Lenovo ThinkSystem ST50 V3 Entry Tower Server

The Lenovo ThinkSystem ST50 V3 is an entry tower server built for small-business workloads. It ships with an Intel Xeon E-2456 six-core processor running at 3.20 GHz with a 5.1 GHz turbo frequency. The system includes 16 GB of DDR5 ECC UDIMM memory at 4400 MHz and a 300 W power supply. No storage drives are installed.

Suited for general-purpose file.

This configuration suits offices that need a quiet tower form factor with ECC memory protection and room to grow. It is not for buyers who want pre-installed drives or hardware RAID beyond RAID 0/1. It is not for deployments requiring redundant power supplies or rack-mount rails. It is not for workloads demanding more than one physical processor.

Memory scales to 128 GB across four DIMM slots

The four DDR5 slots support Lenovo TruDDR5 ECC UDIMMs at 4400 MHz, giving comfortable headroom for virtualisation or database caching. Storage expansion uses SATA III interfaces with onboard RAID 0/1 support. Three PCIe slots provide add-in card flexibility: one PCIe 5.0 x16 slot at 75 W and two PCIe 4.0 x4 open-ended slots at 25 W each. Network connectivity includes dual 1 GbE ports plus a dedicated management port.

Questions about this item

Which storage drives must I supply because the ST50 V3 ships without any installed?

The server includes no hard drive or SSD, so you must add SATA III drives yourself; the onboard controller supports RAID 0 and RAID 1 for those drives.

Will my existing PCIe 4.0 add-in card work in the ST50 V3 expansion slots?

Yes — the tower provides three slots: one PCIe 5.0 x16 at 75 W and two PCIe 4.0 x4 open-ended at 25 W each, all full-height half-length.

How can I verify the Xeon E-2456 is running at its 5.1 GHz turbo after setup?

Enter the UEFI or use an OS monitoring tool to confirm the processor reaches 5.1 GHz under load; the base frequency is 3.20 GHz with six cores.
