Eight green DDR5 RDIMM modules in anti-static tray

NEMIX RAM

NEMIX RAM 1TB (8×128GB) DDR5 4800 CL40 1.1V 4Rx4 ECC RDIMM memory upgrade

SKU CH-A3YR-8BZR9

Eight 128 GB DDR5 registered ECC modules at 4800 MT/s CL40, 1.1 V, 4Rx4, for Supermicro SYS-111C-NR, SYS-521C-NR and X13SEDW-F servers

  • Capacity1TB (8 x 128GB)
  • SpeedDDR5 4800 (PC5 38400)
  • ECCYes
  • Buffered/RegisteredRegistered
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • Voltage1.10V
  • 1TB capacity across eight 128GB modules for high-density server workloads
  • DDR5 4800 speed with CL40 latency delivers responsive registered memory performance
  • ECC registered design with 4Rx4 organisation ensures data integrity under heavy load
  • 10V operating voltage reduces power draw in dense Supermicro configurations
  • Validated for SuperMicro SYS-111C-NR SYS-521C-NR and X13SEDW-F platforms

Targeted Server Memory Upgrade

This 1 TB kit delivers eight 128 GB DDR5 4800 RDIMMs built for Supermicro UP SuperServer SYS-111C-NR and SYS-521C-NR platforms. Registered ECC operation and a 1.1 V profile provide the stability demanded by mission-critical workloads.

Capacity and Headroom

The 4Rx4 organisation across all modules yields a full terabyte of addressable memory, allowing large in-memory databases and virtualisation clusters to scale without swapping. CL40 latency at 4800 MT/s sustains throughput until the memory controller or CPU core count becomes the limiting factor.

Upgrade Path and Fit

The kit replaces lower-density RDIMM populations or mixed-speed DIMMs that force the system to downclock. The jump is worthwhile when the workload exceeds current capacity or when registered ECC is required for data integrity on X13SEDW-F motherboards. Buyers needing unbuffered DIMMs or non-ECC modules should look elsewhere.

Questions sur cet article

Will the 4Rx4 DDR5 4800 RDIMMs work alongside any existing DDR5 modules already installed in my Supermicro SYS-111C-NR?

The kit is validated for Supermicro SYS-111C-NR and SYS-521C-NR platforms. For best stability, populate all eight slots with this matched 1TB kit rather than mixing ranks or speeds.

How can I confirm the 1TB DDR5 4800 kit is running at CL40 1.10V after installation?

Enter the system BIOS or use a tool like CPU-Z to verify the memory reports DDR5 4800 MT/s, CL40 timings and 1.10V operating voltage across all eight modules.

Does the package include only the eight 128GB RDIMMs or are any cables or brackets supplied?

The box contains the 1TB kit — eight 128GB 288-pin DDR5 4800 CL40 4Rx4 ECC RDIMMs. No cables, brackets or additional hardware are included.
