  • Rated speedDDR5 6400 (PC5 51200)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL52
  • Rated voltage1.1 V
  • Buffer typeRegistered
  • 192 GB capacity from two 96 GB modules
  • DDR5 6400 speed with CL52 latency
  • Registered ECC design corrects single-bit errors
  • 1 V operation matches server specifications
  • 288-pin RDIMM form factor fits Supermicro H14SST-GE

Exact-match server kit

This 192GB DDR5 kit delivers two 96GB Registered ECC RDIMMs rated at 6400 MT/s with CL52 latency and 1.1V operation. The modules use a 2Rx4 organisation that matches the memory controller expectations of the Supermicro H14SST-GE motherboard.

Fits H14SST-GE slots

The 288-pin RDIMM form factor installs directly into the server's registered DIMM slots; no UDIMM or SODIMM alternative will work. Registered buffering lets every populated slot run at full capacity while on-die ECC corrects single-bit errors before they affect workloads.

For Supermicro H14SST-GE upgrades

Administrators expanding that specific platform to 192GB with validated timings should use this kit. Builders targeting other motherboards, consumer platforms, or non-ECC unbuffered memory should look elsewhere.

Questions about this item

How does the 1.1V operating voltage affect thermal headroom when all slots stay populated 24/7?

The modules run at 1.1V with no heat spreader, relying on chassis airflow to keep temperatures in check during continuous operation.

What sustained power draw should I budget for the 192GB kit at DDR5 6400?

Each 96GB RDIMM draws roughly 5 to 7 watts at 6400 MT/s, so plan for about 10 to 14 watts total for the pair under full load.

Does the Supermicro H14SST-GE require a specific BIOS version or CPU stepping to recognise 96GB 2Rx4 RDIMMs at 6400?

The board must support DDR5-6400 Registered ECC 2Rx4 modules; consult the motherboard manual for the exact BIOS revision and approved population order before installing.
