Four green DDR5 RDIMM modules in anti-static tray

NEMIX RAM

NEMIX RAM 128GB 4x32GB DDR5 5600 ECC Registered RDIMM CL46 1.1V Supermicro H13DSG-O-CPU

SKU CH-NTCG-TFPFN

A 128 GB kit of four 32 GB DDR5-5600 ECC Registered RDIMMs at CL46 and 1.1 V, validated for the Supermicro H13DSG-O-CPU motherboard

  • Total capacity128 GB (4 × 32 GB)
  • Rated speedDDR5 5600 (PC5 44800)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL46
  • Rated voltage1.1 V
  • Buffer typeRegistered
  • 128 GB total capacity from four 32 GB modules for maximum server density
  • DDR5 5600 speed with CL46 latency matches the motherboard's rated memory timing
  • Registered ECC architecture corrects single-bit errors and stabilises fully populated slots
  • 10 V operation at 2Rx8 rank aligns with the platform's memory controller spec
  • 288-pin RDIMM form factor fits the Supermicro H13DSG-O-CPU memory slots exactly

Exact-Match DDR5 Kit for Supermicro H13DSG-O-CPU

This 128GB kit contains four 32GB DDR5 5600 RDIMMs built to the precise rank, voltage and timing the Supermicro H13DSG-O-CPU memory controller expects. Registered ECC architecture with CL46 latency and 1.1V operation ensures the modules are recognised at full capacity and run at their rated PC5-44800 speed without manual tuning.

Registered ECC Architecture for Full Population

The 2Rx8 registered design offloads the memory controller so every slot runs fully populated at 128GB total, while on-die ECC catches and corrects single-bit errors before they reach production workloads. Modules use the 288-pin RDIMM form factor this board requires and contain major OEM chips from Samsung, Micron or Hynix without heat spreaders for dense server chassis clearance.

Suited for Verified Supermicro Upgrades

Buyers who need a drop-in, spec-matched memory upgrade for the named Supermicro motherboard will find the kit installs and posts at rated speed immediately. Builders using any other platform, desktop UDIMM slots, or systems that demand UDIMM or SODIMM form factors should look elsewhere because the registered pin-out and voltage are incompatible.

Questions about this item

Does the 1.1V DDR5 5600 kit hit a thermal throttle or power ceiling first under sustained full-load use?

The modules run at 1.1V with no heat spreader, so they rely on chassis airflow to stay within DDR5 5600 limits during continuous operation.

How much fan noise or case airflow is needed to keep the 4x32GB registered ECC DIMMs cool all day?

Without a heat spreader, the RDIMMs depend on standard server airflow; ensure front-to-rear cooling meets the motherboard's thermal design for 128GB populations.

What motherboard slot population rules must the Supermicro H13DSG-O-CPU already follow for this 288-pin RDIMM kit to work?

The board requires registered DDR5 RDIMMs in the validated population order — consult the Supermicro manual for the exact slot sequence and maximum capacity per channel.
