NEMIX RAM 128GB DDR5 5600 CL46 4Rx4 1.1V RDIMM ECC memory upgrade

SKU CH-1GCS-FNFEE

128 GB DDR5 5600 CL46 4Rx4 1.1 V registered ECC RDIMM built for the Supermicro X14SDV-32C-SP3F motherboard

  • Capacity128GB
  • Type288-Pin DDR5 RDIMM
  • SpeedDDR5 5600 (PC5 44800)
  • CAS LatencyCL46
  • Voltage1.10V
  • ECCYes

Size 128GB

  • 128 GB capacity fills every slot on the Supermicro X14SDV-32C-SP3F
  • DDR5 5600 speed matches the board's rated memory bus
  • CL46 latency and 1.1 V keep timing within spec
  • Registered 4Rx4 design lets all channels run fully populated
  • ECC corrects single-bit errors to prevent silent data corruption

Exact-match server upgrade

This 128GB DDR5 RDIMM delivers PC5-44800 speed at CL46 with 1.1V registered ECC operation. The 4Rx4 organization and 288-pin form factor match the memory controller requirements for the Supermicro X14SDV-32C-SP3F motherboard.

Suits fully populated server builds

Ideal for administrators who need maximum capacity per slot in a registered ECC configuration. Not suitable for workstations or desktops that require unbuffered UDIMM modules or lower-density ranks.

Install by consulting the manual

Installation follows the motherboard's specific DIMM population order and capacity limits. Errors usually occur when slots are filled out of sequence or when mixed-rank modules prevent the system from recognizing the full 128GB.

Highlights

  • 128 GB capacity fills every slot on the Supermicro X14SDV-32C-SP3F
  • DDR5 5600 speed matches the board's rated memory bus
  • CL46 latency and 1.1 V keep timing within spec
  • Registered 4Rx4 design lets all channels run fully populated
  • ECC corrects single-bit errors to prevent silent data corruption

Questions about this item

What motherboard is required for this 128 GB DDR5 5600 4Rx4 registered ECC RDIMM to be recognised at full capacity?

It is verified for the Supermicro X14SDV-32C-SP3F motherboard, which expects a 288-pin RDIMM running at 5600 MHz PC5-44800 with 1.1 V and CL46 timing.

Will this 4Rx4 RDIMM work in a server that currently uses 2Rx4 modules?

Registered architecture offloads the memory controller so every slot can run fully populated, but population order and rank limits depend on the specific motherboard manual.

How can I confirm the kit is running at its rated 5600 MHz CL46 after installation?

Check the BIOS memory information screen or an OS tool such as dmidecode to verify speed shows 5600 MT/s, CAS latency 46, voltage 1.1 V and ECC enabled.
