Professional Workstation Configuration

The Lenovo ThinkStation P620 is a tower workstation built for CAD, 3D rendering, engineering and creative production. It runs an AMD Ryzen Threadripper PRO 3945WX with 12 cores and 24 threads at 4.0 GHz base and 4.30 GHz boost. Installed memory is 16 GB across 8 DIMM slots supporting 8-channel DDR4 ECC RDIMM. Graphics are handled by an NVIDIA RTX A2000 card. A 1000 W power supply drives the system.

Installation and Common Issues

The unit arrives as a fully assembled tower with Windows 11 Pro pre-installed, so no internal build steps are required for the base configuration. Adding memory or storage means opening the chassis and populating the 8-channel DDR4 slots or the two built-in PCIe Gen 4 NVMe M.2 slots. A frequent issue is forgetting to enable ECC in the BIOS after installing RDIMM modules. Another is leaving the second NVMe slot unused when the 1 TB drive fills with active project files.

PCIe Gen 4 Storage and Expansion Limits

The platform provides two onboard PCIe Gen 4 NVMe M.2 slots and additional PCIe Gen 4 expansion slots for GPU, networking or further NVMe scaling. Bandwidth is shared across the CPU lanes, so populating multiple high-speed devices can reduce per-slot throughput. The 1000 W supply sets a practical ceiling on total add-in card power draw. Mechanical clearance in the tower chassis also limits the length and thickness of secondary graphics or accelerator cards.

Questions about this item

How do I confirm the workstation is running the Threadripper PRO 3945WX at its 4.0 GHz base frequency after setup?

Open Task Manager or a hardware monitor and verify the CPU shows 12 cores, 24 threads and a 4.00 GHz base clock under load.

What storage drives and graphics card are included, and what must be sourced separately?

The unit ships with a 1 TB NVMe M.2 SSD, a 2 TB 7200 rpm HDD and an RTX A2000 12 GB card; no other drives or GPU are required.

Which memory configuration suits a 3D rendering workload on the 8-channel DDR4 platform?

Start with the installed 16 GB and add matched DDR4 ECC RDIMMs to fill all eight slots for full 8-channel bandwidth.
