1 TB Registered ECC Kit for Supermicro H14DSG-O-CPU

This 1 TB kit contains eight 128 GB DDR5 RDIMMs built to the exact rank, voltage and timing the Supermicro H14DSG-O-CPU motherboard expects. It is intended for administrators who need to fill every slot with fully supported capacity. Builders using consumer boards or unbuffered DIMMs cannot use this kit.

Registered 2Rx4 Architecture Matches Board

Each module is a 288-pin Registered DIMM with a 2Rx4 organisation, 1.1 V operating voltage and CL52 latency at DDR5-6400. The registered buffer offloads the memory controller so the board recognises the full 1 TB when all eight slots are populated. A UDIMM or SODIMM will not fit or function in this platform.

ECC Correction Prevents Silent Corruption Under

On-board ECC detects and corrects single-bit errors in real time, stopping silent data corruption and unplanned reboots during sustained workloads. The registered design maintains electrical stability across all populated slots, keeping the kit at its rated speed without throttling. Modules have no heat spreaders, so chassis airflow must handle thermal dissipation.

Questions about this item

What does the 6400MHz speed mean when the kit is installed in a Supermicro H14DSG-O-CPU?

The modules will run at DDR5-6400 with CL52 timings at 1.10V, delivering the rated bandwidth the board's memory controller expects when all eight slots are populated with these 2Rx4 registered DIMMs.

How does the 288-pin RDIMM interface limit what this kit can do in practice?

The registered 288-pin DDR5 RDIMM form factor is required by the H14DSG-O-CPU; it buffers address and command signals so the memory controller can drive all eight 128GB modules at full speed without signal degradation.

What physical space and power does the 8-module kit need to fit the motherboard?

Eight 288-pin RDIMM slots must be free on the H14DSG-O-CPU, and the board's 1.1V DDR5 supply must support the combined load of all eight 128GB 2Rx4 modules.
