1 TB DDR5 ECC RDIMM kit

This eight-module kit delivers 1 TB of DDR5 4800 registered ECC memory for Supermicro servers and workstations. It targets IT professionals who need maximum capacity per channel in mission-critical environments.

1 TB capacity with CL40 latency

The 8 x 128 GB configuration fills all slots on supported platforms, providing headroom for large virtualisation workloads and in-memory databases. Bandwidth tops out at the DDR5 4800 standard, so latency-sensitive tasks may hit limits before capacity does.

288-pin registered DIMM form factor

Modules operate at 1.1 V and require a motherboard qualified for 4Rx4 registered DDR5 ECC. No heat spreaders are fitted, so chassis airflow must handle thermal load. The kit frees procurement time by arriving pre-validated for the listed Supermicro Hyper SuperServer models.

Questions about this item

Will the 288-pin DDR5 RDIMM modules work with my existing Supermicro SYS-121H-TNR server?

Yes, the kit is validated for the SYS-121H-TNR, SYS-221H-TNR and SYS-221H-TN24R platforms.

How do I verify the ECC RDIMM kit is running at the rated 4800 speed and CL40 latency after installation?

Check the memory configuration in the system BIOS or use a hardware utility; it should report DDR5 4800 (PC5-38400) with CL40 timings.

Does the package include anything besides the eight 128 GB modules, or do I need extra parts?

The box contains only the eight 128 GB DDR5 4800 CL40 ECC RDIMM modules; no cables, brackets or additional components are supplied.
