768GB DDR5-4800 ECC RDIMM kit

This 12-module kit delivers 768GB of DDR5-4800 registered ECC memory built for the Supermicro H14DSH motherboard. Each 64GB module uses a 2Rx4 organisation, runs at 1.1V and carries CL40 timing. The registered design lets the memory controller address every slot at full population without signal degradation.

DDR5-4800 registered ECC limits

The DDR5-4800 standard caps this kit at PC5-38400 bandwidth and CL40 latency, so workloads that scale beyond that throughput will hit the interface ceiling. Registered buffering and ECC add a small command-cycle overhead compared with unbuffered non-ECC modules, which is the trade-off for full-capacity stability across all 12 slots.

12-module RDIMM installation

Installing 12 identical 288-pin RDIMMs means following the H14DSH population sequence exactly; skipping a prescribed slot or mixing ranks prevents the board from training at the rated 4800 speed. The modules have no heat spreaders, so airflow across the DIMM rows must be sufficient for sustained 1.1V operation.

Questions about this item

Should I choose the 12x64GB kit or a different capacity for my Supermicro H14DSH?

This 768GB kit provides 12 modules of 64GB each, filling all available slots for maximum capacity on the H14DSH. Verify your motherboard manual for supported population rules before installing.

What does the DDR5 4800 speed mean for real-world server performance?

The modules run at 4800MHz (PC5-38400) with CL40 latency at 1.1V, delivering the rated bandwidth and timing the H14DSH memory controller expects for stable, full-capacity operation.

How does the 288-pin RDIMM interface and ECC registration affect my system?

The 288-pin Registered DIMM format with 2Rx4 organization and ECC offloads the memory controller, enables full-slot population at 768GB, and corrects single-bit errors to prevent data corruption.
