Target system and capacity

This 1 TB memory kit contains eight 128 GB DDR5 RDIMM modules built for the SuperMicro IOT SuperServer SYS-221HE series. The registered ECC design targets enterprise workloads that demand data integrity and maximum density per DIMM slot.

Registered ECC and chip sourcing

Registered buffering and on-die ECC protect against soft errors in mission-critical deployments. Modules draw from major OEM Samsung, Micron or Hynix die to meet the validated configuration for the qualified SuperMicro platforms.

DDR5 4800 CL40 at 1.1 V

The kit runs at DDR5 4800 (PC5-38400) with CL40 latency and 1.10 V operation. This speed and voltage combination is the single specification that determines compatibility with the supported SuperMicro 221HE motherboards.

Questions sur cet article

Do the 128GB modules need any periodic maintenance or replacement once installed?

No, the DDR5 ECC RDIMM modules have no moving parts and require no scheduled maintenance or replacement under normal server operation.

Will the CL40 latency or 1.1V voltage become the limiting factor during sustained workloads?

The CL40 timing and 1.1V operating voltage are fixed JEDEC specifications; sustained throughput is limited by the DDR5 4800 transfer rate, not by latency or voltage headroom.

How much heat and power do the eight 4Rx4 modules generate when the server runs continuously?

Each 128GB module operates at 1.1V within standard DDR5 4800 power envelopes; the registered 4Rx4 design adds minimal overhead, so total heat output matches typical 1TB RDIMM configurations.
