Server memory kit

This 64GB kit contains four 16GB DDR5 registered DIMMs rated at 4800 MT/s with CL40 latency. It is built for Supermicro servers and workstations that require ECC error correction and registered signal buffering.

Thermals and power

Each module operates at 1.1V and has no heat spreader, relying on chassis airflow for cooling. Registered ECC designs typically draw modest power per DIMM and generate low acoustic noise in normal server workloads.

What the kit changes

The four-module population fills four DIMM slots to deliver 64GB of registered ECC capacity for data-integrity workloads. Compatibility is validated for SuperMicro SYS-211E-FRN2T, SYS-211E-FRDN2T, X13SEM-F and X13SEM-T platforms.

Questions about this item

How do I install the four 288-Pin DDR5 RDIMM modules into the SuperMicro SYS-211E-FRN2T, and which step is most often missed?

Power down the server, open the chassis, align each module notch with the slot key, press firmly until both retention clips click, then verify all four 16 GB sticks are recognised in the BIOS before closing the case.

What maintenance or replacement will this 64 GB ECC RDIMM kit require over its service life?

No scheduled maintenance is needed; the modules have no heat spreaders and run at 1.1 V, so only a failed stick would require replacement under the lifetime warranty.

Which limit appears first when the kit runs sustained workloads at DDR5 4800 CL40?

The registered buffer and CL40 latency set the throughput ceiling, so memory bandwidth saturates before the 1.10 V thermal envelope becomes a constraint.
