256GB DDR5 ECC RDIMM kit for Supermicro servers

This 256GB kit contains four 64GB DDR5 4800 registered DIMMs with ECC and a CL40 latency. It is built for Supermicro systems such as the SYS-211E-FRN2T, SYS-211E-FRDN2T, X13SEM-F and X13SEM-TF. The modules run at 1.1V and use a 2Rx4 organisation for high-density server workloads.

Upgrade from smaller DDR5 kits or non-ECC memory

Replacing a lower-capacity kit or unbuffered modules with this registered ECC kit adds the error correction and signal integrity required by the listed Supermicro platforms. The jump is worth it when the workload demands maximum registered DIMM capacity per channel and the motherboard qualification list includes this part number.

Straightforward DIMM installation

The 288-pin modules seat in standard DDR5 RDIMM slots and the kit is validated for the named Supermicro servers. Problems usually arise when the BIOS is not updated to the revision that supports 64GB dual-rank densities or when the DIMM population order does not follow the system manual for the X13SEM-F or X13SEM-TF boards.

Questions about this item

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

Yes, the 288-pin DDR5 RDIMM form factor matches the memory slots on the SuperMicro SYS-211E-FRN2T and related X13SEM-F and X13SEM-TF motherboards.

What is the correct order for populating the four 64GB modules during installation?

Install the four 64GB modules following the motherboard manual's channel population sequence, typically filling one DIMM per channel first to enable multi-channel operation.

When should the registered ECC RDIMM kit be replaced or re-qualified?

Replace or re-qualify the kit if the server reports uncorrectable ECC errors, fails memory diagnostics under load, or when upgrading to a platform that requires a different DDR generation or voltage.
