Six green DDR5 RDIMM modules in anti-static tray

NEMIX RAM

NEMIX RAM DDR5 768GB 6x128GB 6400MHz CL52 1.1V ECC RDIMM Supermicro H13DSG-OM

SKU CH-7J7T-8KJ1P

A 768 GB DDR5 ECC registered memory kit of six 128 GB modules at 6400 MHz CL52, validated for the Supermicro H13DSG-OM motherboard

  • Capacity768GB (6 x 128GB)
  • Type288-Pin DDR5 RDIMM
  • SpeedDDR5 6400 (PC5 51200)
  • CAS LatencyCL52
  • Voltage1.10V
  • ECCYes
  • 768GB capacity across 6 modules for dense server workloads
  • DDR5 6400 speed with CL52 latency for rated performance
  • 1V registered ECC design reduces controller load and corrects errors
  • 2Rx4 288-pin RDIMM form factor matches Supermicro H13DSG-OM requirements
  • Major OEM Samsung, Micron or Hynix chips for enterprise-grade stability

Capacity and Compatibility

This kit delivers 768GB of DDR5 server memory across six 128GB RDIMM modules. It is built to the exact specifications required by the Supermicro H13DSG-OM motherboard, ensuring full-capacity recognition and rated-speed operation without manual tuning.

Fitment and Limitations

The registered ECC design suits administrators who need maximum density and error correction on this specific platform. Builders using consumer motherboards, workstations requiring UDIMMs, or systems that cannot accept 2Rx4 registered modules should select a different memory type.

Build Integration

Each 288-pin module operates at 1.1V with CL52 latency at DDR5-6400, matching the board's native voltage and timing tables. The registered architecture reduces electrical load on the memory controller when all slots are populated, while on-die ECC protects data integrity without consuming additional system resources.

Highlights

Questions about this item

What motherboard must I already own for this 768GB DDR5 6400MHz RDIMM kit to work?

This kit is verified for the Supermicro H13DSG-OM motherboard. It requires that specific board with DDR5 RDIMM slots supporting 128GB 2Rx4 modules at 1.1V.

Will these 128GB 2Rx4 modules run with smaller DDR5 RDIMMs I keep in other slots?

Mixing capacities or ranks is not recommended. The board's memory population rules require identical modules per channel for stable operation at 6400MHz.

How do I confirm the full 768GB is recognised at 6400MHz CL52 after install?

Check BIOS memory info or OS tools for 768GB total, 6400MT/s speed, CL52 timings, and ECC active on all six DIMMs.
