Lenovo ThinkSystem DDR4 ECC RDIMM

This 32 GB DDR4 3200 registered DIMM adds ECC memory capacity to compatible Lenovo ThinkSystem servers. It is built for Intel-based platforms that require registered modules with 2Rx4 organisation and 1.2 V operation. Buyers upgrading a single slot or populating multiple channels can use this module to expand system memory.

Verify DDR4 RDIMM slot availability

Confirm the server has a free 288-pin DDR4 RDIMM slot and that the motherboard accepts registered ECC memory at 3200 MT/s with CL22 timing. The platform must support 2Rx4 dual-rank modules at 1.2 V; systems limited to unbuffered UDIMMs or lower speeds will not be compatible.

Single-module kit simplifies incremental upgrades

The package contains one 32 GB stick, letting you add capacity in precise increments without buying matched pairs. No heat spreader is included, so airflow in dense server chassis remains unaffected. There is no bundled software; the module relies on the server BIOS for configuration and ECC initialisation.

Questions about this item

What comes in the box and is anything else required to install this module?

The package includes one 32 GB DDR4 3200 ECC RDIMM. No additional parts are needed for installation in a compatible Lenovo server.

Should I choose a different capacity or rank for my ThinkSystem server?

This is a single 32 GB 2Rx4 module. Select it when your configuration calls for a 32 GB registered DIMM at 3200 MT/s.

What does the 3200 MT/s rating mean once the DIMM is running in the server?

The module operates at 3200 MT/s with CL22 latency at 1.2 V, delivering PC4-25600 bandwidth in supported Lenovo ThinkSystem platforms.
