System-specific DDR5 RDIMM for Lenovo ST650 V3

This 16 GB registered ECC module is built for the Lenovo ThinkSystem ST650 V3 tower server. It targets administrators who need validated, single-rank memory to expand or repair that platform without compatibility guesswork.

Registered ECC with CL46 latency at 5600 MT/s

The decisive spec is the registered ECC design combined with a CAS latency of 46 at the DDR5 5600 (PC5-44800) data rate. That combination ensures error correction and signal integrity the ST650 V3 memory controller expects; non-registered or non-ECC alternatives will not function in this system.

Single 16 GB rank at 1.1 V

One 1Rx8 rank delivers 16 GB of capacity, suitable for moderate virtualisation workloads or database buffers. The module draws 1.1 V and has no heat spreader, so dense configurations rely on server airflow; buyers needing more than 16 GB per slot or lower-latency timings must look elsewhere.

Questions about this item

What does the 5600 MHz rating mean once this module is installed in a ThinkSystem ST650 V3?

The module will run at up to 5600 MT/s, delivering PC5-44800 bandwidth, provided the server's memory controller and BIOS support that speed.

How does the 288-pin DDR5 RDIMM interface affect usable speed in this server?

The 288-pin DDR5 RDIMM form factor carries the registered signal required by the ST650 V3; actual throughput is capped by the platform's maximum supported memory speed.

What physical slot and clearance does this 288-pin RDIMM need in the ST650 V3?

It fits a standard DDR5 RDIMM slot; the module has no heat spreader, so it clears most tower-server DIMM cages without extra height allowance.
