Lenovo ThinkSystem DDR5 ECC RDIMM

This 32GB DDR5 4800 module delivers ECC error correction and registered signalling for Lenovo ThinkSystem servers based on AMD processors. It operates at 1.10V with CL40 latency in a single 288-pin RDIMM.

IT administrators expanding qualified Lenovo

The part matches Lenovo part number 4X77A81439 and is validated for those specific AMD-based ThinkSystem models. Builders using non-Lenovo motherboards, desktop chipsets, or systems requiring unbuffered DIMMs should select different memory.

1Rx4 registered organisation

The single-rank 1Rx4 layout with registered buffering defines electrical loading on the memory controller; confirm the server DIMM population rules accept this rank configuration before purchasing.

Domande su questo articolo

Will the 288-pin DDR5 RDIMM fit my Lenovo ThinkSystem server DIMM slots?

Yes, the 288-pin DDR5 RDIMM form factor matches Lenovo ThinkSystem server memory slots designed for registered ECC modules.

What is the correct way to seat this registered ECC module, and what step do installers often miss?

Align the notch with the slot key, press firmly until both retention clips click, and ensure the server BIOS recognises the full 32 GB capacity at 4800 MT/s.

How do I know when this ECC RDIMM should be replaced in a production server?

Monitor the system event log for corrected ECC error counts; a rising trend indicates the module should be swapped before uncorrectable errors occur.
