Capacity and target platform

This 32 GB DDR5 module is built for the Lenovo ThinkEdge SE455 V3 AI server. It provides registered ECC memory for workloads that require error correction and signal integrity in a single DIMM slot.

Thermals, noise and power draw

Operating at 1.10 V, the module draws minimal power and produces no audible noise because it has no heat spreader or moving parts. The low voltage helps keep system thermals stable during normal server operation.

Sustained load behaviour

Registered buffering and 2Rx4 organisation maintain signal quality under continuous memory traffic. ECC corrects single-bit errors on the fly, preventing data corruption during long-running AI or inference tasks.

Highlights

  • High-speed DDR5 5600 bandwidth for AI workloads
  • Registered 2Rx4 design stabilises heavy memory loads
  • Low 1.1 V voltage reduces power draw
  • Validated for Lenovo ThinkEdge SE455 V3 compatibility

Questions about this item

How do I install this 288-pin DDR5 RDIMM in the Lenovo ThinkEdge SE455 V3, and what step is commonly missed?

Power down the server, open the chassis, align the module key with the slot, and press firmly until both retention clips lock; the step often missed is confirming the BIOS recognises the full 32 GB at 5600 MT/s after the first boot.

What maintenance or replacement will this ECC RDIMM need over its service life?

No routine maintenance is required; if a correctable error count rises or the module fails, replace it with an identical 32 GB DDR5 5600 CL46 2Rx4 registered DIMM to keep ECC protection and rank balance.

What limit appears first when this memory runs under sustained load in the ThinkEdge SE455 V3?

The CL46 latency at 5600 MT/s sets the timing boundary; sustained workloads will hit this latency ceiling before the 1.1 V voltage or thermal limits become a factor.
