Four green DDR5 RDIMM modules in a row

NEMIX RAM

NEMIX RAM DDR5 5600 256GB (4×64GB) CL46 1.1V 2Rx4 ECC RDIMM Supermicro X14SDV-42C-SP3F memory upgrade

SKU CH-NTZD-HB0NX

256 GB DDR5 server kit with four 64 GB ECC registered RDIMMs at 5600 MHz, CL46, 1.1 V, validated for the Supermicro X14SDV-42C-SP3F

  • Total capacity256 GB (4 × 64 GB)
  • Rated speedDDR5 5600 (PC5 44800)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL46
  • Rated voltage1.1 V
  • Buffer typeRegistered

Size 256GB 4X64GB

  • 256 GB total capacity from four 64 GB modules for dense server workloads
  • DDR5-5600 speed rated at PC5-44800 delivers high bandwidth for data-intensive tasks
  • Registered ECC design with 2Rx4 organization offloads the memory controller and corrects single-bit errors
  • 1 V operating voltage matches the platform specification for stable full-population operation
  • Verified compatibility with the Supermicro X14SDV-42C-SP3F motherboard ensures correct fit and recognition

Exact-match DDR5 upgrade kit

This 256 GB kit consists of four 64 GB DDR5-5600 registered ECC RDIMMs built to the precise 2Rx4 rank, 1.1 V and CL46 specification the Supermicro X14SDV-42C-SP3F memory controller expects. The modules are recognised at full capacity and run at their rated speed without manual tuning.

Four-slot population for maximum density

Each 288-pin RDIMM plugs directly into a DIMM slot on the motherboard; the registered architecture buffers address and command signals so all four slots can be populated at full density without overloading the controller. No heat spreader is fitted, leaving the modules compatible with standard server airflow and heatsink clearances.

Enterprise stability at stock voltage

ECC circuitry detects and corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots in production workloads. The kit operates at the standard 1.1 V DDR5 voltage, drawing no more power than the board's memory subsystem is designed to deliver.

Questions about this item

Will the 1.1 V voltage limit throttle performance under sustained heavy workloads?

The kit runs at the standard DDR5 1.10 V specification; voltage is not a throttle point under normal sustained use.

How much heat do the four 64 GB modules generate when the server runs all day?

These registered ECC RDIMMs have no heat spreader; they rely on the chassis airflow the Supermicro X14SDV-42C-SP3F provides for cooling.

Does the Supermicro X14SDV-42C-SP3F motherboard need a specific BIOS version or CPU to recognise the full 256 GB kit?

The modules are spec-matched to the X14SDV-42C-SP3F at DDR5 5600 CL46 2Rx4; consult the board manual for population order and any firmware requirements.
