OWC 64GB DDR4 3200MHz CL22 ECC RDIMM SE350

64 GB DDR4 ECC RDIMM for Lenovo ThinkSystem SE350

This 64 GB DDR4 3200 MHz CL22 registered DIMM is built for the Lenovo ThinkSystem SE350 server. It delivers error-correcting code memory with 2Rx4 organisation and operates at 1.2 V. The module is intended for administrators who need to expand or repair memory in that specific platform.

Sustained-load behaviour with ECC registered design

Registered buffering reduces electrical load on the memory controller during continuous operation. ECC detects and corrects single-bit errors to maintain data integrity under long-running workloads. The CL22 latency at 3200 MHz provides stable throughput for virtualisation and database tasks. JEDEC compliance ensures consistent timing across all populated slots.

Verify slot count and existing DIMM population

Confirm the SE350 has an available 288-pin DDR4 slot before ordering. Registered ECC modules cannot be mixed with unbuffered memory in the same system. All installed DIMMs should match capacity, speed and manufacturer for optimal performance. This module replaces Lenovo part number 4ZC7A15124.
