128GB DDR5 ECC RDIMM Kit

This 128GB kit contains two 64GB DDR5 5600MHz ECC registered DIMMs built for the Lenovo ThinkEdge SE455i V3 inferencing server. It targets administrators who need maximum registered capacity in that specific platform.

DDR5 5600 Registered Limits

The modules run at 5600MHz with CL46 latency and 1.1V voltage using a 2Rx4 organisation. Registered buffering and ECC are mandatory for the platform; unbuffered or non-ECC DIMMs will not function in this server.

288-Pin Installation Notes

Each 288-pin DIMM seats vertically in the server’s memory slots without a heat spreader. Alignment keys prevent backward insertion; the only common error is leaving a module partially unlatched, which causes a post failure.

Questions about this item

Should I pick this 128 GB kit or a smaller capacity for the ThinkEdge SE455i V3?

The kit supplies 128 GB as two 64 GB modules, matching the server’s supported DDR5 5600 speed and registered ECC design for full capacity utilisation.

What does the 5600 MHz rating deliver once installed in the ThinkEdge SE455i V3?

The modules run at DDR5 5600 (PC5-44800) with CL46 latency at 1.1 V, providing the rated bandwidth and error correction the inferencing server expects.

How does the 288-pin RDIMM interface limit performance in this server?

The 288-pin DDR5 RDIMM form factor with registered signalling and 2Rx4 organisation is the native interface for the ThinkEdge SE455i V3, so the memory controller operates at the full 5600 MT/s without downshifting.
