Exact-match server upgrade

This 1 TB kit delivers eight 128 GB DDR5 RDIMMs clocked at 4800 MT/s with CL40 timing at 1.1 V. It targets administrators expanding a Supermicro H13SSW platform that requires registered ECC modules in every populated slot.

Registered ECC for full population

The 2Rx4 registered architecture buffers address and command signals so the memory controller can drive all eight 288-pin slots at rated speed without signal degradation. ECC corrects single-bit errors on the fly, protecting data integrity in production workloads.

Low-voltage DDR5 efficiency

Operating at 1.1 V, the modules draw minimal power while maintaining 4800 MT/s throughput across a fully populated configuration. The registered design reduces electrical load on the controller, helping keep thermals stable in dense server chassis.

Questions about this item

Will the eight 128GB modules run at the rated 4800 speed without downclocking when all slots are populated?

Yes, the kit is spec-matched to the Supermicro H13SSW so the memory controller recognises the exact rank, voltage and timing and runs every slot at DDR5-4800.

How much heat do the modules produce under continuous load and do they need active airflow?

The RDIMMs operate at 1.10 V with no heat spreader; registered buffering reduces electrical load, but sustained full-capacity use still requires adequate chassis airflow to keep temperatures in spec.

Does this kit work in a standard desktop board or only in the Supermicro H13SSW?

It is built for the H13SSW's 288-pin RDIMM slots and registered ECC protocol; consumer desktop boards that accept only UDIMM memory will not recognise the modules.
