H14SSF DDR5 ECC RDIMM Kit

This 128GB kit uses two 64GB DDR5 5600 registered ECC modules built for the Supermicro H14SSF motherboard. The 2Rx4 layout and 1.1V operation match the board's memory controller requirements so the full capacity is recognised at rated speed.

Capacity and Headroom

The 128GB total provides ample headroom for virtualisation hosts, large databases or memory-intensive analytics workloads running on a single H14SSF board. If your application grows beyond 128GB you would need a platform that supports higher per-slot density or more memory channels.

Thermals Noise and Power

Registered DDR5 modules run at 1.1V without heat spreaders, relying on chassis airflow to keep temperatures in check. Power draw scales with the 5600 MT/s data rate and 2Rx4 organisation, staying within standard RDIMM limits for dense server configurations.

Questions about this item

Will this 2Rx4 DDR5-5600 RDIMM kit work with the existing DDR5 modules already installed in my Supermicro H14SSF?

The kit matches the H14SSF's required 288-pin Registered ECC DDR5-5600 1.1V CL46 2Rx4 specification, so it will be recognised at full 128 GB capacity and run at rated speed when populated according to the board's memory-population rules.

How can I verify the kit is running at DDR5-5600 CL46 1.1V with ECC active after installation?

Enter the BIOS or use a hardware-information utility; the memory should report 5600 MT/s, CL46 timings, 1.1 V, Registered ECC mode, and the full 128 GB (2 x 64 GB) capacity.

What exactly ships in the box and is anything else required for installation?

The package contains the 128 GB (2 x 64 GB) DDR5-5600 CL46 1.1 V 2Rx4 288-pin ECC Registered RDIMM kit only; no additional cables, brackets or software are needed beyond a compatible Supermicro H14SSF motherboard.
