SuperMicro DDR5 4800 ECC RDIMM Kit

This 256GB kit contains eight 32GB DDR5 4800 registered DIMMs built for SuperMicro servers. Each module runs at 1.1V with CL40 latency and 1Rx4 organisation. ECC and register buffering protect data integrity in multi-socket platforms.

288-pin RDIMM fits SuperMicro Hyper SuperServer

The modules slot directly into compatible 121H-TNR, 221H-TNR and 221H-TN24R chassis without adapters. Registered signalling reduces electrical load on the memory controller, freeing headroom for full population across all channels. No heat spreaders are fitted, so airflow clearance follows the server vendor's guidance.

Suited for IT teams expanding SuperMicro DDR5

Buyers who need validated ECC registered memory for the listed SuperMicro models can deploy this kit with confidence. Builders requiring unbuffered UDIMMs, lower-density modules, or memory for non-SuperMicro platforms should select a different part.

Questions about this item

Will the 1.1 V operating voltage stay within spec during continuous 24-hour server workloads?

The modules are rated at 1.1 V and built with major OEM DRAM chips that are validated for sustained server operation at that voltage.

How much heat do eight 32 GB RDIMMs generate when the SuperMicro system runs at full load all day?

These RDIMMs have no heat spreader and rely on the server chassis airflow; power draw at 1.1 V is low, so thermal contribution is minimal in a properly cooled 1U or 2U enclosure.

Which SuperMicro motherboard revision and BIOS version are required before installing this 256 GB kit?

The kit is qualified for SuperMicro Hyper SuperServer SYS-121H-TNR, SYS-221H-TNR and SYS-221H-TN24R platforms; consult the system manual for the minimum BIOS revision that supports 32 GB DDR5 4800 RDIMMs.
