48 GB DDR5 ECC RDIMM for ThinkEdge SE455 V3

This 48 GB DDR5 5600 registered DIMM adds error-correcting memory to the Lenovo ThinkEdge SE455 V3 AI server. The single 1Rx4 module installs in an available 288-pin slot to increase capacity for virtualization, inference or data-intensive workloads.

1.1 V operation and registered design

Running at 1.10 V, the module draws minimal power while the registered buffer reduces electrical load on the memory controller. No heat spreader is fitted, so airflow through the server chassis handles cooling without added acoustic noise.

Lifetime replacement coverage included

The package contains one 48 GB DDR5 5600 CL46 ECC RDIMM backed by a lifetime replacement warranty and access to IT support staff familiar with server memory upgrades. No additional software or accessories are bundled.

Questions about this item

How do I install this 288-pin DDR5 RDIMM in the ThinkEdge SE455 V3, and what step is commonly missed?

Power down the server, open the chassis, align the module key with the slot, press firmly until both retention clips click, then verify the 48GB capacity appears in BIOS or system firmware.

What maintenance or replacement will this ECC RDIMM need over its service life?

No scheduled maintenance is required; if a correctable error count rises or the module fails, replace it with another DDR5 5600 CL46 1Rx4 ECC RDIMM of matching capacity.

What limit appears first when this 1.1 V module runs sustained workloads?

The DDR5 5600 speed and CL46 latency set the throughput ceiling; thermal throttling or voltage limits are managed by the server platform, not the module itself.
