  • Exact 288-pin RDIMM form factor verified for Supermicro H13SSL-N ensures physical and electrical compatibility

256 GB DDR5-5600 ECC RDIMM kit for Supermicro

This 256 GB kit contains two 128 GB DDR5-5600 registered ECC modules built to the exact rank, voltage and timing the Supermicro H13SSL-N memory controller expects. It targets administrators who need full-capacity population on that specific server board without compatibility guesswork.

Registered ECC architecture and 288-pin form factor

The registered design offloads the memory controller so every slot runs fully populated at the rated 5600 MT/s, while on-die ECC corrects single-bit errors before they reach production workloads. The 288-pin RDIMM form factor matches the board's required slot type and population rules, and the modules operate at 1.1 V with CL46 latency.

Replaces partial or mismatched DDR5 populations

Install this kit when the server currently runs fewer modules, mixed ranks or slower speeds that limit total capacity or introduce stability risk. The jump is worth it when the workload demands the full 256 GB at the board's native DDR5-5600 rate with registered ECC integrity.

Questions about this item

What DDR5 speed and PC5 rating does this 256GB kit run at?

This kit operates at DDR5 5600 with a PC5-44800 rating, so the memory controller sees the full 5600 MT/s data rate when all slots are populated.

What physical slot and form factor does the Supermicro H13SSL-N require for these modules?

The board takes 288-pin DDR5 RDIMMs; each 128GB module in this kit matches that exact registered form factor and will not fit UDIMM or SODIMM slots.

In what order should the two 128GB RDIMMs be installed on the H13SSL-N?

Consult the motherboard manual for the approved DIMM population sequence; the board's memory rules dictate which channels fill first for full 256GB recognition.
