Exact-match DDR5 RDIMM for Supermicro H13SSF

This 128GB DDR5 5600 (PC5-44800) kit is a 2Rx4 Registered ECC module built to the exact rank, voltage and timing the H13SSF memory controller expects. It targets server administrators who need full-capacity population at rated speed without manual tuning.

Verify DIMM population rules before ordering

Consult the Supermicro H13SSF manual for supported capacities, approved slot order and installation steps because server memory support varies by model. The 288-pin RDIMM form factor is required; UDIMM or SODIMM modules will not fit or function in this platform.

Low-voltage registered design for dense configs

Operating at 1.10V with CL46 latency, the registered architecture offloads the memory controller so every slot runs fully populated while ECC corrects single-bit errors on the fly. No heat spreader is fitted, so airflow across the DIMM slots must follow the chassis manufacturer's guidance.

Questions about this item

Does the 128GB DDR5 5600 CL46 RDIMM arrive as a single module or a multi-stick kit and is any extra hardware required?

The package contains one 128GB 288-pin DDR5 ECC Registered RDIMM; no additional cables, brackets or cooling parts are needed for installation.

My Supermicro H13SSF has multiple DDR5 slots — should I choose this 128GB 2Rx4 CL46 module or a different capacity or rank?

This exact 128GB 2Rx4 CL46 1.1V module matches the board's qualified vendor list, so it will be recognised at full capacity and rated 5600 speed without manual tuning.

What does the PC5-44800 rating mean for real-world throughput once the DIMM is seated in the H13SSF?

PC5-44800 indicates a peak transfer rate of 44800 MB/s per module; with registered buffering and ECC the server sustains that bandwidth across all populated slots under load.
