Four green DDR5 RDIMM modules with black chips, no heat spreaders

NEMIX RAM

NEMIX RAM 64GB (4x16GB) DDR5 4800 ECC RDIMM memory upgrade

SKU CH-91RT-K8SH3

Four 16 GB DDR5 4800 ECC registered DIMMs add 64 GB to compatible Supermicro servers

  • Capacity64GB (4 x 16GB)
  • SpeedDDR5 4800 (PC5 38400)
  • ECCYes
  • Buffered/RegisteredRegistered
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • Voltage1.10V
  • ECC protection prevents data corruption in critical workloads
  • 64GB capacity across four 16GB modules supports heavy multitasking
  • DDR5 4800 speed delivers high bandwidth for server tasks
  • Registered design with CL40 latency ensures stable signal integrity
  • 1V operation reduces power draw in dense configurations

Capacity and purpose

This 64GB kit supplies four 16GB DDR5 4800 registered DIMMs built for Supermicro UP SuperServer SYS-111C-NR and SYS-521C-NR platforms as well as the X13SEDW-F motherboard. It targets administrators who need error-correcting memory for mission-critical workloads.

Registered ECC advantage

Registered buffering reduces electrical load on the memory controller, while on-die ECC corrects single-bit errors before they reach the CPU. The combination keeps data integrity high during sustained server tasks without requiring additional software.

DDR5 4800 constraints

The modules run at 1.1V with CL40 latency and a single-rank 1Rx8 organisation, limiting maximum throughput to the PC5-38400 standard. Systems that demand higher frequencies or lower latencies cannot exceed this specification.

Points forts

  • ECC protection prevents data corruption in critical workloads
  • 64GB capacity across four 16GB modules supports heavy multitasking
  • DDR5 4800 speed delivers high bandwidth for server tasks
  • Registered design with CL40 latency ensures stable signal integrity
  • 1V operation reduces power draw in dense configurations

Questions sur cet article

Does the 1Rx8 DDR5 RDIMM layout affect future capacity upgrades?

Each module is a single-rank 16 GB stick, so the four installed DIMMs occupy four slots; adding more capacity later will require free slots or replacing existing modules.

What thermal limit appears first when the kit runs at 4800 MT/s continuously?

The modules operate at 1.10 V without heat spreaders, so sustained load will hit the DRAM junction temperature threshold before any voltage or power limit is reached.

How much power does the 64 GB kit draw at 1.1 V under all-day load?

At 1.1 V the four registered DIMMs typically draw roughly 13 W total when fully stressed, making cooling airflow the main design consideration.
