Server Memory Upgrade

This OWC module is a 128 GB DDR5 ECC Registered DIMM built for Supermicro SuperBlade SBI-621E-1T3N and SBI-621E-5T3N systems. It targets administrators who need to expand memory capacity in compatible blade servers and workstations. The module uses a 288-pin form factor and operates at 1.1 V. It is not suitable for standard desktop computers or consumer motherboards.

Registered ECC Architecture

The single specification that determines fit is the registered ECC design with a 4Rx4 organisation. This memory cannot be mixed with unbuffered or load-reduced modules and requires a platform that supports registered DDR5 DIMMs. JEDEC-standard PC5-44800 timing at CL46 ensures compatibility with the qualified SuperBlade systems. Verify your server accepts registered ECC DDR5 before purchase.

Capacity and Headroom

A single 128 GB stick provides substantial memory headroom for virtualisation, database workloads and multi-tenant services on supported blades. The 5600 MT/s data rate delivers bandwidth for demanding server applications. Capacity scales by populating additional slots with identical modules. Systems limited to lower memory speeds or unbuffered memory will not benefit from this module.

Questions about this item

What does the 5600 MT/s speed mean once the module is installed in a SuperBlade server?

The module runs at the JEDEC-standard 5600 MT/s DDR5 data rate, delivering PC5-44800 bandwidth when the platform memory controller is configured for that speed.

How does the 288-pin DDR5 ECC registered interface affect usable capacity and mixing rules?

The 288-pin registered DIMM presents a 4Rx4 organisation with on-die ECC; it cannot be mixed with unbuffered or load-reduced modules in the same system.

What physical slot and clearance does the 128 GB stick need in a SuperBlade SBI-621E chassis?

It fits a standard 288-pin DDR5 RDIMM socket and has no heat spreader, so it clears the tight blade-server DIMM spacing without extra height.
