Server-grade DDR5 kit

This 2 TB memory kit delivers sixteen 128 GB DDR5-4800 registered ECC RDIMMs for ThinkMate Supermicro SuperServer 421GE-TNRT platforms. The modules operate at 1.10 V with CL40 latency and a 4Rx4 organisation. IT teams can populate all slots in a single upgrade cycle.

Capacity and headroom

The 2 TB total capacity supports large in-memory databases, virtualisation clusters and high-throughput analytics workloads. Registered buffering and on-die ECC protect data integrity under sustained load. The kit reaches its limit when the platform’s memory controller or socket count restricts further expansion.

Build integration

Each 288-pin RDIMM fits the server’s DDR5 slots without a heat spreader, leaving clearance for dense CPU coolers. Registered signalling reduces electrical load on the memory controller, freeing headroom for additional system stability. Compatibility is validated for the specified ThinkMate SuperServer models only.

Questions about this item

Will the 4800 MT/s DDR5 RDIMMs run at their rated speed when mixed with existing DDR5 4800 modules in the Supermicro 421GE-TNRT?

Yes, the 16 modules are DDR5 4800 PC5-38400 CL40 1.1V registered ECC RDIMMs, matching the server's native memory specification.

How can I confirm the 2 TB kit is recognised correctly after installation?

The system BIOS or OS should report 16 x 128 GB DDR5 4800 registered ECC RDIMMs totalling 2 TB with CL40 timings at 1.1 V.

Does the MR38400-744K16 package include only the 16 RDIMMs or any extra items such as heat spreaders?

The package contains the 16 x 128 GB DDR5 4800 CL40 1.1 V 288-pin ECC registered RDIMMs; no heat spreaders or other accessories are included.
