Eight black DDR5 RDIMM modules with silver heat spreaders in a row

Kingston Technology Corp.

Kingston Technology Corp. KF548R36RBK8-256 256GB 8x32GB DDR5 RDIMM 4800 CL36 server RAM

SKU CH-Y7VQ-7ZYSA MPN KF548R36RBK8-256

Eight 32 GB DDR5 RDIMM modules deliver 256 GB of registered ECC memory at 4800 MHz CL36 with a 1.10 V heat-spreader design

  • Capacity256GB (8 x 32GB)
  • Type288-Pin DDR5 RDIMM
  • SpeedDDR5 4800 (PC5 38400)
  • CAS LatencyCL36
  • Timing36-38-38
  • Voltage1.10V
  • 256 GB total capacity for large workloads
  • Eight 32 GB modules enable octo-channel bandwidth
  • DDR5 4800 speed with CL36 latency
  • Registered ECC design protects data integrity
  • 10 V operation reduces power draw

256GB DDR5 RDIMM octo-channel kit

This kit contains eight registered DDR5 modules totalling 256 GB. Each 32 GB stick runs at 4800 MHz with CL36 timings and on-board ECC. It is built for workstations and high-end desktops that require registered memory with error correction.

Registered ECC memory for data-integrity workloads

The registered design and ECC support suit creators, engineers and data-science professionals who need multi-bit error detection and correction. Systems that cannot accept 288-pin RDIMMs or that require unbuffered modules cannot use this kit.

4800 MHz CL36 speed and latency

The modules operate at DDR5-4800 with a CAS latency of 36 and a timing sequence of 36-38-38 at 1.10 V. This combination of frequency and latency determines whether the kit matches the platform’s qualified vendor list.

Questions about this item

Can these DDR5-4800 RDIMMs run with older DDR5 modules at 4800 MHz CL36?

Mixing kits is possible if the older modules are also DDR5 RDIMMs rated for 4800 MHz and CL36 timing; the system will default to the slowest common speed and latency.

How can I confirm the ECC and registered functions are active after installation?

The BIOS or UEFI memory-info screen should report ECC as enabled and show the modules as registered RDIMMs running at 4800 MHz with 36-38-38 timings.

Does the eight-module kit include only the 288-pin RDIMMs with heat spreaders, or are extra cables or brackets supplied?

The box contains exactly eight 32 GB DDR5 RDIMMs with integrated heat spreaders; no cables, brackets or additional accessories are included.
