32 GB DDR5 ECC RDIMM for Lenovo servers

This 32 GB DDR5 4800 module is built as a 288-pin registered DIMM with ECC and a 1Rx4 organisation. It targets administrators expanding Lenovo ThinkSystem platforms that require registered memory for Intel processor based servers.

Capacity and headroom at DDR5 4800

A single 32 GB stick adds substantial memory bandwidth at 4800 MT/s while operating at 1.1 V with CL40 latency. The registered buffer and ECC protect data integrity under sustained server workloads, though the module lacks a heat spreader for extended thermal headroom.

Upgrade path from lower density or non-ECC DIMMs

The part replaces smaller DDR5 RDIMMs or non-ECC modules when the platform demands registered error correction. The jump is worthwhile when the server chassis and memory controller support 1Rx4 registered DDR5 at this speed and voltage.

Questions about this item

Will this 32GB DDR5 4800 CL40 1.1V RDIMM run with existing DDR5 4800 ECC registered modules in my Lenovo ThinkSystem?

Yes, it matches DDR5 4800 PC5-38400 1.10V CL40 1Rx4 registered ECC specs; the server will clock all slots to the slowest common JEDEC timing automatically.

How do I verify the module is running at 4800 MT/s with ECC active after installation?

Check the BIOS memory info or OS tools (dmidecode, lshw, IPMI) — they should report 4800 MT/s, 1Rx4 organisation, registered ECC and 1.10V operation.

Does the package include only the 288-pin RDIMM or any extra brackets or cables?

The box contains one 32GB 288-pin DDR5 RDIMM; no brackets, cables or additional hardware are supplied.
