Exact-match DDR5 server upgrade

This 16 GB DDR5-6400 module is built for the Supermicro H13SSL-N motherboard. It delivers the precise rank, voltage, and timing the board's memory controller expects for full-capacity recognition.

Registered ECC limits and population rules

Registered architecture offloads the controller so every slot can run fully populated at rated speed. ECC corrects single-bit errors on the fly to stop silent data corruption. The motherboard manual defines supported capacities and required DIMM population order.

288-pin RDIMM form factor without spreader

The 288-pin Registered DIMM fits only boards wired for DDR5 RDIMMs, not UDIMM or SODIMM slots. No heat spreader is fitted, so airflow in the chassis must handle thermal dissipation. Buyers needing unbuffered memory or desktop form factors cannot use this module.

Questions about this item

Should I pick the 16 GB DDR5-6400 CL52 1Rx8 ECC RDIMM or a different capacity?

This module is a single 16 GB stick rated at DDR5-6400 with CL52 latency, 1.1 V operation and 1Rx8 registered ECC. Choose it when your Supermicro H13SSL-N requires exactly that rank, voltage and timing; add more identical sticks only if the board's population rules allow additional DIMMs per channel.

What does the 6400 MT/s rating actually deliver in the Supermicro H13SSL-N?

The board's memory controller will run this RDIMM at its rated 6400 MT/s (PC5-51200) with CL52 timings at 1.1 V, provided the BIOS is current and the DIMM is installed in a supported slot. Registered buffering lets every populated slot operate at that speed without down-clocking.

How does the 288-pin RDIMM interface limit performance on this platform?

The 288-pin registered DDR5 interface matches the H13SSL-N's DIMM slots exactly; the registered buffer removes electrical load from the memory controller so full population at 6400 MT/s is possible, while ECC corrects single-bit errors without reducing throughput.
