System-Specific DDR5 Server Memory Kit

This NEMIX RAM kit delivers 256GB across four 64GB registered ECC RDIMMs built for the Supermicro X14SBM-TF platform. The modules run at 6400MHz with CL52 latency at 1.10V using 4Rx4 organisation. They are validated for compatibility with the target motherboard.

For IT teams scaling memory on qualified

The kit suits administrators who need maximum registered ECC capacity on this specific board. It is not for desktop builders, consumer motherboards, or systems that require unbuffered DIMMs or lower-density modules. Buyers without a Supermicro X14SBM-TF should verify their platform before ordering.

256GB registered ECC capacity for heavy server

Four 64GB ranks provide ample headroom for virtualisation, databases and memory-intensive AI tasks on the supported platform. The 6400MHz CL52 specification delivers the rated throughput for the qualified system. Workloads exceeding 256GB or requiring higher frequencies will need a different configuration.

Questions about this item

Do I need a Supermicro X14SBM-TF motherboard to use this 256GB DDR5 6400MHz ECC RDIMM kit?

Yes, this 4Rx4 registered kit is validated for the Supermicro X14SBM-TF and requires a DDR5-capable server board with 288-pin RDIMM slots.

Will the four 64GB modules run at 6400MHz if the board only supports a lower DDR5 speed?

The kit is rated PC5-51200 at CL52 1.10V; the motherboard will negotiate the highest common speed supported by its memory controller.

How can I confirm the 256GB kit is operating at 6400MHz with ECC active after installation?

Check the BIOS memory information or use a tool such as dmidecode to verify speed, 4Rx4 organisation and ECC status.
