Twelve green DDR5 RDIMM modules in anti-static tray

NEMIX RAM

NEMIX RAM DDR5 6400 1.5TB 12x128GB ECC RDIMM CL52 1.1V 2Rx4 H13SSL-NT memory upgrade

SKU CH-KAPV-40KF3

1.5 TB DDR5 6400 ECC RDIMM kit with 12×128 GB modules for Supermicro H13SSL-NT

  • Capacity1.5TB (12 x 128GB)
  • Type288-Pin DDR5 RDIMM
  • SpeedDDR5 6400 (PC5 51200)
  • CAS LatencyCL52
  • Voltage1.10V
  • ECCYes
  • 5 TB total capacity from 12 modules of 128 GB each
  • DDR5 6400 speed with CL52 latency for rated server performance
  • 1 V registered ECC RDIMM architecture reduces controller load and corrects single-bit errors
  • 2Rx4 288-pin form factor matches Supermicro H13SSL-NT memory population rules
  • Major OEM Samsung, Micron or Hynix chips provide enterprise-grade component quality

Exact-match server upgrade

This 1.5TB kit delivers twelve 128GB DDR5 registered ECC modules rated at 6400MHz with CL52 latency and 1.1V operation. It targets administrators who need the precise rank, voltage, and timing the Supermicro H13SSL-NT memory controller expects for full-capacity recognition.

Capacity and headroom

Twelve 2Rx4 RDIMMs populate every slot at the board's maximum supported density while registered buffering offloads the controller for stable operation. The kit runs out when workloads demand more than 1.5TB or require speeds beyond the DDR5-6400 specification.

Build quality and daily implications

Major OEM Samsung, Micron, or Hynix chips provide enterprise-grade reliability without heat spreaders, relying on server chassis airflow for cooling. The 288-pin registered form factor locks into the H13SSL-NT's DDR5 slots, and ECC corrects single-bit errors on the fly to prevent silent data corruption during continuous production runs.

Questions about this item

Will this 1.5 TB kit run alongside any existing DDR5 6400 CL52 1.1 V registered ECC modules I keep in my Supermicro H13SSL-NT?

Yes — the kit matches the board's required DDR5 6400 (PC5-51200) speed, 1.1 V voltage, CL52 timing and 2Rx4 registered ECC specification, so identical modules will interleave correctly.

How can I confirm the full 1.5 TB is recognised and running at 6400 MT/s after installation?

Enter the BIOS or UEFI and check the memory information screen; it should show 12 x 128 GB detected, DDR5 6400 operating speed, 1.1 V voltage and ECC active.

Does the package include anything besides the twelve 128 GB RDIMMs, such as a heat spreader or installation tool?

The box contains only the twelve 288-pin DDR5 6400 CL52 1.1 V 2Rx4 registered ECC RDIMMs; no heat spreaders, tools or extra accessories are supplied.
