Capacity and purpose

This NEMIX RAM kit delivers 96 GB across two 48 GB DDR5 RDIMM modules built for the Lenovo ThinkEdge SE455 V3 AI server. Registered ECC operation protects data integrity in workloads that cannot tolerate silent corruption.

Speed and voltage limits

The modules run at DDR5 5600 (PC5-44800) with a CAS latency of 46 and a standard 1.10 V supply. Registered buffering and 1Rx4 organisation add latency overhead that is typical for server memory and must be matched by the platform memory controller.

Installation notes

The 288-pin DIMMs slot into the server's DDR5 RDIMM sockets without tools. Because the kit is system-specific, the main risk is mixing these registered ECC modules with unbuffered or non-ECC memory, which the platform will reject. Always follow the server manual for population order and firmware requirements.

Questions about this item

Should I choose the 96GB kit or look for a different capacity?

This kit provides 96GB total using two 48GB modules; the ThinkEdge SE455 V3 must be populated in matched pairs, so the 2x48GB configuration is the correct way to reach 96GB on this platform.

What does the 5600MHz rating mean once the modules are installed in the ThinkEdge SE455 V3?

The modules run at DDR5 5600 (PC5-44800) with CL46 latency at 1.1V; the server's memory controller will operate them at this rated speed provided the BIOS is current and the slots are filled per the platform's population rules.

How does the 288-pin RDIMM interface and ECC registration affect what I can actually use?

The 288-pin DDR5 RDIMM form factor with registered ECC and 1Rx4 organisation is required by the ThinkEdge SE455 V3; unbuffered or non-ECC DIMMs will not be recognised, and mixing ranks or voltages is not supported.
