384 GB DDR5 ECC RDIMM kit

This 384 GB kit contains six 64 GB DDR5 4800 modules built for SuperMicro X13SEW-TF and X13SEW-F motherboards. It targets server and workstation administrators who need registered ECC memory for mission-critical workloads.

Verify DDR5 RDIMM support and slot count

Confirm the motherboard accepts DDR5 288-pin RDIMM modules and provides at least six slots before ordering. Check that the system BIOS is current and that the platform supports 2Rx4 registered ECC at 1.1 V. Mixing with unbuffered or non-ECC DIMMs will prevent boot.

No heat spreader, standard server form factor

Modules ship without heat spreaders, matching typical server chassis airflow designs. The 288-pin RDIMM connectors seat directly into registered DIMM slots; ensure the retention levers engage fully. Registered buffering adds a clock cycle, so verify the platform expects registered memory for stable operation.
