Exact-match server upgrade

This 32 GB DDR5 6400 MHz RDIMM is built for the Supermicro H13SSL-NT motherboard. It delivers registered ECC operation at the precise rank, voltage and timing the platform expects.

Thermals, noise and power

The module runs at 1.1 V without a heat spreader, drawing minimal power and adding no active cooling noise to the chassis. Standard server airflow handles dissipation during normal workloads.

2Rx8 registered ECC architecture

Dual-rank registered design with on-die ECC lets every populated slot run at full capacity while correcting single-bit errors in flight. Buyers needing unbuffered UDIMM or non-ECC modules cannot use this part.

Questions about this item

How is this 288-pin DDR5 RDIMM installed in the Supermicro H13SSL-NT, and what step is often missed?

Power down the server, open the chassis, and insert the module into the correct DIMM slot following the motherboard's population order; the step often missed is consulting the manual for the exact slot sequence before installation.

What maintenance or replacement will this registered ECC module need over its service life?

The module itself requires no scheduled maintenance; replacement is only necessary if a hardware fault occurs, at which point the lifetime replacement warranty covers a swap.

What limit appears first when this 1.10 V CL52 memory runs under sustained full-load conditions?

The memory controller's maximum supported capacity per channel or total system capacity is typically the first limit reached, not the module's rated 6400 MT/s speed or CAS latency.
