Exact-match server memory kit

This 384GB kit provides eight 48GB DDR5 RDIMM modules rated at 4800MHz with CL40 latency and 1.1V operation. It is built for the Supermicro H13SSL-NT motherboard and uses registered ECC architecture to support fully populated slots at rated speed. The 2Rx8 organization matches the board's memory controller requirements for full-capacity recognition.

Registered ECC stability at rated voltage

Registered buffering reduces electrical load on the memory controller so all eight slots run reliably at 1.1V. On-die ECC detects and corrects single-bit errors during operation, preventing silent data corruption that can crash production workloads. The modules carry no heat spreader, relying on server chassis airflow for thermal management under sustained load.

288-pin RDIMM form factor for H13SSL-NT

Each module uses the 288-pin RDIMM form factor required by the Supermicro H13SSL-NT; UDIMM or SODIMM variants will not fit or function. Builders must consult the motherboard manual for approved population order and maximum supported capacity per slot before installation. The kit frees all eight DIMM slots in a single purchase, eliminating mixed-rank configurations that can limit performance.

Questions about this item

How do I install the 8x48GB DDR5 4800 RDIMM kit in the Supermicro H13SSL-NT and which population step is most often missed?

Power down the server and unplug it. Open the chassis and locate the 288-pin DDR5 slots. Follow the motherboard manual's exact population order for 8 modules; the step most often missed is filling the correct bank sequence so the controller sees all 384GB at 4800 MT/s.

What maintenance or replacement will the 2Rx8 ECC RDIMM modules need over time?

The modules have no heat spreaders and no moving parts, so no scheduled maintenance is required. ECC corrects single-bit errors on the fly. If a module eventually fails, the lifetime replacement warranty covers a direct swap of the faulty 48GB stick.

What limit appears first when the 384GB kit runs sustained workloads at 1.1V CL40?

The registered buffer and ECC logic keep every slot stable at full 4800 MT/s throughput. The first practical ceiling is the memory controller's maximum supported capacity and rank-per-channel limit, not the modules' voltage or timing.
