Exact-match server kit

This 1 TB kit contains eight 128 GB DDR5-6400 RDIMMs built to the precise 4Rx4, CL52 and 1.1 V specification that the Supermicro X14SRA-T memory controller expects. The registered ECC design lets every slot run fully populated at rated speed while correcting single-bit errors before they affect production workloads.

Registered ECC architecture

Registered buffering offloads the memory controller so all eight modules operate at full capacity without signal degradation. On-die ECC detects and corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots in continuous-operation environments.

Verify population rules

Server and motherboard memory support varies by model. Consult your system or motherboard manual for supported capacities, approved DIMM population order and installation steps before purchase to ensure the kit is recognised at its full 1 TB capacity.

Questions about this item

Will the 4Rx4 DDR5 RDIMM modules need replacement due to the lack of heat spreaders?

The modules operate at the standard 1.1V DDR5 voltage without heat spreaders; server chassis airflow is designed to maintain safe temperatures for continuous operation.

What limits sustained throughput when all eight slots are populated on the Supermicro X14SRA-T?

The registered buffer and 4Rx4 organisation let the memory controller drive every slot at the rated 6400 MT/s, so the platform's maximum supported capacity is the first ceiling reached.

How much power does the 1.1V 1TB kit draw when the server runs all day?

At the specified 1.1V the eight 128 GB modules draw only the power required for DDR5-6400 operation; registered buffering reduces electrical load on the controller compared with unbuffered alternatives.
