Four green DDR5 RDIMM modules without heat spreaders

NEMIX RAM

NEMIX RAM MR51200-744K4 512GB (4x128GB) DDR5 6400 CL52 1.1V 4Rx4 ECC RDIMM memory upgrade

SKU CH-ZEGY-JE83V

512GB DDR5-6400 ECC registered RDIMM kit (4×128GB) verified for Supermicro X14SDV-36CE-SP3F at CL52 1.1V

  • Capacity512GB (4 x 128GB)
  • Type288-Pin DDR5 RDIMM
  • SpeedDDR5 6400 (PC5 51200)
  • CAS LatencyCL52
  • Voltage1.10V
  • ECCYes

Size 512GB 4X128GB

  • 512 GB total capacity from four 128 GB modules for high-density server workloads
  • DDR5-6400 speed with CL52 latency and 1.1 V operation for efficient data throughput
  • Registered ECC design with 4Rx4 organisation to correct single-bit errors and support full-slot populations
  • 288-pin RDIMM form factor validated for the Supermicro X14SDV-36CE-SP3F motherboard
  • Built with major OEM Samsung Micron Hynix DRAM chips for enterprise-grade reliability

Server-grade capacity upgrade

This 512GB kit delivers four 128GB DDR5 RDIMM modules rated at 6400MT/s with CL52 latency and 1.1V operation. It targets administrators scaling memory on Supermicro X14SDV-36CE-SP3F platforms that require registered ECC memory.

Replaces partial or slower populations

The kit fills all four channels with matched 4Rx4 modules so the memory controller sees a single validated configuration. The jump is worth it when workloads exceed current capacity or when mixed-rank populations force the board to downclock.

Fits registered DIMM slots on qualified boards

Each 288-pin module uses the registered architecture the X14SDV-36CE-SP3F expects, freeing the on-die controller from electrical load. ECC corrects single-bit errors in flight while the 1.1V baseline keeps power draw predictable. Verify the motherboard manual for approved population order before installation.

Questions about this item

Will the 288-pin RDIMM modules fit the Supermicro X14SDV-36CE-SP3F motherboard slots?

Yes, the kit uses the 288-pin DDR5 RDIMM form factor required by the X14SDV-36CE-SP3F, so each 128 GB module seats directly in the board's DDR5 DIMM slots.

What is the correct installation order for the four 128 GB sticks on this board?

The Supermicro X14SDV-36CE-SP3F manual defines a specific DIMM population sequence; you must follow that order so all 512 GB are recognised at DDR5-6400 with CL52 timings.

Do these registered ECC modules need any firmware updates or battery replacements over time?

No, the RDIMMs are passive hardware with no firmware or onboard battery; they run at 1.1 V and rely on the motherboard's memory controller for ECC and registered buffering.
