Two green DDR5 RDIMM modules without heat spreaders

NEMIX RAM

NEMIX RAM 192GB (2x96GB) DDR5 6400 CL52 2Rx4 ECC RDIMM Supermicro X14SDV-32C-SP3F memory upgrade

SKU CH-D46T-EJWZJ

192 GB DDR5-6400 ECC RDIMM kit with two 96 GB modules, CL52 latency and 1.1 V operation, validated for Supermicro X14SDV-32C-SP3F motherboards

  • Total capacity192 GB (2 × 96 GB)
  • Rated speedDDR5 6400 (PC5 51200)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL52
  • Rated voltage1.1 V
  • Buffer typeRegistered

Size 192GB 2X96GB

  • 192 GB total capacity from two 96 GB modules for dense server workloads
  • DDR5 6400 speed with CL52 latency matches the motherboard's rated timing
  • Registered ECC design corrects single-bit errors and stabilises fully populated slots
  • 10 V operation and 2Rx4 organisation meet the board's exact electrical requirements
  • 288-pin RDIMM form factor fits the Supermicro X14SDV-32C-SP3F memory slots

Exact-match server upgrade

This 192GB kit uses two 96GB DDR5 RDIMMs built to the Supermicro X14SDV-32C-SP3F memory controller's exact rank, voltage and timing requirements. Registered ECC architecture lets every slot run fully populated at the rated 6400 speed while correcting single-bit errors before they reach production workloads.

Thermals and power in normal use

Modules operate at 1.1V without heat spreaders, relying on the server's directed airflow to maintain stable temperatures under continuous load. Registered buffering reduces electrical load on the memory controller, keeping power draw predictable when all channels are populated at the rated frequency.

Replaces smaller or slower DDR5 RDIMMs

The jump is worth it when your current configuration caps capacity below 192GB or runs at a lower data rate than PC5-51200, provided the motherboard manual confirms 96GB dual-rank modules in the required population order. Buyers who need UDIMM, SODIMM or non-ECC memory cannot use this kit.

Questions about this item

How do I install the 2Rx4 RDIMM modules in the Supermicro X14SDV-32C-SP3F and what step is often missed?

Insert both 96GB DDR5 6400 RDIMMs into the correct slots following the motherboard manual population order for 2Rx4 registered ECC modules, then verify the BIOS shows 192GB at 6400MHz CL52. The step often missed is checking the manual for the exact slot sequence required when fully populating the board.

What maintenance or replacement will the 288-pin DDR5 ECC RDIMM kit need over time?

The modules have no heat spreader and no moving parts, so no routine maintenance is required. Replacement is only needed if a module fails, which is covered by the lifetime replacement warranty and free US-based technical support.

What limit appears first when the 192GB DDR5 6400 CL52 kit runs sustained workloads on the X14SDV-32C-SP3F?

The registered 2Rx4 architecture offloads the memory controller so every slot runs fully populated at rated 6400MHz speed, while ECC corrects single-bit errors on the fly. The first practical limit is the motherboard's maximum supported capacity and population rules, not the modules themselves.
