NEMIX RAM 256GB 2x128GB DDR5-6400 CL52 4Rx4 RDIMM ECC Supermicro X14SDW-36C-SP9F

SKU CH-EAHY-CDFAX

256GB DDR5-6400 registered ECC kit (2×128GB, CL52, 1.1V, 4Rx4) validated for the Supermicro X14SDW-36C-SP9F motherboard

  • Capacity256GB (2 x 128GB)
  • Type288-Pin DDR5 RDIMM
  • SpeedDDR5 6400 (PC5 51200)
  • CAS LatencyCL52
  • Voltage1.10V

Size 256GB 2X128GB

  • 256 GB capacity with two 128 GB modules for maximum server memory density
  • DDR5 6400 speed rated at PC5-51200 for high-throughput workloads
  • Registered ECC design corrects single-bit errors to prevent silent data corruption
  • 4Rx4 organisation and 1.1 V voltage match the Supermicro X14SDW-36C-SP9F memory controller exactly
  • 288-pin RDIMM form factor fits the motherboard's registered DIMM slots without adapters

Exact-match 256GB DDR5-6400 kit

This 256GB kit contains two 128GB DDR5-6400 Registered ECC RDIMMs built to the Supermicro X14SDW-36C-SP9F memory controller specification. The modules run at 1.10V with CL52 latency and a 4Rx4 rank structure so the board recognises the full capacity at rated speed.

Sustained enterprise stability

Registered architecture buffers every address and command line, letting all slots stay fully populated without signal degradation during continuous workloads. On-die ECC corrects single-bit errors in real time, preventing silent data corruption and unplanned reboots on production systems.

Replaces partial or slower populations

The kit upgrades a partially filled board or slower DDR5 modules to the maximum validated 256GB at DDR5-6400. The jump is worth it when the workload demands full registered capacity and ECC integrity at the board's highest supported data rate.

Questions about this item

How much power does the 1.1V DDR5-6400 kit draw when the server runs all day?

Each module operates at 1.1V, the standard voltage for DDR5-6400 RDIMMs; total system power depends on CPU load and the Supermicro X14SDW-36C-SP9F motherboard's memory-controller efficiency.

What motherboard and memory slots are required for this 288-pin RDIMM kit to function?

The kit is validated for the Supermicro X14SDW-36C-SP9F motherboard, which must provide DDR5 RDIMM slots and follow the board's population rules for 4Rx4 registered modules.

Will the 4Rx4 registered ECC modules work alongside other DDR5 RDIMMs I might keep in the remaining slots?

Mixing ranks is possible only if the Supermicro X14SDW-36C-SP9F manual approves the specific population order; the board's memory controller must support 4Rx4 modules in every populated channel.
