Compatible Lenovo ThinkSystem Upgrade

This NEMIX RAM module delivers 16GB of DDR4 3200 ECC registered memory built for Lenovo ThinkSystem servers. It carries part number 4X77A85855 and runs at 1.2V with CL22 latency. The 2Rx8 organisation and 288-pin RDIMM form factor match the platform’s qualified configuration.

Suited For Intel-Based ThinkSystem Servers

Administrators expanding memory in compatible Intel-powered ThinkSystem platforms will find this module validated for those workloads. It is not intended for consumer desktops, laptops or non-ECC workstations that require unbuffered DIMMs. Builders needing higher densities or different ranks should verify the system’s qualified vendor list before purchasing.

Registered ECC RDIMM With 2Rx8 Organisation

The single decisive specification is the registered ECC RDIMM layout with 2Rx8 rank structure. Only systems that explicitly support this registered topology and rank configuration will POST and operate correctly. Confirm the server’s memory qualification document lists this exact organisation before ordering.

Questions about this item

Does the 288-pin DDR4 RDIMM fit a standard server DIMM slot?

Yes, the module uses the 288-pin DDR4 RDIMM form factor that matches standard registered DIMM slots in compatible Lenovo ThinkSystem servers.

What is the correct order for installing this 2Rx8 registered module alongside existing memory?

Follow the server's population rules: fill the lowest-numbered channel slots first and keep identical rank and speed modules together per channel.

Will the ECC registered design require any firmware updates or battery-backed maintenance over time?

No ongoing firmware or battery maintenance is needed; the module operates at 1.20 V with on-die ECC and registered buffering for the life of the server.
