2TB DDR5-4800 ECC RDIMM kit

This 2TB kit contains sixteen 128GB registered DDR5 modules rated at 4800 MT/s with CL40 latency and 1.1V operation. It is built for SuperMicro IOT SuperServer SYS-221HE-FTNR, SYS-221HE-FTNRD and SYS-221HE-TNR platforms that require ECC RDIMM memory.

Suited for administrators expanding compatible

Buyers needing unbuffered UDIMM modules, non-ECC memory, lower capacities or different form factors should look elsewhere. Systems that do not support 4Rx4 registered DDR5 DIMMs cannot use this kit.

Fits 288-pin DDR5 RDIMM slots in qualified

The registered design and on-die ECC offload error correction from the CPU, freeing processor cycles for workloads. Each module operates at the standard 1.1V DDR5 voltage, simplifying power planning for dense 16-DIMM configurations.

Questions about this item

Does the Supermicro SYS-221HE server need any specific firmware or BIOS version before installing the 16 DDR5 4800 RDIMMs?

The modules are validated for the listed Supermicro IOT SuperServer models; consult the server manual for any required BIOS revision before populating all 16 slots.

Can the 4Rx4 registered ECC modules run alongside existing DDR5 RDIMMs of a different speed or rank?

Mixing ranks or speeds is not recommended; the server will operate at the lowest common speed and may require specific slot population rules from the vendor.

How can I confirm the kit is running at 4800 MT/s with CL40 timings after installation?

Check the BIOS memory information page or use a tool such as dmidecode to verify the reported speed of 4800 MT/s and CAS latency of 40.
