768GB DDR5 ECC RDIMM Kit for Supermicro H14DSG-O-CPU

This 12-module kit delivers 768GB of DDR5-6400 registered ECC memory built for the Supermicro H14DSG-O-CPU motherboard. Each 64GB module operates at 1.1V with CL52 latency and a 2Rx4 organisation. The 288-pin RDIMM form factor matches the board's registered DIMM slots exactly.

Sustained-load behaviour

Registered buffering reduces electrical load on the memory controller so all twelve slots can run fully populated at rated speed without signal degradation. ECC corrects single-bit errors on the fly, preventing silent data corruption during long compute runs. The 1.1V operating voltage keeps power draw predictable under continuous utilisation.

DDR5-6400 interface practical limits

The PC5-51200 interface provides the bandwidth ceiling for this configuration; actual throughput depends on the motherboard's memory-controller implementation and population rules. Mixing ranks or voltages beyond the specified 2Rx4 1.1V profile will prevent the kit from operating at its rated 6400MT/s. Consult the system manual for approved DIMM population order before installation.

Perguntas sobre este artigo

How much power does the 768GB kit draw at its rated 1.10V DDR5 speed?

Each 64GB module operates at 1.10V; total draw depends on how many of the 12 sticks are populated and the server's memory-controller load.

What motherboard slot type and population rules must my Supermicro H14DSG-O-CPU follow for this 12x64GB RDIMM kit?

The board requires 288-pin DDR5 RDIMM slots; install all 12 modules in the exact population order shown in the motherboard manual to reach 768GB at 6400MHz.

Will these CL52 6400MHz registered ECC modules run stably alongside older DDR5 RDIMMs that have different latencies or ranks?

Mixing ranks, latencies or voltages is not supported; the memory controller will downclock all slots to the slowest common settings, risking instability.
