32 GB DDR5 4800 ECC RDIMM with CL40 latency and 1.1 V operation for registered server motherboards

  • Total capacity32 GB
  • Rated speedDDR5 4800 (PC5 38400)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL40
  • Buffer typeRegistered
  • Rated voltage1.1 V
  • ECC protection prevents data corruption in critical workloads
  • Registered signal buffering enables stable operation on server motherboards

32GB DDR5 4800 ECC RDIMM

This 32GB DDR5 4800 ECC RDIMM module operates at 1.1V with CL40 latency and a 1Rx4 configuration. It is a 288-pin registered DIMM designed for compatible server and workstation platforms. The part carries model reference HMCG84MEBRA116N and uses major OEM DRAM chips.

Registered ECC for servers and workstations

This module suits IT professionals upgrading Hynix-compatible servers or workstations that require registered ECC memory. It is not for buyers who need unbuffered UDIMMs, non-ECC memory, or modules with heat spreaders for consumer desktop builds.

DDR5 4800 speed and registered ECC

The decisive specification is the DDR5 4800 registered ECC RDIMM format with 1.1V voltage and CL40 timing. Verify your system requires registered ECC DDR5 at this speed before purchasing, as incompatible platforms will not accept this module.

Questions about this item

What motherboard slot and voltage does this 288-pin DDR5 RDIMM require?

The module fits a 288-pin DDR5 RDIMM slot and operates at 1.1 V; the platform must support registered ECC DDR5 at that voltage.

Can I add this 1Rx4 CL40 registered ECC module alongside existing DDR5 RDIMMs of different rank or latency?

Mixing is possible only if the motherboard and BIOS support mixed-rank and mixed-latency populations; the module itself is 1Rx4 CL40 at 4800 MT/s.

How can I verify the module runs at its rated 4800 MT/s CL40 after installation?

Check the BIOS memory information or an OS tool such as dmidecode to confirm speed shows 4800 MT/s and CAS latency 40.
