Lenovo ThinkSystem ST50 DDR4 kit

This 16 GB kit contains two 8 GB unbuffered DIMMs built for the Lenovo ThinkSystem ST50 when it is equipped with an Intel Pentium processor. The modules run at DDR4 2400 with CL17 timings and 1.2 V operation. They are non ECC and use a 2Rx8 rank layout.

Sustained workload behaviour

Under continuous load the memory maintains its rated 2400 MT/s speed because the ST50 platform with a Pentium CPU does not push the controller beyond that frequency. The 1.2 V supply keeps power draw modest during long compute sessions. No heat spreader is fitted so airflow across the sticks matters for thermal stability.

Installation notes

Insert the two modules into the available 288 pin slots; the system supports four sockets and a 64 GB maximum. The kit is validated only for non ECC Pentium configurations so ECC only or mixed ECC setups will not work. Faster rated modules will clock down to 2400 automatically.

Questions about this item

Will the 1.2V DDR4 2400 modules run hot or loud inside a ThinkSystem ST50 under continuous load?

The kit operates at standard 1.2V DDR4 voltage with no heat spreader; it adds no active cooling and produces no noise of its own.

What must the ThinkSystem ST50 already have for this 2x8GB kit to function?

The server must use an Intel Pentium CPU, run non-ECC memory, and provide free 288-pin DDR4 DIMM slots — the kit is validated for that exact configuration.

If the ST50 currently holds slower DDR4 DIMMs, how will this 2400 CL17 kit behave?

Faster memory clocks down to the speed supported by the installed processor, so the new modules will run at the system’s optimal rate without compatibility issues.
