32GB DDR4 ECC RDIMM for Lenovo ThinkSystem SE350

This 32GB DDR4 3200 ECC Registered DIMM is built for the Lenovo ThinkSystem SE350 server. It delivers 32GB of capacity at CL22 latency and 1.2V operation for compatible systems. The module uses a 288-pin RDIMM form factor with 2Rx4 organisation. It replaces Lenovo part number 4ZC7A15122 in supported configurations.

Verify registered ECC support and slot availability

The SE350 must accept DDR4 3200 ECC Registered RDIMMs and have a free 288-pin DIMM slot. This memory will not work in standard desktop computers or with unbuffered modules. Mixing registered and unbuffered DIMMs is not supported. Confirm the system firmware recognises 2Rx4 registered modules before installation.

Adds 32GB per module to registered ECC

Each module adds 32GB to a registered ECC memory subsystem running at DDR4 3200. The 1.2V design matches JEDEC voltage for the platform. No heat spreader is fitted, so airflow in the server chassis handles cooling. Multiple identical modules can be populated to scale capacity within the SE350's supported limits.

Questions about this item

Does the OWC 32GB DDR4 3200 CL22 ECC RDIMM ship as a single stick or a kit, and are any extra components needed?

This is a single 32GB 288‑pin DDR4 3200 CL22 ECC Registered RDIMM. No additional parts are required; it installs directly into a compatible Lenovo ThinkSystem SE350 slot.

Should I pick the 32GB 3200 CL22 module or a different capacity for my SE350?

Choose this 32GB 2Rx4 DDR4 3200 CL22 RDIMM when your SE350 configuration calls for registered ECC memory at that speed and capacity; match identical modules per channel for best stability.

What does the 3200 MT/s rating mean once the module is running in the SE350?

The module operates at DDR4 3200 (PC4‑25600) with CL22 latency at 1.2 V, delivering the rated throughput and error‑correction the SE350 platform expects from registered ECC DIMMs.
