Exact-match DDR5 server kit

This 64GB kit contains four 16GB DDR5 4800 Registered ECC RDIMMs built to the Supermicro H13SSF motherboard's specifications. The modules run at 1.1V with CL40 timing and a 1Rx8 rank layout so the memory controller recognises full capacity at rated speed.

Registered ECC stability

Registered architecture buffers the command bus, allowing every slot to stay populated at full capacity without overloading the controller. On-die ECC corrects single-bit errors in real time, preventing silent data corruption and unplanned reboots in production workloads.

Capacity and headroom

Four modules deliver 64GB across all channels, giving headroom for virtualisation, databases and large dataset processing. The kit reaches its limit when the board's maximum supported capacity or channel population rules are exceeded, so consult the manual before adding further DIMMs.

Questions about this item

Will the 1.1V registered DIMMs need replacement under sustained server loads?

The modules are rated for continuous operation at 1.10V with registered buffering and ECC; no scheduled replacement interval is defined by the manufacturer.

What limit appears first when all four 1Rx8 modules run at DDR5-4800 continuously?

The memory controller on the Supermicro H13SSF governs maximum sustained throughput; the kit operates at its rated CL40 timing within the board's qualified population rules.

How much heat and noise do the 288-pin RDIMMs generate during all-day operation?

The modules have no heat spreaders and draw 1.10V; thermal output is managed by the server's chassis airflow, and solid-state DRAM produces no audible noise.
