Kit composition and target system

This kit provides 64GB of DDR5 memory in four 16GB modules, validated for the Lenovo ThinkSystem ST50 V3 tower server. It suits administrators expanding capacity in that specific platform.

Mechanical and electrical interface

Each stick is a 288-pin unbuffered UDIMM without a heat spreader, running at 1.10V. The standard DDR5 pinout ensures straightforward insertion into the server’s four DIMM slots.

Thermals, noise and power

Operating at 1.10V with CL46 timing, the modules draw minimal power and generate little heat. No active cooling is required, keeping acoustic impact negligible in the tower chassis.

Questions about this item

Does DDR5 5600 PC5-44800 run at 5600 MT/s on the Lenovo ThinkSystem ST50 V3?

Yes, the kit is rated DDR5 5600 (PC5-44800) and will operate at 5600 MT/s when the server memory controller supports that speed.

Will four 288-pin UDIMM modules fit the ThinkSystem ST50 V3 DIMM slots?

The kit contains four 288-pin DDR5 ECC UDIMMs; the ST50 V3 has four UDIMM slots, so the kit fills all available slots.

What BIOS step is often missed when installing this ECC UDIMM kit?

After seating all four modules, enter BIOS and verify that ECC is enabled and the memory frequency shows 5600 MT/s; some systems default to a lower speed until manually confirmed.
