Lenovo ThinkEdge SE455i V3 DDR5 ECC RDIMM

This 32 GB DDR5 5600 module is built for the Lenovo ThinkEdge SE455i V3 inferencing server. It carries ECC and registered buffering to protect data integrity in always-on workloads. The single stick fits a 288-pin DDR5 slot and runs at 1.10 V.

Who this suits and who should look elsewhere

It suits administrators expanding the ThinkEdge SE455i V3 with validated ECC RDIMM capacity. Buyers who need non-ECC unbuffered DIMMs for a desktop platform should look elsewhere. Systems that require a different DDR generation or a different pin count cannot use this module.

Deciding specification: 2Rx4 registered ECC

The module is a 2Rx4 registered ECC DIMM rated for DDR5 5600 (PC5-44800) with CL46 latency. That combination of rank architecture, buffering and error correction is what the ThinkEdge SE455i V3 memory controller expects. Confirm the server's qualified-vendor list calls for 2Rx4 RDIMMs before ordering.

Questions about this item

Should I choose the 32GB module or a different capacity for my ThinkEdge SE455i V3?

This module provides 32GB in a single 288-pin DDR5 RDIMM. Check your server's maximum supported capacity and available slots to decide if one or multiple modules are needed.

What does the DDR5 5600 speed rating mean for actual performance in the ThinkEdge SE455i V3?

The module runs at DDR5 5600 with CL46 latency at 1.10V. Actual throughput depends on the server's memory controller and population rules; the rated speed is the maximum JEDEC standard data rate for this part.

How does the ECC RDIMM interface affect what the memory can do in this server?

The 288-pin DDR5 RDIMM uses registered buffering and ECC. This reduces electrical load on the memory bus and adds error correction, allowing the ThinkEdge SE455i V3 to support higher total capacities reliably.
