Intel XMP 3.0 on a workstation board?

Enter the BIOS, select the XMP 3.0 profile for this kit, save and reboot; the board will set 6400 MT/s, CL32-39-39 timings and 1.40 V automatically.

What ongoing care does the heat spreader on these 1Rx8 modules need?

Keep chassis airflow directed across the spreaders; dust them with compressed air during routine server cleaning to maintain thermal performance.
