Lenovo ThinkSystem ST250 V3 upgrade

This 32 GB kit contains two 16 GB DDR5 ECC UDIMM modules built for the Lenovo ThinkSystem ST250 V3 tower server. The memory runs at 5600 MT/s with CL46 latency and operates at 1.1 V. It adds 32 GB of error-correcting capacity to compatible configurations.

Unbuffered ECC design

The modules are unbuffered ECC UDIMMs, so they plug directly into the server's DDR5 slots without a register. Each stick uses a 1Rx8 organisation and major-brand Samsung, Micron or Hynix chips. No heat spreader is fitted, leaving a low-profile form factor for dense chassis.

Verify DDR5 ECC UDIMM support

Confirm that your ST250 V3 motherboard accepts DDR5 ECC UDIMMs at 5600 MT/s and 1.1 V before ordering. Check the number of free 288-pin slots to ensure the two-module kit can be installed. This kit is not suited for systems that require registered or non-ECC memory.

Questions about this item

Will the 288-pin DDR5 modules need any cleaning or component replacement over time?

The modules have no heat spreader and no moving parts, so no routine cleaning or component replacement is required.

What limits sustained throughput first on the 5600 CL46 kit?

The CL46 latency at 5600 MT/s sets the primary ceiling for sustained data rate.

How much heat and power do the 1.1 V 1Rx8 sticks produce during all-day server operation?

Each 16 GB rank runs at 1.1 V without a spreader, so thermal output stays low and power draw remains minimal under continuous load.
