OWC 16GB DDR4 3200MHz ECC RDIMM

This 16GB DDR4 3200MHz CL22 registered ECC module is built for the Lenovo ThinkSystem SE350 server. It operates at 1.2V with a 288-pin 2Rx8 layout and carries part number 3R2D42R816GB. The memory meets JEDEC and RoHS standards for reliable server operation.

Replaces Lenovo 4ZC7A15121 in ThinkSystem SE350

This module replaces Lenovo part 4ZC7A15121 directly in the ThinkSystem SE350. The upgrade is worth it when the system needs registered ECC memory with CL22 timing at DDR4 3200 speed. It cannot be mixed with unbuffered modules or used in standard desktop platforms.

Suits ThinkSystem SE350 server upgrades

This memory suits administrators upgrading or repairing a ThinkSystem SE350 with validated DDR4 3200 registered ECC capacity. Buyers who need unbuffered memory, non-ECC modules, or compatibility with desktop motherboards should look at something else.

Questions about this item

Does the 288-pin DDR4 RDIMM fit the memory slots in the ThinkSystem SE350?

Yes, the 288-pin DDR4 ECC RDIMM is built to the exact slot specification for the ThinkSystem SE350 and seats directly without adapters.

What is the correct way to seat the RDIMM and what step do installers often skip?

Align the notch with the slot key, press down firmly until both side latches click, and verify the module sits flush; the step often missed is confirming both latches are fully engaged.

When should the 16 GB ECC RDIMM be replaced in a ThinkSystem SE350?

Replace the module if the system logs correctable ECC errors that increase over time, if memory diagnostics report uncorrectable faults, or when a capacity upgrade is required.
