Exact-match DDR5 upgrade kit

This kit provides 384GB of DDR5 memory in eight 48GB registered ECC RDIMMs built for the Supermicro H13SSL-NT motherboard. It runs at 6400 MT/s with CL52 latency at 1.1V. The 2Rx8 registered design matches the board's memory controller requirements so every slot can be populated at full rated speed.

Verify platform rules before ordering

Check your system or motherboard manual for supported capacities, approved DIMM population order and installation steps. The board requires 288-pin registered RDIMMs; unbuffered UDIMMs or SODIMMs will not work. Confirm the BIOS is current enough to recognise the full 384GB configuration.

Enterprise stability under sustained load

Registered buffering offloads the memory controller so all eight modules operate reliably at full capacity continuously. ECC detects and corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots during long-running workloads. The 1.1V operation keeps power draw consistent across extended sessions.

Questions about this item

Does the kit include all eight 48 GB modules or must any be purchased separately?

The package contains the full 384 GB kit of eight 48 GB DDR5 RDIMMs, so nothing extra is required for a complete installation.

Should I choose a different capacity or speed version for the Supermicro H13SSL-NT?

This 384 GB DDR5 6400 CL52 1.10 V 2Rx8 RDIMM kit is the exact specification the H13SSL-NT memory controller expects for full-capacity operation.

Will the system actually run at 6400 MT/s once all eight slots are populated?

Registered architecture and matched 1.10 V CL52 timing let the controller drive every slot at the rated 6400 MT/s without down-clocking.
