Exact-match DDR5 server kit

This 128GB kit contains four 32GB DDR5 6400 Registered ECC RDIMMs built to the precise rank, voltage and timing the Supermicro H13SSL-N memory controller expects. The modules arrive as a matched set so the board recognises the full capacity at rated speed.

288-pin Registered form factor

The 288-pin RDIMM design fits the Supermicro H13SSL-N slots and is not interchangeable with UDIMM or SODIMM formats. Registered architecture buffers each address line, allowing all four slots to be populated while keeping the memory controller load stable.

128GB capacity at CL52 1.1V

Four dual-rank modules deliver 128GB of error-correcting memory for virtualisation, database or compute workloads that need maximum DIMM density. Headroom ends when the board’s slot count or qualified vendor list is reached, so further expansion requires a different platform.

Questions about this item

Will the 1.10 V operating voltage limit how long the kit can run at DDR5 6400 under full load?

The modules are rated for 1.10 V at DDR5 6400, so the voltage is the intended operating point, not a thermal throttle trigger.

How much heat and noise should I expect from the four 32 GB RDIMMs running continuously in a populated server chassis?

The kit has no heat spreader and draws 1.1 V; thermal output and acoustics depend on your chassis airflow and fan curves, not the modules themselves.

Besides the Supermicro H13SSL-N motherboard, what other hardware must already be in place for this 288-pin RDIMM kit to function?

You need a CPU and chipset that support DDR5 6400 registered ECC memory and a BIOS configured for the correct population order.
