Lenovo-Compatible 32GB DDR5 RDIMM

This NEMIX RAM module delivers 32GB of DDR5 4800 registered ECC memory for Lenovo ThinkSystem servers. It operates at 1.1V with CL40 latency and a 1Rx4 organisation. The 288-pin RDIMM is built with major OEM chips and validated for Intel-based ThinkSystem platforms.

Suits ThinkSystem upgrades needing registered ECC

IT teams expanding memory in compatible Lenovo ThinkSystem servers will find this module a direct fit. Builders requiring unbuffered UDIMMs, non-ECC memory, or speeds beyond 4800MT/s cannot use this part. Systems not qualified for this specific Lenovo part number should look elsewhere.

Registered ECC RDIMM with 1Rx4 organisation

The single-rank x4 registered ECC design determines compatibility with ThinkSystem memory controllers that require registered modules. This organisation affects maximum capacity per channel and rank population rules. Verify the server memory guide for supported configurations before ordering.

Questions about this item

Does the 32GB DDR5 4800 ECC RDIMM arrive as a single stick or must I buy extra modules to reach that capacity?

The package contains one 32GB module, so the full capacity is provided in a single stick and no additional modules are required for this 32GB configuration.

How do I decide between the 1Rx4 CL40 1.1V registered DIMM and other DDR5 ECC variants?

Choose this 1Rx4 CL40 1.1V registered DIMM when your Lenovo ThinkSystem server requires a single-rank, registered ECC module at 4800 MT/s; other ranks, voltages or latencies will not match the 4X77A94004 specification.

What does the 4800 MT/s rating actually deliver once the module is installed in a compatible Lenovo server?

The module runs at 4800 MT/s (PC5-38400) with CL40 latency at 1.1V, providing the exact bandwidth and timing the ThinkSystem memory controller expects for stable ECC operation.
