NEMIX RAM

NEMIX RAM 192GB (4 x 48GB) DDR5 6400 CL52 2Rx8 ECC Registered RDIMM memory upgrade for Supermicro H14DST-FL

SKU CH-QZA5-9HWV9

192 GB DDR5-6400 ECC registered RDIMM kit built for the Supermicro H14DST-FL motherboard

  • Total capacity192 GB (4 × 48 GB)
  • Rated speedDDR5 6400 (PC5 51200)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL52
  • Rated voltage1.1 V
  • Buffer typeRegistered
  • 192 GB total capacity from four 48 GB modules for dense server workloads
  • DDR5 6400 speed with CL52 latency keeps data moving at rated throughput
  • Registered ECC architecture corrects single-bit errors and stabilises fully populated slots
  • 1 V operation matches the Supermicro H14DST-FL memory controller specification
  • 288-pin RDIMM form factor fits the board's required DIMM slots exactly

Exact-match DDR5-6400 RDIMM kit

This 192GB kit delivers four 48GB DDR5-6400 registered ECC modules built to the Supermicro H14DST-FL memory controller's exact rank, voltage and timing requirements. Each 288-pin RDIMM runs at 1.10V with CL52 latency and a 2Rx8 organisation so the board recognises the full capacity at rated speed without manual tuning.

Replaces partial or mixed-capacity populations

The kit upgrades systems currently running fewer modules, lower-density DIMMs or mismatched ranks that force the controller to down-clock or limit usable slots. Populating all four channels with identical registered ECC modules removes those compromises and restores the bandwidth the platform was designed to deliver.

192GB registered ECC headroom

Four 48GB ranks provide the dense capacity needed for virtualisation hosts, in-memory databases and large-scale compute jobs while ECC corrects single-bit errors on the fly. Workloads that exceed 192GB or require unbuffered UDIMM form factors fall outside this kit's supported configuration.

Questions about this item

Will the 288-pin RDIMM modules fit the Supermicro H14DST-FL memory slots?

Yes, the kit uses the 288-pin Registered RDIMM form factor that the H14DST-FL requires; it is not a UDIMM or SODIMM.

What is the correct installation sequence for the four 48 GB modules on this board?

Consult the Supermicro H14DST-FL manual for the approved DIMM population order; the board's memory-controller rules dictate which slots must be filled first for full 192 GB operation.

Do these Samsung, Micron or Hynix chips need any firmware updates or thermal-pad replacement over time?

No firmware updates or thermal-pad changes are required; the modules run at 1.1 V with no heat spreader and rely on the server's standard airflow for cooling.
