Four black DDR5 RDIMM modules with heat spreaders

Kingston Technology Corp.

Kingston Technology Corp. KF564R32RBE2K4-128 128GB (4×32GB) DDR5 6400 CL32 ECC RDIMM server RAM

SKU CH-ZS0R-KSKA3 MPN KF564R32RBE2K4-128

Four 32 GB DDR5 RDIMM modules deliver 128 GB of registered ECC memory at 6400 MT/s with CL32 latency and AMD EXPO support

  • Type288-Pin DDR5 RDIMM
  • SpeedDDR5 6400 (PC5 51200)
  • CAS LatencyCL32
  • Timing32-39-39
  • Voltage1.40V
  • 128GB total capacity handles heavy multi-tasking with four 32GB modules
  • 6400MHz DDR5 speed and CL32 latency deliver fast registered ECC performance

Server-Class DDR5 Memory Kit

This 128GB kit comprises four 32GB DDR5-6400 CL32 RDIMM modules designed for workstations and high-end desktops that require registered ECC memory. It targets creators, engineers and data-science professionals who need data-integrity features alongside high bandwidth.

AMD EXPO Profile Support

The modules ship with an AMD EXPO profile that automatically configures 6400MT/s speed, CL32-39-39 timings and 1.40V voltage on compatible platforms. Registered signal processing and on-die ECC combine with multi-bit error correction to maintain stability under sustained heavy workloads.

Suited for Registered-DIMM Platforms

This kit fits systems built around DDR5 RDIMM slots that support ECC and registered signalling. Builders using consumer boards that accept only unbuffered UDIMMs or platforms limited to lower voltages should choose a different memory type.

FeaturesKingston FURY KF564R32RBE2K4-128 is a kit of four 4G x 80-bit (32GB) DDR5-6400 CL32 SDRAM (Synchronous DRAM) 2Rx8, ECC memory module, based on twenty 2G x 8-bit FBGA components per module. The module supports AMD® EXPO v1.1 and 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 sur cet article

Will the 1.40 V operating voltage shorten the lifespan of the 128 GB DDR5 kit?

The modules are rated for continuous operation at 1.40 V with the installed heat spreader, so no extra maintenance or early replacement is expected under normal server workloads.

What limits sustained throughput first on these CL32 6400 MT/s RDIMMs?

The registered buffer and dual-rank 2Rx8 organisation set the practical ceiling; the memory controller reaches its timing budget before the DRAM chips hit thermal limits.

How much heat and noise do four 32 GB sticks produce when running all day at 6400 MT/s?

Each module draws 1.40 V with an integrated black heat spreader; total system fan noise depends on chassis airflow, but the DIMMs themselves add no audible noise.
