  • 1TB capacity across eight 128GB modules for maximum server density
  • DDR5-6400 CL52 at 1.1V matches the memory controller's exact timing
  • Registered ECC RDIMM architecture corrects single-bit errors and buffers every slot
  • 2Rx4 dual-rank organisation enables full 1TB population on supported boards
  • Validated for Supermicro H14DSG-OD motherboard with 288-pin RDIMM form factor

Exact-match server upgrade

This 1 TB kit contains eight 128 GB DDR5 RDIMMs rated at 6400 MT/s with CL52 latency and 1.1 V operation. The 2Rx4 registered ECC modules are built to the precise rank, voltage and timing the Supermicro H14DSG-OD memory controller expects for full-capacity recognition.

Build integration

The 288-pin RDIMM form factor matches the board's registered DIMM slots; UDIMM or SODIMM modules will not fit. Registered buffering offloads the memory controller so every slot can run fully populated, while on-die ECC corrects single-bit errors before they reach production workloads.

Sustained load behaviour

Enterprise-grade registration and ECC maintain stability when all eight slots operate continuously at rated speed. The 1.1 V baseline keeps power draw predictable during extended compute runs, and the lifetime replacement warranty backs long-term deployment.

Questions about this item

Will the 1.1 V operating voltage cause thermal throttling when all eight DIMMs run continuously?

The modules run at 1.10 V and are registered ECC RDIMMs, a design that reduces electrical load on the memory controller and helps maintain stable temperatures during sustained full-capacity operation.

What level of fan noise should I expect when the kit operates at DDR5-6400 CL52 around the clock?

These DIMMs have no heat spreaders and no active cooling, so they add no fan noise themselves; system acoustics will depend entirely on the server chassis and its fan curves.

Does my Supermicro H14DSG-OD motherboard need a specific BIOS revision or CPU stepping to recognise the full 1 TB capacity?

The kit is verified for the Supermicro H14DSG-OD motherboard; consult the board manual for the approved DIMM population order and any BIOS version requirements before installation.
