1.5 TB DDR5 ECC RDIMM kit

This 1.5 TB kit contains twelve 128 GB DDR5 4800 registered DIMMs with ECC and CL40 latency. It is built for Supermicro IOT SuperServer SYS-221HE systems that require high-capacity, error-correcting memory.

Suited for Supermicro 221HE servers

The modules fit Supermicro IOT SuperServer SYS-221HE-FTNR, SYS-221HE-FTNRD and SYS-221HE-TNR platforms needing 4Rx4 registered ECC memory. Buyers with consumer motherboards or non-registered memory slots cannot use this kit.

4Rx4 registered ECC organisation

Each DIMM uses a 4Rx4 layout with on-die ECC and registered buffering at 1.1 V. This organisation decides whether the memory will initialise on the target Supermicro server platform.

Questions about this item

How do I confirm the kit is running at DDR5 4800 CL40 after installation?

Check the memory speed and timings in the server BIOS or a hardware monitoring utility; the modules should report DDR5 4800 (PC5-38400) with CL40 latency at 1.10 V.

What is included in the box and do I need any extra parts?

The package contains 12 modules of 128 GB each, totalling 1.5 TB of DDR5 ECC RDIMM memory; no additional components are required for installation.

Should I choose the 12 x 128 GB kit or a different capacity for my Supermicro SYS-221HE-FTNR?

This 12-module kit is built for the SYS-221HE-FTNR, SYS-221HE-FTNRD and SYS-221HE-TNR platforms; select it when you need the full 1.5 TB capacity across all slots.
