SKU CH-6B9J-DY5SF

128GB DDR5 4800 ECC registered RDIMM for server and workstation upgrades

  • Capacity128GB
  • Type288-Pin DDR5 ECC RDIMM
  • SpeedDDR5 4800 (PC5 38400)
  • CAS LatencyCL40
  • Voltage1.1V
  • ECCYes
  • 128 GB capacity enables large-scale virtualization and in-memory workloads
  • DDR5 4800 speed delivers high bandwidth for data-intensive server tasks

  • 1 V operation reduces power draw per module in dense configurations

Server Memory Upgrade

This 128GB DDR5 4800 ECC Registered RDIMM is built for workstations and servers that require error-correcting registered memory. It operates at 1.1V with CL40 latency and a 4Rx4 rank configuration across 288 pins. The module replaces Hynix parts HMCT04MEERA129N, HMCT04MEERA131N, HMCT04MEERA133N and HMCT04MEERA135N.

DDR5 4800 Interface Limits

The DDR5 4800 standard provides a PC5-38400 data rate that cannot be exceeded without platform support for higher JEDEC speeds. Registered DIMMs add a clock cycle of buffering that desktop consumer boards do not expect. Mixing this module with unbuffered or load-reduced ECC memory is not supported by the memory controller.

Replacing Older Registered DIMMs

This module upgrades systems currently running lower-capacity or slower registered ECC DDR5 DIMMs where the platform qualifies 128GB 4Rx4 parts at 4800 MT/s. The jump is worth it when the workload demands maximum registered memory density per slot and the server or workstation vendor lists these Hynix part numbers as compatible.

Bu ürünle ilgili sorular

How do I know if this 128GB DDR5 4800 CL40 4Rx4 RDIMM is the right capacity and rank for my server?

Choose this 128GB 4Rx4 module when your platform requires a single high-density registered DIMM at DDR5 4800 with CL40 latency and 1.1V operation.

What does the DDR5 4800 PC5-38400 rating deliver once the module is installed in a compatible server?

The module runs at 4800 MT/s, providing a peak bandwidth of 38400 MB/s per DIMM with CL40 timing and ECC error correction active.

How does the 288-pin DDR5 registered ECC interface limit real-world use in my system?

The 288-pin RDIMM form factor fits only DDR5 server and workstation boards that support registered ECC memory; it cannot be used in unbuffered or consumer platforms.
