Server Memory Upgrade Kit

This NEMIX RAM kit supplies 576GB of DDR5 capacity across six 96GB registered DIMMs. It is built for administrators expanding a Lenovo ThinkSystem SR655 V3 AI server. Each module carries ECC and registered buffering for data integrity in enterprise workloads.

DDR5 5600 CL46 Registered ECC

The modules run at DDR5 5600 with a CAS latency of 46 and operate at 1.1V. They use a 2Rx4 organisation on 288-pin RDIMM form factor. This specification determines whether the memory matches the server's qualified vendor list and memory population rules.

Suits IT teams scaling SR655 V3 AI nodes

Organisations adding large memory footprints for AI training or virtualisation will use this kit. Buyers needing unbuffered UDIMMs, lower capacities, or memory for a different server platform should look elsewhere.

Questions about this item

What does the 5600 MT/s rating mean once the modules are installed in a Lenovo ThinkSystem SR655 V3 AI server?

The kit will run at DDR5 5600 MT/s (PC5-44800) provided the server's memory controller and BIOS support that speed; actual operating frequency follows the platform's qualified memory list.

How does the 288-pin RDIMM interface and registered design affect what the memory controller can address?

Each 288-pin DDR5 RDIMM presents a registered, 2Rx4 load to the controller, allowing higher total capacity per channel than unbuffered modules while adding one clock cycle of latency.

What physical space and power does the 6-module kit need inside the SR655 V3 AI chassis?

Six 288-pin DDR5 RDIMMs occupy six DIMM slots and draw 1.10 V each; ensure the server has six free slots and adequate airflow for the modules.
