Tower server for general-purpose workloads
The Lenovo ThinkSystem ST45 V3 7DH51003NA is a 4U tower server built around a single AMD EPYC 4244P 6-core processor running at 3.80 GHz. It ships with 32 GB of TruDDR5 memory and a 300 W Gold power supply. The AMD PRO-665 chipset provides an onboard 6 Gb SATA controller in AHCI mode with no RAID capability. No drives are installed.
Suits small offices and branch sites needing
This system fits buyers who need a compact tower with ECC memory support and basic PCIe expansion. It does not suit buyers who need hot-swap drive bays, redundant power supplies, or dual-processor capability. The two DIMM slots limit memory to 64 GB maximum. Only one full-height half-length PCIe 3.0 x16 slot at 75 W and one x1 slot at 25 W are available for add-in cards.
Memory ceiling decided by two DIMM slots
The board provides two DIMM sockets that accept Lenovo TruDDR5 ECC UDIMMs at 5600 MHz. Maximum supported capacity is 64 GB. If the workload requires more memory than 64 GB, this platform cannot meet the requirement.

Questions about this item
How much heat and power draw should I expect from the fixed 300W Gold power supply when the EPYC 4244P runs continuously?
The server ships with a single fixed 300W Gold-rated power supply; the 6-core EPYC 4244P at 3.80 GHz and 32 GB of TruDDR5 draw well within that budget under sustained load, so fan noise stays low in a typical office environment.
Which storage drives and controller do I need to add before the ST45 V3 can boot an operating system?
No drives are installed; you must supply 3.5-inch SATA HDDs up to 8 TB each or a 2.5-inch SATA SSD up to 960 GB, and the onboard 6 Gb SATA controller in AHCI mode will recognise them without a separate RAID card.
Can I keep using my existing PCIe 3.0 add-in cards such as a GPU or NIC in the two expansion slots?
Yes — slot 1 is a PCIe 3.0 x16 full-height half-length slot rated for 75 W, and slot 3 is a PCIe 3.0 x1 full-height half-length slot rated for 25 W, so most legacy PCIe 3.0 cards will fit and operate normally.
