Lenovo ThinkEdge SE450 memory kit

This 32 GB kit consists of two 16 GB DDR4 ECC RDIMM modules built for the Lenovo ThinkEdge SE450 Edge AI Server. Registered buffering and error correction protect data integrity in always-on workloads. The kit targets administrators who need to expand server capacity with validated parts.

Fits the SE450 DIMM slots directly

Each module uses the standard 288-pin DDR4 RDIMM form factor and runs at 1.2 V, so no extra power adapters or voltage tweaks are required. The dual-rank 2Rx4 organisation lets the memory controller interleave accesses across ranks. Installing the pair fills two slots and leaves remaining channels open for future expansion.

Ready-to-install matched pair

The two modules are tested together at 3200 MHz with CL22 timings to ensure consistent operation out of the box. No heat spreaders are fitted, which keeps the profile low for dense server chassis. The package contains only the memory kit itself; no additional cables, software licences or mounting hardware are included.

Questions about this item

Will the CL22 latency become the bottleneck during sustained heavy workloads on the ThinkEdge SE450?

CL22 is the rated CAS latency at 3200MHz; the memory controller on the ThinkEdge SE450 runs these modules at their specified timing, so latency stays constant under sustained load.

How much extra heat or power do the 1.2V 2Rx4 modules add when the server runs 24/7?

Each 16GB module operates at 1.20V without a heat spreader; registered ECC DDR4 at this voltage adds minimal thermal load and draws only standard DDR4 power for the configured capacity.

Does the ThinkEdge SE450 need a specific BIOS version or CPU stepping to recognise this 288-pin RDIMM kit?

The kit is validated for the Lenovo ThinkEdge SE450 Edge AI Server; install the two 288-pin RDIMMs into the supported slots and the system will detect the 32GB capacity at 3200MHz.
