NEMIX RAM 16GB DDR5 4800 ECC RDIMM CL40 1Rx8 1.1V memory upgrade

SKU CH-48QE-50JJ8

16 GB DDR5-4800 ECC registered RDIMM for Hynix-compatible servers at 1.1 V, CL40, single-rank 1Rx8

  • Capacity16GB
  • SpeedDDR5 4800 (PC5 38400)
  • ECCYes
  • Buffered/RegisteredRegistered
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • Voltage1.10V
  • ECC protection prevents data corruption in critical workloads
  • Registered design reduces electrical load for stable server operation
  • 4800 MT/s DDR5 bandwidth accelerates memory-intensive applications
  • 1 V operation lowers power draw per module
  • 1Rx8 single-rank layout simplifies population rules for Hynix platforms

Capacity and interface

This 16 GB DDR5 module runs at 4800 MT/s with a PC5-38400 rating. It uses a 288-pin RDIMM form factor and operates at 1.1 V with CL40 latency. The single-rank 1Rx8 design includes ECC and registered buffering for data integrity.

Suited for registered ECC servers.

This memory targets servers and workstations that require registered ECC DDR5 RDIMMs compatible with Hynix HMCG78MEBRA107N, HMCG78MEBRA113N, HMCG78MEBRA174N and HMCG78MEBRA115N part numbers. It will not work in consumer desktop or laptop platforms that accept only unbuffered non-ECC UDIMMs.

Registered ECC RDIMM decides fit

The registered ECC RDIMM architecture is the single specification that determines compatibility. Only motherboards with a registered DDR5 memory controller supporting ECC and the correct Hynix part-number validation can use this module.

Questions about this item

Should I choose the 1Rx8 16GB module or a different rank configuration for my Hynix server?

The 1Rx8 single-rank design on this 16GB module works with Hynix part numbers HMCG78MEBRA107N, HMCG78MEBRA113N, HMCG78MEBRA115N and HMCG78MEBRA174N for direct compatibility.

What does the 4800MHz speed deliver in an actual server workload?

DDR5 4800 (PC5-38400) runs at 4800MT/s with CL40 latency at 1.1V, providing registered ECC throughput suited for sustained server tasks.

How does the DDR5 RDIMM interface limit performance in practice?

The 288-pin DDR5 RDIMM interface registers commands and supports ECC, capping usable bandwidth at the rated PC5-38400 while adding signal integrity for multi-DIMM server channels.
