32 GB DDR4 ECC RDIMM for ThinkEdge SE450

This 32 GB DDR4 registered DIMM adds error-correcting memory to the Lenovo ThinkEdge SE450 Edge AI server. It operates at 3200 MHz with a CAS latency of 22 and runs at 1.2 V. The module uses a 2Rx4 organisation across 288 pins.

Sustained load behaviour with registered ECC

The registered buffer reduces electrical load on the server memory controller during continuous operation. ECC detects and corrects single-bit errors to maintain data integrity under long-running workloads. The 1.2 V supply keeps power draw stable during extended use.

DDR4 RDIMM capacity and speed limits

DDR4 RDIMM topology caps per-module density at 32 GB for this speed grade. The PC4-25600 rating defines the maximum sustained transfer rate at 3200 MT/s. Mixing ranks or speeds beyond the platform specification will prevent the server from posting.

Questions about this item

How much power does the 1.2 V DDR4 RDIMM draw when the ThinkEdge SE450 runs 24/7?

Each 32 GB module operates at 1.2 V, the standard DDR4 server voltage, so power draw stays within normal registered DIMM limits for continuous edge workloads.

What must the ThinkEdge SE450 already have to accept this 288-pin ECC RDIMM?

The server needs an available DDR4 RDIMM slot that supports 3200 MHz ECC registered memory and a BIOS that recognises 2Rx4 32 GB modules.

Will this CL22 3200 MHz stick work alongside slower DDR4 DIMMs already in the SE450?

Yes — the module runs at DDR4 3200 CL22, and the system will clock all installed DIMMs to the lowest common speed and latency.
