  • Total capacity1 TB (8 × 128 GB)
  • Rated speedDDR5 6400 (PC5 51200)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL52
  • Rated voltage1.1 V
  • Buffer typeRegistered
  • 1TB capacity for large workloads with 8×128GB modules
  • DDR5 6400 speed rated at PC5-51200 for high throughput
  • Registered ECC with 2Rx4 organisation corrects errors and offloads the controller
  • 1V operation at CL52 latency matches the board's memory controller
  • 288-pin RDIMM form factor verified for Supermicro H14DST-FL

Exact-match server kit

This 1 TB kit contains eight 128 GB DDR5 registered ECC RDIMMs built to the precise rank, voltage and timing the Supermicro H14DST-FL memory controller expects. The modules are recognised at full capacity and run at their rated speed without manual tuning.

Registered ECC integration

Registered architecture offloads the memory controller so every slot runs fully populated at full capacity, while ECC catches and corrects single-bit errors on the fly. The 288-pin RDIMM form factor matches the board's requirement and population rules; it is not a UDIMM or SODIMM.

1 TB headroom and limits

Eight dual-rank modules deliver 1 TB of addressable memory for virtualization, large databases and memory-intensive workloads. The kit stops at the board's maximum supported capacity and cannot scale beyond the eight populated slots.

Questions about this item

How does the CL52 latency affect throughput when all eight slots of the H14DST-FL are populated at 6400 MT/s?

CL52 is the rated timing the memory controller expects; with eight 2Rx4 RDIMMs installed the board runs at the full 6400 MT/s speed without down-clocking.

What thermal load should I plan for when this 1 TB kit runs continuously at 1.1 V in a fully loaded server?

The modules operate at 1.1 V without heat spreaders; registered buffering reduces electrical load on the controller, so typical airflow for a dense RDIMM population is sufficient.

Which motherboard revision and BIOS version are required before installing this 8 x 128 GB RDIMM kit in the H14DST-FL?

The kit is validated for the Supermicro H14DST-FL; consult the board manual for the approved DIMM population order and any BIOS update needed for full 1 TB capacity.
