ThinkEdge SE450 ECC RDIMM

This 128GB DDR4 3200 CL22 4Rx4 ECC RDIMM is built for the Lenovo ThinkEdge SE450 Edge AI Server. It delivers registered error-correcting memory in a single 288-pin module running at 1.20V.

Suited for capacity-limited slots.

The single 128GB stick fills one slot, ideal when the ThinkEdge SE450 has limited DIMM positions. Builds that need matched pairs for dual-channel bandwidth or lower-latency CL timings should look at something else.

Module only — no cables, software or heat spreader

The package contains the 288-pin RDIMM alone. No heat spreader is included, so airflow in the SE450 chassis handles cooling. No configuration utility or driver disc is bundled.

Questions about this item

What Lenovo server must I already own for this 128GB DDR4 3200 CL22 4Rx4 ECC RDIMM to work?

The module is validated for the Lenovo ThinkEdge SE450 Edge AI Server; install it in an available 288-pin DDR4 RDIMM slot on that platform.

How does this 1.2V 4Rx4 registered DDR4 behave when mixed with older DDR4 RDIMMs already in the ThinkEdge SE450?

The server will run all populated channels at the lowest common speed and latency; the new stick will down-clock to match existing modules if they are slower than 3200 MT/s.

How can I confirm the 128GB PC4-25600 ECC RDIMM is operating correctly after installation?

Enter the ThinkEdge SE450 BIOS or UEFI and verify the memory shows 128GB capacity, 3200 MT/s speed, ECC enabled and the registered rank configuration detected.
