Sixteen green DDR5 RDIMM modules in a row

NEMIX RAM

NEMIX RAM DDR5 5600 256GB 16x16GB ECC RDIMM CL46 1.1V Supermicro H14SST-G

SKU CH-0KJA-S0BXB

256GB DDR5-5600 registered ECC server kit of sixteen 16GB RDIMMs at CL46 and 1.1V, validated for the Supermicro H14SST-G motherboard

  • Total capacity256 GB (16 × 16 GB)
  • Rated speedDDR5 5600 (PC5 44800)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL46
  • Rated voltage1.1 V
  • Buffer typeRegistered
  • 256 GB total capacity lets you fully populate the Supermicro H14SST-G with 16 modules
  • DDR5-5600 speed delivers PC5-44800 bandwidth for memory-intensive server workloads
  • Registered ECC architecture offloads the memory controller and corrects single-bit errors on the fly
  • 1 V operation at CL46 matches the board's exact voltage and timing requirements
  • 288-pin RDIMM form factor with 1Rx8 rank configuration ensures verified fitment and full-speed recognition

Exact-Match Server Upgrade

This 256GB kit contains 16 DDR5 RDIMM modules rated at 5600MHz PC5-44800 with CL46 latency and 1.1V operation. Each 16GB stick uses a 1Rx8 registered ECC design built with major OEM chips. The kit is specified for the Supermicro H14SST-G motherboard.

Build Integration

The 288-pin registered DIMM format matches the board's required slot type and memory population rules. Registered architecture buffers the command bus so all 16 slots can run fully populated at rated capacity. On-die ECC corrects single-bit errors without halting the system.

Thermals and Power

Modules operate at 1.10V standard DDR5 voltage with no heat spreaders installed. Registered buffering reduces electrical load on the memory controller during sustained workloads. Passive cooling relies on chassis airflow across the bare PCB.

Questions about this item

What is the CAS latency of the DDR5 5600 modules in this 256GB kit?

Each 16GB module runs at CL46 latency, the timing the Supermicro H14SST-G memory controller expects for DDR5-5600 operation.

How much power do the registered ECC DIMMs draw when the server runs continuously?

The kit operates at 1.1V, and the registered architecture reduces electrical load on the memory controller during sustained full-capacity use.

Which motherboard must already be installed for this memory kit to function?

The kit is verified for the Supermicro H14SST-G motherboard and requires its 288-pin RDIMM slots and registered-DIMM population rules.
