Server-ready DDR5 ECC kit

This 128GB kit contains two 64GB DDR5-4800 registered DIMMs built for the Supermicro H13SSL-NT motherboard. Each module runs at 1.1V with CL40 latency and a 2Rx4 organisation. The registered design lets every slot operate fully populated at the rated speed.

Verified Supermicro fitment

The 288-pin RDIMM form factor matches the board's physical and electrical requirements exactly. Rank, voltage and timing are pre-validated so the memory controller recognises the full capacity without manual tuning. Consult the motherboard manual for approved population order before installation.

Enterprise stability daily

Registered buffering reduces electrical load on the memory controller while ECC corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots. Major OEM DRAM from Samsung, Micron or Hynix underpins consistent operation in 24/7 production environments.

Questions about this item

Will the 2Rx4 registered DIMMs need any firmware updates or periodic re-seating after installation?

No firmware updates or scheduled re-seating are required; the modules are validated for the Supermicro H13SSL-NT and run at the rated DDR5 4800 speed once seated.

What is the first limit reached when the kit runs at full load continuously?

The memory controller's maximum supported capacity and population rules define the ceiling; this 128 GB kit matches the board's qualified configuration.

How much heat and power does the 1.1 V DDR5 kit produce during all-day operation?

Operating at 1.1 V with no heat spreader, the registered ECC modules draw minimal power and rely on the server's standard airflow for cooling.
