Exact-match DDR5 ECC RDIMM kit

This 384 GB kit contains eight 48 GB DDR5-4800 Registered ECC modules built to the 288-pin RDIMM form factor. It is specified for the Supermicro H13DSG-O-CPU motherboard and matches the board's required rank, voltage and timing so the memory controller recognises the full capacity at rated speed.

Registered architecture and low voltage

Registered buffering offloads the memory controller, allowing all slots to run fully populated at 1.1 V while ECC corrects single-bit errors on the fly. The modules operate at CL40 latency without a heat spreader, relying on the server chassis airflow for thermal management in normal operation.

Sustained-load stability

Under continuous workloads the registered design keeps each DIMM stable at the full 384 GB configuration, preventing the signal degradation that can occur with unbuffered modules in dense populations. ECC protection remains active throughout extended runs, stopping silent data corruption before it reaches production workloads.

Questions about this item

How do I install the 8x48GB DDR5 RDIMM kit into the Supermicro H13DSG-O-CPU, and which step do people get wrong?

Power down the server, open the chassis, and insert each 288-pin module into the slots listed in the motherboard manual following the exact population order; the step most often missed is seating both latches until they click, otherwise the registered buffer stays inactive and the system will not POST.

What maintenance or replacement will the 384GB DDR5 ECC RDIMM kit need later?

No routine maintenance is required; the modules have no heat spreaders and run at 1.10V, so only a failed DIMM would need replacement, which is covered by the lifetime replacement warranty.

What limit appears first when the 8x48GB DDR5-4800 CL40 kit runs sustained workloads?

The memory controller’s maximum supported capacity and ranked population rules for the H13DSG-O-CPU are reached before any thermal or voltage ceiling, so full 384GB operation depends on the board’s qualified vendor list and BIOS settings.
