NEMIX RAM 16GB DDR5 4800 ECC RDIMM 1Rx8 server RAM

SKU CH-6Q2B-M8XH3

16GB DDR5 4800 ECC RDIMM module with CL40 latency, 1.1V operation and 1Rx8 registered design for server motherboards

  • Total capacity16 GB
  • Rated speedDDR5 4800 (PC5 38400)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL40
  • Rated voltage1.1 V
  • Buffer typeRegistered

Capacity 16GB

  • ECC protects data integrity in server workloads
  • DDR5 4800 speed delivers high memory bandwidth
  • Registered signal buffering supports dense memory configurations
  • 1V operation reduces power draw per module
  • 1Rx8 single-rank layout simplifies memory population

16 GB DDR5 ECC RDIMM for servers

This 16 GB DDR5 module runs at 4800 MT/s with a CL40 latency and 1.10 V operating voltage. It uses a 288-pin RDIMM form factor with a 1Rx8 rank configuration and on-die ECC. The registered design adds a buffer for signal integrity in multi-module server platforms. No heat spreader is included.

Suited for registered DDR5 server boards needing ECC

This module fits servers and workstations that require registered DDR5 memory with error correction. It is not for desktop consumer boards that accept only unbuffered non-ECC DIMMs. Builders needing higher densities per slot or lower latency timings should look at other capacities or speed grades.

Installs in a 288-pin DDR5 RDIMM slot

The stick draws 1.10 V from the memory controller and presents a single 1Rx8 rank per channel. It frees the platform from using multiple lower-capacity modules to reach the same total memory. Ensure the motherboard firmware supports DDR5 4800 registered ECC before installation.

Questions about this item

Will my motherboard need a DDR5 RDIMM slot to accept this 288-pin 16 GB module?

Yes — the module is a 288-pin DDR5 RDIMM, so the board must provide a DDR5 registered DIMM socket.

Can I add this CL40 4800 MT/s stick to a server that already runs slower DDR5 ECC RDIMMs?

The module runs at DDR5 4800 with CL40; the system will down-clock all installed DDR5 RDIMMs to the lowest common speed and latency.

How do I confirm the stick is recognised as 16 GB ECC registered at 4800 MT/s after installation?

Check the BIOS memory info or run dmidecode — it should show 16 GB, DDR5 4800, ECC registered, 1Rx8 organisation.
