System-Specific DDR5 Kit

This NEMIX RAM kit provides 768GB of DDR5 memory across eight 96GB registered DIMMs. It is validated for the Lenovo ThinkSystem ST650 V3 tower server and targets administrators who need maximum capacity in that platform.

Capacity and Headroom

Eight 96GB modules fill the server’s DDR5 slots to deliver 768GB total, running at 5600MHz with CL46 latency. The 2Rx4 organisation and 1.1V operation suit memory-intensive workloads, while the registered design adds electrical buffering for stability at this density.

Build and Daily Use

Modules use major OEM chips from Samsung, Micron or Hynix and ship without heat spreaders, relying on the server’s directed airflow. The 288-pin RDIMM form factor matches the ST650 V3’s slots, and ECC with registered signalling protects data integrity in continuous operation.

Questions about this item

Will the eight 96GB DDR5 5600 RDIMMs run alongside any existing DDR5 4800 modules already installed in my ST650 V3?

The kit operates at DDR5 5600 (PC5-44800) with CL46 latency; mixing speeds forces the whole system to run at the slowest module speed, so all slots would drop to 4800 MT/s if slower DIMMs remain.

How can I verify the 768GB kit is recognised and running at 5600 MT/s with ECC active after installation?

Enter the UEFI setup or use a tool such as dmidecode or CPU-Z; each of the eight slots should show 96GB, 5600 MT/s, registered ECC, 2Rx4 organisation and 1.10 V.

Does the box contain only the eight 96GB RDIMMs or are any cables, brackets or cooling accessories included?

The package content lists only the 768GB (8 x 96GB) DDR5 5600MHz PC5-44800 2Rx4 1.1V 288-pin ECC RDIMM kit; no cables, brackets or heatsinks are supplied.
