Twelve green DDR5 RDIMM modules in anti-static tray

NEMIX RAM

NEMIX RAM DDR5 ECC RDIMM 1.5TB (12×128GB) 6400MHz CL52 1.1V 2Rx4 Registered Supermicro H13DSH

SKU CH-YA7C-FQKWS

A 1.5 TB DDR5 ECC registered RDIMM kit of twelve 128 GB modules running at 6400 MHz CL52 and 1.1 V, validated for the Supermicro H13DSH motherboard

  • Capacity1.5TB (12 x 128GB)
  • Type288-Pin DDR5 RDIMM
  • SpeedDDR5 6400 (PC5 51200)
  • CAS LatencyCL52
  • Voltage1.10V
  • ECCYes
  • 5 TB total capacity from twelve 128 GB modules for maximum server density
  • DDR5 6400 MHz speed rated at CL52 latency for responsive data throughput
  • Registered ECC architecture corrects single-bit errors to protect data integrity
  • 1 V operating voltage reduces power draw across fully populated slots
  • Validated for Supermicro H13DSH motherboard to ensure full-speed recognition

Capacity and fitment

This kit supplies 1.5TB of DDR5 memory across twelve 128GB registered DIMMs. It is built for the Supermicro H13DSH motherboard and matches the board's required 288-pin RDIMM form factor.

Pre-installation checks

Verify the motherboard manual for approved DIMM population order and maximum supported capacity per channel. Confirm the system firmware is current enough to recognise the full 1.5TB configuration at the rated speed.

Thermals and power

Modules operate at 1.1V without heat spreaders, relying on server chassis airflow for cooling. Registered buffering reduces electrical load on the memory controller when all twelve slots are populated.

Questions about this item

Does the 1.5TB kit ship as twelve individual 128GB modules, or do I need to buy any extra DIMMs?

The kit contains twelve 128GB DDR5 RDIMMs for a total of 1.5TB, so no additional modules are required to reach that capacity.

Should I choose this CL52 6400MHz registered ECC kit or a lower-latency unbuffered alternative for the Supermicro H13DSH?

The H13DSH requires registered ECC RDIMMs; this CL52 6400MHz kit matches the board's validated population rules and voltage.

Will the DDR5-6400 rating run at full speed on a fully populated H13DSH, or does it downclock?

The modules are spec-matched to the H13DSH memory controller, so all twelve slots operate at DDR5-6400 with CL52 timings at 1.1V.
