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

NEMIX RAM

NEMIX RAM 128GB (4x32GB) DDR5 6400 CL52 1.1V ECC RDIMM SuperMicro AS-2116GT-HNTF memory upgrade

SKU CH-JPYW-W106K

128 GB registered ECC DDR5 kit with four 32 GB modules at 6400 MHz, CL52, 1.1 V, built for the SuperMicro GrandTwin AS-2116GT-HNTF

  • Total capacity128 GB (4 × 32 GB)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL52
  • Buffer typeRegistered
  • Rated voltage1.1 V
  • Memory rank2Rx8
  • 128 GB total capacity from four 32 GB modules
  • DDR5 6400 MHz speed for high-throughput workloads
  • ECC registered design protects data integrity in servers
  • Low 1.1 V operation reduces power draw
  • Validated for SuperMicro GrandTwin AS-2116GT-HNTF

Targeted Server Upgrade

This 128GB kit delivers four 32GB DDR5 RDIMM modules built for the SuperMicro GrandTwin A+ AS-2116GT-HNTF. Registered design and ECC protect data integrity in multi-socket workloads. The 1.1V operating voltage matches platform requirements exactly. Buyers needing consumer DIMMs or non-ECC memory should look elsewhere.

Capacity And Headroom

Four ranks of 2Rx8 chips provide 128GB total across 288-pin slots. CL52 latency at 6400 MT/s supports memory-intensive virtualization and database tasks. Bandwidth scales with populated channels on the target board. Systems requiring higher frequencies or lower latencies will not be satisfied by this specification.

Thermals And Power

Bare modules without heat spreaders rely on chassis airflow for cooling. The 1.1V DDR5 baseline keeps per-module power draw modest under typical server loads. Registered buffers add negligible overhead. Environments with restricted airflow or overclocking intent are not suited to this configuration.

Questions about this item

Will the 6400MHz DDR5 ECC RDIMM kit operate correctly alongside existing DDR5 modules in the SuperMicro AS-2116GT-HNTF?

The kit is validated for the SuperMicro AS-2116GT-HNTF; mixing with other DDR5 modules is not covered by the supplied compatibility data.

How can I verify the 128GB DDR5 6400 CL52 kit is running at its rated speed after installation?

Check the memory frequency and CL52 timing in the BIOS or use a system information tool to confirm 6400MHz operation.

What is included in the 128GB kit and are any extra components required for installation?

The box contains four 32GB DDR5 6400MHz ECC RDIMM modules; no additional parts are needed for installation in the compatible server.
