System-specific DDR5 ECC UDIMM for Lenovo tower

This NEMIX RAM module delivers 16 GB of DDR5 5600 ECC unbuffered memory in a single 288-pin UDIMM. It is built for the Lenovo ThinkSystem ST50 V3 tower server and uses major OEM chips from Samsung Micron or Hynix. The stick runs at CL46 latency with a 1.1 V operating voltage.

Verify DDR5 ECC UDIMM support and slot availability

Confirm the motherboard accepts DDR5 ECC unbuffered UDIMMs at 5600 MT/s and has a free 288-pin slot before ordering. The module is a 1Rx8 configuration so populate slots according to the server manual for correct channel operation. Ensure the BIOS is current enough to recognise the speed and capacity.

Low-voltage operation with no heat spreader

At 1.1 V the module draws minimal power and runs cool without a heat spreader in normal server workloads. Passive cooling from chassis airflow is sufficient for typical duty cycles. The unbuffered design adds no extra electrical load on the memory controller.
