Lenovo 32GB DDR4 2666MHz ECC DIMM

This Lenovo TruDDR4 module delivers 32GB of registered ECC memory at 2666MHz for ThinkSystem servers. The 288-pin DIMM operates at 1.20V with CL1.5 latency and PC4-21300 bandwidth. It is built for environments that require error correction and registered signal processing.

Compatibility limited to listed ThinkSystem models

This module is validated for ThinkSystem ST250, ST258, 7Y45, 7Y46 and 7Y47 servers only. Builders using other platforms, desktop boards or workstations without registered ECC support should look elsewhere. Systems needing unbuffered non-ECC memory or different pin counts cannot use this part.

Registered ECC with CL1.5 latency

The registered ECC design with CL1.5 CAS latency is the specification that determines fit. This combination provides error detection and signal buffering required by the supported ThinkSystem platforms. Verify your server requires registered ECC DDR4 at this exact latency before purchase.

Questions about this item

Will the 288-pin DDR4 DIMM fit my ThinkSystem ST250 server?

Yes, the 288-pin DDR4 DIMM is listed as compatible with the ThinkSystem ST250, ST258 and 7Y45, 7Y46, 7Y47 servers.

Do I need to configure anything in BIOS after seating the ECC registered module?

The module runs at 1.20 V with CL1.5 latency at 2666 MHz; most ThinkSystem platforms detect these settings automatically, so no manual BIOS change is usually required.

How do I know when a 32 GB TruDDR4 stick should be replaced?

Replace the module if the server logs recurring correctable ECC errors or if memory diagnostics report uncorrectable faults on that specific DIMM.
