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.

Soalan tentang produk ini

How much power does the 1.2V DDR4 3200 module draw when the SE350 runs continuously?

The module operates at 1.2V, the standard DDR4 voltage, so power draw stays within JEDEC limits for registered ECC DIMMs during all-day server workloads.

What must the ThinkSystem SE350 already have to accept this 288-pin RDIMM?

The SE350 needs free DDR4 RDIMM slots that support ECC registered memory; the system cannot use unbuffered DIMMs alongside this module.

Can I keep the existing Lenovo 4ZC7A15124 sticks and add this 64GB 2Rx4 kit?

Yes — this OWC DIMM replaces the 4ZC7A15124 part number, so it can be installed alongside identical-capacity registered ECC modules for matched performance.
