128GB DDR4 ECC RDIMM kit for ThinkEdge SE450

This 128GB kit contains four 32GB DDR4 3200MHz registered DIMMs built for the Lenovo ThinkEdge SE450 Edge AI server. It targets administrators who need maximum supported capacity in a validated configuration.

Registered ECC with CL22 latency

Each module runs at 1.20V with a CAS latency of 22 and a 2Rx4 organisation. The registered buffer and on-die ECC provide the signal integrity and error correction required by the platform's memory controller.

Four-module kit fills available slots

The package delivers the full 128GB in a matched set of four 288-pin RDIMMs, eliminating the need to source individual sticks and ensuring uniform timing across all channels.

Questions about this item

What does the 3200MHz speed mean once the modules are installed in a ThinkEdge SE450?

The kit runs at DDR4 3200 (PC4-25600) with CL22 latency, delivering the rated bandwidth when the server’s memory controller operates at that frequency.

How does the ECC RDIMM interface affect usable capacity and error handling?

Registered ECC modules add a buffer that stabilises the signal, allowing the full 128GB kit to be addressed while detecting and correcting single-bit errors in real time.

What physical slot and keying do these 288-pin modules need?

Each 32GB stick is a 288-pin DDR4 RDIMM requiring a standard DDR4 RDIMM socket; the kit includes four modules for the SE450’s four DIMM slots.
