Server memory for Lenovo systems

This 32GB DDR4-2666 registered ECC RDIMM is built to match Lenovo part number 01DE974. It runs at 1.2V on a 288-pin DDR4 interface with a 2Rx4 rank layout and major-brand chips. The module is designed for servers that require registered error-correcting memory.

Suited for administrators expanding compatible

It fits workloads that benefit from maximum installed capacity and registered buffering. Builders needing unbuffered UDIMMs, load-reduced LRDIMMs, different speeds, capacities other than 32GB, or non-ECC memory should select a different module.

Registered ECC with 2Rx4 organisation

The registered buffer and ECC function together with the dual-rank x4 configuration to meet the platform's signal-integrity and error-detection requirements. If the server calls for a different rank structure or unbuffered operation this part will not work.

Questions about this item

My server has 288-pin DDR4 slots — will this 2Rx4 ECC registered module fit and run at DDR4-2666?

Yes — the module uses the standard 288-pin DDR4 form factor and is rated for DDR4-2666 (PC4-21300) at 1.2 V, so it installs directly into any compatible registered-DIMM slot.

I already have 2Rx4 registered ECC DIMMs at 1.2 V — can I mix this 32 GB stick with them?

Mixing is possible when the existing DIMMs share the same DDR4-2666 speed, 1.2 V voltage, ECC registered design and 2Rx4 organisation; the system will then run all modules at the common supported frequency.

After installation, how can I confirm the module is recognised as 32 GB ECC registered at DDR4-2666?

Check the BIOS/UEFI memory information or run a tool such as dmidecode — it should report 32 GB, DDR4-2666, 1.2 V, ECC registered, 2Rx4 organisation and the Lenovo 01DE974 part number.
