Lenovo ThinkEdge SE455 V3 64GB DDR5 RDIMM

This 64GB DDR5 5600 CL46 registered ECC module is built for the Lenovo ThinkEdge SE455 V3 AI server. It targets administrators who need to expand memory capacity on that specific platform. The 2Rx4 organisation and 1.1V operation match the server's qualified memory list. Buyers with other DDR5 systems or non-ECC boards cannot use this module.

ECC registration and 2Rx4 rank

The registered buffer and on-die ECC protect data integrity in continuous AI and inference workloads. The 2Rx4 rank layout allows higher density per channel without exceeding the platform's load limits. No heat spreader is included, so airflow in the chassis must handle thermal management. The package contains a single 64GB stick; no extra cables, software or brackets are supplied.

Tool-less DIMM slot insertion

Installation follows the standard 288-pin DDR5 RDIMM procedure: open the retaining clips, align the notch, press until the clips click. The keyed notch prevents backwards insertion. Common issues arise when mixing ranks or speeds across channels, so populate identical slots per the server manual. Firmware must recognise the 5600 MT/s JEDEC profile; older BIOS revisions may default to a lower speed.

Questions sur cet article

Will the 2Rx4 288-pin DDR5 module need replacement if a rank fails?

The 2Rx4 organisation means two ranks share one module; if a rank fails the entire 64GB stick must be swapped.

What limits sustained throughput at 5600 MT/s CL46?

The CAS latency of 46 cycles at 5600 MT/s sets the timing ceiling for continuous read and write streams.

How much heat and power does the 1.1 V registered ECC DIMM produce under all-day load?

At 1.10 V the module draws minimal power and runs without a heat spreader, so thermal output stays low during extended operation.
