SuperMicro X13SET Compatible Memory

This 256 GB kit contains two 128 GB DDR5 registered DIMMs built for SuperMicro X13SET-G and X13SET-GC motherboards. It targets IT professionals and system integrators who need ECC RDIMM capacity for enterprise servers and workstations.

Verify DDR5 RDIMM support and slot population

Confirm that your SuperMicro X13SET platform accepts 4Rx4 registered modules at 4800 MT/s and that the BIOS revision in use supports the full 256 GB configuration before ordering.

Low-voltage operation at 1.1 V

The modules run at 1.10 V without heat spreaders, relying on server chassis airflow for cooling. Registered buffering and ECC add minimal latency while maintaining signal integrity under sustained load.
