Two green DDR5 RDIMM modules with black chips, no heat spreaders

NEMIX RAM

NEMIX RAM 128GB 2x64GB DDR5 6400 CL52 4Rx4 ECC RDIMM Supermicro X14SDV-32C-SP3F memory upgrade

SKU CH-FQQ1-881PK

128 GB DDR5 registered ECC server memory kit, two 64 GB modules at 6400 MT/s CL52 1.1 V 4Rx4, validated for the Supermicro X14SDV-32C-SP3F motherboard

  • Capacity128GB (2 x 64GB)
  • Type288-Pin DDR5 RDIMM
  • SpeedDDR5 6400 (PC5 51200)
  • CAS LatencyCL52
  • Voltage1.10V
  • ECCYes

Size 128GB 2X64GB

  • 128 GB total capacity with two 64 GB modules for full memory population
  • DDR5 6400 speed delivers 51200 MT/s bandwidth for high-throughput workloads
  • Registered ECC architecture corrects single-bit errors to prevent data corruption
  • 4Rx4 quad-rank design matches the motherboard's memory-controller expectations exactly
  • 1 V operation at CL52 latency meets the platform's voltage and timing requirements

Compatible DDR5 128GB RDIMM kit

This 128GB kit contains two 64GB DDR5 6400 CL52 4Rx4 ECC Registered RDIMMs built for the Supermicro X14SDV-32C-SP3F motherboard. It targets server administrators who need exact-match capacity and registered stability for production workloads.

Verify board population rules

Confirm the motherboard manual for supported capacities, approved DIMM population order, and installation steps before ordering. The board requires 288-pin Registered RDIMMs, not UDIMMs or SODIMMs, and population rules determine whether both modules run at rated speed.

Replaces smaller or slower DDR5 RDIMMs

The upgrade is worth it when current modules limit total capacity or force lower data rates, and the manual confirms dual 64GB 4Rx4 Registered ECC DIMMs at DDR5 6400 with CL52 timing at 1.1V.

Preguntas sobre este artículo

What comes in the 128GB kit and do I need anything else to install it?

The kit contains two 64GB DDR5 6400 RDIMM modules. No extra parts are required; they fit the 288-pin slots on the Supermicro X14SDV-32C-SP3F motherboard.

Why choose the 4Rx4 128GB kit instead of a lower-rank option?

The 4Rx4 organization matches the memory controller expectations of the Supermicro X14SDV-32C-SP3F, allowing full-capacity recognition and rated DDR5 6400 operation.

What does the CL52 6400 rating mean once the modules are running in the server?

CL52 is the CAS latency at DDR5 6400 speed; the registered ECC design keeps all slots stable at that timing while correcting single-bit errors during operation.
