Exact-match DDR5 ECC RDIMM kit

This 128GB kit contains four 32GB DDR5-5600 registered ECC modules built to the precise 2Rx8 rank, 1.10V voltage and CL46 timing the Supermicro H13SST-G memory controller expects. It installs as a matched set so the server recognises the full capacity at rated speed without manual tuning.

Thermals and power in normal use

Operating at the standard 1.10V DDR5 voltage, the modules draw minimal power and run without a heat spreader, relying on the server chassis airflow. Registered buffering reduces electrical load on the memory controller, keeping temperatures stable even when all four slots are populated under sustained workloads.

What the kit changes for your server

The registered ECC architecture offloads the memory controller and corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots in production. Buyers needing unbuffered UDIMMs, SODIMM form factors or non-ECC memory for workstation boards cannot use this kit.

Questions about this item

How do I install the 288-pin DDR5 RDIMM modules in the Supermicro H13SST-G, and which slot order do people often get wrong?

Power down the server, open the chassis, and insert each 32 GB module into the DIMM slots following the population sequence shown in the Supermicro H13SST-G manual; the common mistake is filling slots out of order, which prevents the 128 GB kit from being recognised at DDR5-5600.

What maintenance or replacement will the 2Rx8 registered ECC RDIMMs need over time?

The modules have no moving parts or heat spreaders, so no routine maintenance is required; if a single-bit error becomes uncorrectable, ECC will log the event and the affected 32 GB DIMM should be replaced under the lifetime replacement coverage.

What limit appears first when the 1.1 V CL46 kit runs sustained workloads on the H13SST-G?

The registered buffer and 2Rx8 organisation keep electrical loading within spec, so the first ceiling you hit is the DDR5-5600 data rate — the memory controller will not push beyond 5600 MT/s regardless of cooling or voltage headroom.
