Server memory kit for Lenovo ST650 V3

This NEMIX RAM kit delivers 128 GB of DDR5 ECC RDIMM capacity across eight 16 GB modules. It is built for the Lenovo ThinkSystem ST650 V3 tower server and targets administrators who need registered, error-correcting memory for production workloads.

Suits ST650 V3 owners adding registered ECC DIMMs

Buyers who need unbuffered UDIMMs, non-ECC modules, or a different pin count should look elsewhere. The kit is also not intended for consumer desktop boards or laptops that cannot accept registered DDR5 RDIMMs.

DDR5 5600 CL46 1.1 V registered specification

The modules run at DDR5 5600 (PC5-44800) with CL46 latency at 1.1 V in a 288-pin RDIMM form factor. This speed, voltage and registered architecture combination is the single specification that determines whether the kit matches the server's qualified memory list.

Questions about this item

How much power will the 1.1V DDR5 RDIMM kit draw when the Lenovo ThinkSystem ST650 V3 runs continuously?

Each 16GB module operates at 1.1V, so the eight-module kit runs at the standard DDR5 server voltage, keeping power draw predictable for the ST650 V3 power budget.

What must the Lenovo ThinkSystem ST650 V3 already have to accept this 288-pin registered ECC kit?

The tower server needs free DDR5 RDIMM slots that support 1Rx8 registered ECC modules and a BIOS that recognises 5600MHz PC5-44800 speeds.

Will the CL46 5600MHz modules work alongside slower DDR5 RDIMMs already installed in the ST650 V3?

The kit runs at 5600MHz CL46; if older DDR5 RDIMMs are present, the system will clock all modules to the lowest common speed and latency.
