128GB DDR5 ECC RDIMM for SuperBlade

This 128GB DDR5 5600 module is built for Supermicro SuperBlade servers. It targets administrators who need registered ECC memory in a single high-density stick. The 1.1V JEDEC part installs directly into 288-pin slots on supported blades.

Who it suits and who it does not

Suits operators of SBI-411E-1G SBI-411E-5G SBI-421E-1T3N SBI-421E-5T3N SBI-611E-1C2N systems wanting maximum capacity per slot. Not for desktops or workstations that accept only unbuffered non-ECC DIMMs or that cannot use 4Rx4 registered modules.

Registered 4Rx4 ECC at 5600 MT/s

The module runs at PC5-44800 with CL46 latency and 4Rx4 organisation. Registered ECC operation is the single spec that decides compatibility; systems requiring unbuffered or load-reduced memory will not accept this part.

Questions about this item

Which Supermicro SuperBlade servers are confirmed to accept this 128GB DDR5 5600 ECC Registered RDIMM?

The module is validated for SuperBlade SBI-411E-1G, SBI-411E-5G, SBI-421E-1T3N, SBI-421E-5T3N and SBI-611E-1C2N.

Can this 4Rx4 registered DIMM share a channel with existing unbuffered or load-reduced ECC modules in the same SuperBlade?

No — the manufacturer states it cannot be mixed with unbuffered or ECC load-reduced memory; all DIMMs in the system must be registered ECC.

After installation, what BIOS indicator confirms the 5600 MT/s data rate and CL46 latency are active?

The memory information screen should report DDR5-5600 (PC5-44800) with a CAS latency of 46 and 1.1 V operation.
