Lenovo SR685a V3 ECC RDIMM

This 32GB DDR5 module is built for the Lenovo ThinkSystem SR685a V3 rack server. It delivers registered ECC memory that enterprise workloads require for data integrity. IT teams choose it when expanding capacity in supported Lenovo platforms.

Registered 288-pin DDR5 at 1.1V

The stick uses a 1Rx4 organisation and runs at 5600MT/s with CL46 latency. Registered buffering reduces electrical load on the memory controller, while the 1.1V operation matches the DDR5 baseline for server boards. No heat spreader is fitted, so airflow in the chassis handles cooling.

Replaces lower-capacity or non-ECC DDR5 RDIMMs

The upgrade is worth it when the server needs more registered ECC memory for virtualisation, databases or large datasets. It is not for systems that accept only unbuffered DIMMs or that require a different DDR generation.

Questions about this item

What DDR5 speed and CAS latency does this 32 GB module run at?

The module operates at DDR5 5600 with a CAS latency of CL46, delivering PC5-44800 bandwidth.

What physical slot and pin count does this RDIMM require?

It uses a standard 288-pin DDR5 RDIMM slot; the module is single-rank 1Rx4 with no heat spreader.

How is the module installed in the Lenovo ThinkSystem SR685a V3 and what step is often missed?

Power down the server, open the chassis, align the notch on the 288-pin edge connector with the slot key, press firmly until the retention clips lock, then verify the new capacity in BIOS.
