768GB DDR5 ECC RDIMM kit for Supermicro H13SSF

This 768GB kit contains twelve 64GB DDR5 4800 registered ECC RDIMMs built to the exact rank, voltage and timing the Supermicro H13SSF memory controller expects. It targets administrators who need full-capacity population on that specific motherboard without manual tuning.

Sustained-load behaviour with registered ECC

Registered architecture buffers each command so all twelve slots operate at the rated 4800 MT/s when fully populated, while on-die ECC corrects single-bit errors in real time. The 1.10V operating point and CL40 latency remain stable across continuous workloads rather than throttling after a short burst.

Build and daily implications

Modules ship without heat spreaders, relying on server chassis airflow for cooling. The 288-pin RDIMM form factor fits only registered-DIMM slots, so the kit cannot be used in workstations or desktops that require unbuffered memory.

Questions about this item

How much power does the 1.1V DDR5 4800 kit draw when the Supermicro H13SSF runs fully populated all day?

Each module operates at 1.1V, the standard DDR5 voltage, so total power scales with the 12x64GB capacity your board's memory controller manages.

What must the Supermicro H13SSF motherboard already provide for this 288-pin RDIMM kit to function?

The board needs 12 DDR5 RDIMM slots wired for Registered ECC memory and a memory controller that accepts 2Rx4 modules at 4800 MT/s.

Will the 2Rx4 Registered ECC modules work in the same channels as any existing 1Rx4 or 2Rx8 RDIMMs I keep in the H13SSF?

Mixed-rank populations are governed by the motherboard's qualified-vendor list; the H13SSF manual specifies which slot combinations are validated.
