512 GB DDR5 ECC RDIMM kit

This NEMIX RAM kit provides 512 GB of DDR5 memory across four 128 GB modules. Each module runs at 4800 MT/s with CL40 latency at 1.10 V. The 288-pin registered DIMMs include on-die ECC and a 4Rx4 organisation for data integrity in demanding workloads.

For Supermicro X13SEM platforms

The kit is validated for Supermicro SYS-211E-FRN2T, SYS-211E-FRDN2T, X13SEM-F and X13SEM-TF systems. Builders using other motherboards or consumer chipsets should verify qualified vendor lists before purchasing, as registered ECC DIMMs will not function in unbuffered slots.

Registered 4Rx4 ECC at 1.10 V

The combination of registered signalling, 4Rx4 density and on-die ECC at 1.10 V determines compatibility. Only systems that explicitly support DDR5 RDIMMs with this rank structure and voltage will POST and operate correctly with this kit.

Questions about this item

Will the 288-pin DDR5 RDIMM modules fit the DIMM slots on a SuperMicro SYS-211E-FRN2T server?

Yes, the kit is built as a 288-pin DDR5 RDIMM package specifically for SuperMicro SYS-211E-FRN2T, SYS-211E-FRDN2T, X13SEM-F and X13SEM-TF platforms.

What is the correct sequence for populating the four 128 GB modules on a dual-processor SuperMicro board?

Install one module per channel following the motherboard manual slot order — typically CPU0 channel A then B, then CPU1 channel A then B — and seat each RDIMM until the ejectors click.

How long do the Samsung, Micron or Hynix DRAM chips on these registered ECC RDIMMs last under continuous server workloads?

The major OEM DRAM chips are rated for continuous operation; ECC corrects single-bit errors and the registered buffer reduces electrical load, so modules typically run for the server's service life without replacement.
