Four green DDR5 RDIMM modules in a row

NEMIX RAM

NEMIX RAM 128GB (4x32GB) DDR5 6400 CL52 1.1V 2Rx8 ECC RDIMM Supermicro H13SSL-NT memory upgrade

SKU CH-FGJ4-NJTPC

A 128 GB DDR5-6400 ECC registered RDIMM kit of four 32 GB modules at CL52 and 1.1 V, validated for the Supermicro H13SSL-NT motherboard

  • Total capacity128 GB (4 × 32 GB)
  • Rated speedDDR5 6400 (PC5 51200)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL52
  • Rated voltage1.1 V
  • Buffer typeRegistered
  • 128 GB capacity across four 32 GB modules for maximum server density
  • DDR5 6400 speed with CL52 latency and 1.1 V operation for rated performance
  • Registered ECC RDIMM design offloads the controller and corrects single-bit errors
  • 288-pin 2Rx8 form factor matches Supermicro H13SSL-NT memory population rules
  • Built with major OEM Samsung, Micron or Hynix chips for enterprise reliability

Exact-match 128 GB DDR5 kit

This NEMIX RAM kit delivers 128 GB as four 32 GB DDR5 RDIMMs rated at 6400 MT/s with CL52 latency and 1.10 V operation. Each module is a 2Rx8 registered ECC DIMM built with major OEM chips for the Supermicro H13SSL-NT motherboard. The registered design lets the memory controller address every slot at full population without signal degradation.

288-pin RDIMM installation

The 288-pin registered form factor slots directly into the H13SSL-NT DIMM sockets; no heat spreader means standard clearance applies. Because population order and maximum capacity per channel differ by server revision, consult the system manual for the approved slot sequence before seating all four modules. Mixing ranks or voltages can prevent the board from training at the rated 6400 speed.

Enterprise workloads needing registered ECC

Suited for virtualization hosts, database nodes and other production servers that require error correction and full-capacity stability across every channel. Not appropriate for desktop boards that accept only unbuffered UDIMMs, for laptops or compact systems using SODIMMs, or for any platform that cannot run 1.10 V registered DDR5 at the specified timing.

Questions about this item

How can I confirm the kit is running at DDR5 6400 CL52 1.10V after installation?

Enter the server BIOS or UEFI and open the memory information screen. It should show all four slots populated, each DIMM at 32 GB, speed 6400 MT/s, CAS latency 52, voltage 1.10 V, and ECC enabled.

What ships in the box and is anything else required to use this memory?

The package contains four 32 GB DDR5 288-pin RDIMM modules for a total of 128 GB. No extra parts or cables are needed; the motherboard supplies power and the memory controller handles registration and ECC.

Which capacity or kit version should I choose for a Supermicro H13SSL-NT?

This 128 GB kit (4 × 32 GB, 2Rx8, PC5-51200) matches the board's DDR5 RDIMM population rules. Select it when the system manual lists 128 GB as a supported per-socket maximum and calls for registered ECC modules.
