Exact-fit DDR5-4800 RDIMM for Supermicro H13SSL-NT

This 16GB DDR5 registered ECC module is built to the precise rank, voltage and timing the Supermicro H13SSL-NT memory controller expects. It installs as a single 288-pin RDIMM and runs at the rated 4800 MT/s without manual tuning. The 1Rx8 organisation matches the board's population rules so the full capacity is recognised immediately.

ECC and registered buffering protect production

On-die ECC detects and corrects single-bit errors before they reach applications, while the registered architecture reduces electrical load on the controller. Together they allow every slot to be populated at full capacity and rated speed, preventing silent data corruption and unplanned reboots in always-on environments.

DDR5-4800 JEDEC baseline limits peak bandwidth

The module operates at the standard 4800 MT/s JEDEC speed with CL40 latency and 1.1 V. Systems that require higher data rates or lower latencies cannot exceed this specification without replacing the memory, and mixed-speed populations will downclock to the slowest installed module.

Questions about this item

Does the 1Rx8 rank layout on this DDR5 RDIMM require any specific slot population on the Supermicro H13SSL-NT?

The 1Rx8 Registered ECC module follows the board's memory-population rules; consult the Supermicro H13SSL-NT manual for the approved DIMM installation order and supported capacities before installing.

Will the CL40 latency become a bottleneck when this DDR5 4800 module runs at full speed continuously?

CL40 is the rated CAS latency for DDR5 4800 operation; the registered buffer offloads the memory controller so every slot runs at the rated speed even when fully populated.

How much heat does the 1.10V DDR5 RDIMM generate during all-day server workloads without a heat spreader?

Operating at 1.10V, the module draws minimal power; the registered architecture reduces electrical load on the controller, keeping thermals manageable in standard server airflow without a dedicated heat spreader.
