2 TB DDR5 4800 Registered ECC Kit

This 2 TB kit contains sixteen 128 GB DDR5 4800 modules built to PC5-38400 specification. Each module is a 4Rx4 registered ECC RDIMM running at 1.1 V with CL40 latency. The kit is validated for Supermicro Hyper SuperServer SYS-121H-TNR, SYS-221H-TNR and SYS-221H-TN24R platforms.

Suits administrators expanding memory

Builders who need unbuffered UDIMMs, non-ECC modules, lower-capacity DIMMs or a different pin count cannot use this kit. Systems that do not support registered ECC DDR5 or that require a different rank configuration should look elsewhere.

4Rx4 registered ECC RDIMM at 1.1 V

The 4Rx4 organisation and registered ECC design are the decisive factors for compatibility. Only motherboards that accept 288-pin DDR5 RDIMMs with this rank structure and voltage will operate correctly with these modules.

Questions about this item

Does the 1.10 V operating voltage limit thermal headroom during sustained all-core workloads?

The modules run at 1.10 V with no heat spreader; thermal margin depends on chassis airflow and DIMM spacing in the Supermicro server.

How much acoustic noise do the 16 modules add when the system runs continuously?

The RDIMMs themselves are silent; any noise comes from server fans reacting to the 2 TB memory load under sustained traffic.

Which Supermicro motherboard revision must already be installed for this 288-pin DDR5 kit to function?

The kit is validated for SuperMicro Hyper SuperServer SYS-121H-TNR, SYS-221H-TNR and SYS-221H-TN24R platforms.
