Capacity and purpose

This 192GB kit contains six 32GB DDR5 modules built for the Lenovo ThinkEdge SE455 V3 AI Server. It targets administrators who need registered ECC memory at 5600 speed to support demanding edge workloads. The 2Rx4 organisation and 1.10V operation match the platform's validated configuration. Buyers who need a different capacity or non-ECC modules should look elsewhere.

Build and connector implications

Each module uses the standard 288-pin DDR5 RDIMM form factor without a heat spreader, so it fits the server's memory slots directly. Registered signalling and on-die ECC protect data integrity in continuous operation. The CL46 latency and PC5-44800 rating reflect the spec validated for this system. Builders who require passive cooling clearance or a different pin layout cannot use this kit.

Bundled accessories and software

The package supplies the six modules only; no additional cables, tools or software licences are included. Installation follows the server manufacturer's documented procedure and typically takes minutes. No firmware or management utilities are bundled, so administrators rely on the platform's native memory diagnostics. Users expecting a configuration utility or monitoring software will not find it here.

Questions about this item

What speed does the DDR5 5600 interface actually run at in this kit?

The modules are rated for DDR5 5600 (PC5-44800) and will operate at that data rate when the server's memory controller supports it.

Will the 288-pin RDIMM modules fit the ThinkEdge SE455 V3 memory slots?

Yes, each 32 GB module uses the standard 288-pin DDR5 RDIMM form factor required by the ThinkEdge SE455 V3.

How do I install the six 32 GB sticks correctly in the ThinkEdge SE455 V3?

Power down the server, open the chassis, and populate the DIMM slots following the population order shown in the system service guide; the most common mistake is skipping the prescribed slot sequence for registered ECC memory.
