Server-grade DDR5 ECC registered module

This 64GB DDR5 5600 PC5-44800 CL46 2Rx4 288-pin 1.1V ECC registered RDIMM is built for Supermicro SuperBlade SBI-611E and SBI-621E servers. It targets administrators who need JEDEC-compliant registered memory with error correction for workstation, NAS, server or network-switch workloads.

Fits validated SuperBlade platforms only

The module plugs directly into 288-pin DDR5 slots on the listed SuperBlade SBI-611E-1T2N, SBI-611E-5T2N, SBI-621E-1C3N, SBI-621E-1NE34 and SBI-621E-1NE38 systems. It cannot be mixed with unbuffered or load-reduced DIMMs and will not work in standard desktop computers.

Sustained ECC operation at 5600 MT/s

Registered buffering and on-die ECC maintain data integrity during continuous multi-threaded server tasks. The 1.1V operating voltage keeps power draw predictable under constant load, while JEDEC-standard timings ensure stable throughput without manual tuning.
