Capacity & Purpose

This 128GB kit contains four 32GB DDR5 modules built as ECC registered RDIMMs for SuperMicro servers. It targets administrators who need error-correcting memory to protect data integrity in storage or compute workloads.

Build Integration

Each stick uses the standard 288-pin DDR5 form factor and runs at 1.10V, so it fits compatible SuperMicro platforms without extra power hardware. The registered design buffers address and control signals, reducing electrical load on the memory controller when all four slots are populated.

Thermals & Power

Modules operate at the JEDEC base voltage of 1.1V and carry no heat spreader, relying on chassis airflow for cooling. At DDR5 4800 CL40 the power draw stays within the registered DIMM envelope, keeping acoustic impact low in typical server environments.

Questions about this item

Will the 1.1V voltage limit headroom when the kit runs 24/7 in a SuperMicro SSG-521E?

The modules operate at the standard DDR5 1.10V, so the platform's memory controller manages voltage regulation without extra headroom concerns.

How much heat do four 32GB RDIMMs produce at 4800MT/s in a fully populated chassis?

Each stick has no heat spreader and draws 1.1V at CL40; total power scales with all four ranks active under sustained load.

Does the SuperMicro X13SEDW-F motherboard need a specific BIOS revision to recognise 1Rx4 288-pin RDIMMs?

The kit is validated for the listed SuperMicro Storage SuperServer models; consult the board manual for minimum BIOS version.
