192GB DDR5 ECC RDIMM kit for Lenovo ThinkEdge

This 192GB kit contains six 32GB DDR5 5600 registered DIMMs built with ECC and a 2Rx4 organisation. It is designed for the Lenovo ThinkEdge SE455i V3 inferencing server where registered ECC memory is required for data integrity.

Tool-free DIMM installation

Modules insert vertically into the 288-pin DDR5 slots and lock with the board ejection levers. Because they are registered DIMMs, the memory controller must support registered operation; inserting them into a consumer board that expects unbuffered DIMMs will prevent the system from posting.

Verify registered ECC support

Confirm the server motherboard lists DDR5 5600 registered ECC RDIMMs on its qualified-vendor list and that the BIOS is current enough to initialise 2Rx4 modules at 1.10V. Systems limited to unbuffered non-ECC memory cannot use this kit.

Questions about this item

How can I confirm the kit is running at 5600 MHz with CL46 latency after installation?

Check the memory speed and timing in the server BIOS or a system-information tool; the modules should report 5600 MHz and CL46 when seated correctly.

The listing shows a 192 GB kit of six 32 GB modules — are any cables, brackets or additional parts required to install them?

The box contains the six 288-pin DDR5 RDIMM modules only; no extra cables, brackets or accessories are included or needed for installation.

My ThinkEdge SE455i V3 has multiple memory configurations — why choose this 192 GB 2Rx4 registered ECC kit over other capacities?

This kit delivers the full 192 GB in six matched 2Rx4 registered ECC modules at 1.1 V, matching the server's supported DDR5 5600 specification.
