256GB DDR5 ECC RDIMM kit for Supermicro H13SSH

This 256GB kit contains sixteen 16GB DDR5 4800 RDIMM modules built to the exact rank, voltage and timing the Supermicro H13SSH memory controller expects. Registered ECC architecture lets every slot run fully populated at rated speed while correcting single-bit errors on the fly. It targets administrators who need maximum capacity in a single validated upgrade.

Verify motherboard population rules before ordering

The H13SSH manual defines supported capacities, approved DIMM population order and installation steps that differ by configuration. Only 288-pin Registered DDR5 modules are accepted; UDIMM or SODIMM variants will not fit or function. Confirm your firmware revision matches the board's qualified vendor list so the full 256GB is recognised at boot.

Sustained load stability with registered buffering

Registered buffering offloads the memory controller so all sixteen modules maintain DDR5 4800 throughput continuously without signal degradation. ECC correction operates transparently during extended workloads, preventing silent data corruption that can surface only after hours of full-capacity utilisation. The 1.1V operating voltage keeps power draw predictable across the entire kit.

Questions about this item

What comes in the box and do I need anything else?

The kit includes sixteen 16 GB DDR5 4800 CL40 1.1 V 288‑pin ECC Registered RDIMM modules, totalling 256 GB. No extra parts or cables are required for installation.

Should I choose this 256 GB kit or a smaller capacity for my Supermicro H13SSH?

This 16 x 16 GB kit fills every slot on the H13SSH and delivers the maximum supported capacity at DDR5‑4800. Select a smaller kit only if your workload does not need the full 256 GB.

What does the DDR5‑4800 CL40 rating mean once the modules are installed?

The memory will run at 4800 MT/s with a CAS latency of 40 cycles at 1.1 V, providing the exact speed and timing the H13SSH memory controller expects for stable, full‑capacity operation.
