Exact-match DDR5 upgrade

This 48GB DDR5 6400 PC5-51200 ECC RDIMM is built for the Supermicro H13SSL-NT motherboard. It delivers the precise rank, voltage and timing the board expects so the memory controller recognises full capacity at rated speed.

Registered ECC limits

Registered architecture offloads the memory controller to keep every slot stable when fully populated. ECC corrects single-bit errors on the fly to stop silent data corruption. The DDR5 interface runs at 1.1V with CL52 latency and requires the 288-pin RDIMM slot this board provides.

Replaces non-ECC or UDIMM modules

It upgrades systems running unbuffered or non-ECC memory that cannot meet server stability requirements. The jump is worth it when workloads demand full-slot population at 6400 speed with error correction. Not for builds that need consumer UDIMM or SODIMM form factors.

Questions about this item

Should I choose the 48GB 2Rx8 module or a different capacity for my Supermicro H13SSL-NT?

The 48GB 2Rx8 Registered ECC DDR5 module matches the exact rank, voltage and timing the H13SSL-NT memory controller expects, so it is recognised at full capacity and runs at its rated 6400 speed.

What does the 6400 MT/s rating mean once the module is installed in the server?

The module will operate at DDR5-6400 (PC5-51200) with CL52 latency at 1.1 V, delivering the full rated bandwidth the motherboard's memory controller supports when populated per the manual.

How does the 288-pin RDIMM interface and registered design affect real-world use?

The 288-pin Registered DDR5 form factor offloads the memory controller, allowing every slot to run fully populated at 48GB per module while ECC corrects single-bit errors on the fly.
