DELL Precision 5820 Tower Xeon W-2235 3.8GHz 32GB DDR4 2TB NVMe Quadro P4000 Windows 11 Pro

Precision 5820 Xeon workstation

The Dell Precision 5820 Tower is a mid-tower workstation built around an Intel Xeon W-2235 six-core processor running at 3.8 GHz with a 4.6 GHz turbo. It ships with 32 GB of DDR4 2933 MHz registered ECC memory in four 8 GB modules and a 2 TB PCIe NVMe solid-state drive. An Nvidia Quadro P4000 graphics card with 8 GB GDDR5 and four DisplayPort outputs drives multi-monitor setups. Windows 11 Pro is pre-installed.

Installation notes and common issues

The chassis uses a standard mid-tower layout with tool-less drive bays and a side panel that lifts off after removing two thumbscrews. Memory slots are colour-coded for quad-channel population; install modules in matched sets of four to keep ECC functioning. The 950 W 80 Plus Gold power supply has fixed cables, so route the 8-pin CPU and dual 6+2-pin GPU leads before seating the motherboard. Verify the Quadro P4000 auxiliary power connector is fully latched — loose seating is the most frequent cause of no-post on first boot.

Suited for professional visualization.

This configuration suits engineers and designers running CAD, BIM or DCC applications that benefit from certified Quadro drivers and ECC memory stability. The six-core Xeon and 32 GB RAM handle moderate simulation datasets, but buyers who need more storage bandwidth or higher core counts for large-scale rendering should look at dual-socket platforms. The single GPU slot and 950 W PSU also limit multi-GPU expandability for deep-learning workloads.
