Server DDR5 ECC RDIMM Kit

This 128GB kit contains two 64GB registered DDR5 modules rated at 4800MT/s with CL40 latency. It is built for Supermicro IOT SuperServer systems including the SYS-221HE-FTNR, SYS-221HE-FTNRD and SYS-221HE-TNR platforms.

Registered ECC With Samsung Micron Hynix Chips

The modules use major OEM DRAM from Samsung, Micron or Hynix and operate at 1.1V without a heat spreader. Registered buffering and on-die ECC protect data integrity in multi-socket server workloads.

2Rx4 Rank For Dense Configurations

Each 64GB module is organised as dual-rank 2Rx4, allowing high capacity per DIMM slot on compatible Supermicro motherboards. Builders needing single-rank modules or non-ECC memory should look elsewhere.

商品問答

Will the ECC RDIMM modules require any firmware updates or reconfiguration after installation in the Supermicro SYS-221HE series?

These registered ECC DDR5 modules are designed for direct compatibility with the listed Supermicro SuperServer systems and install without firmware changes.

What thermal limit appears first when the 2Rx4 modules run continuously at 4800 MT/s in a 1U chassis?

The DDR5 4800 RDIMMs operate at 1.1 V without heat spreaders, so case airflow must keep module temperatures within JEDEC limits during sustained loads.

How much power do the two 64 GB sticks draw and how much noise do the extra cooling fans add?

At 1.10 V the kit draws low power for 128 GB capacity, and the modules themselves are silent; any noise comes from system fans responding to chassis thermals.
