Precision 5820 workstation overview

The Dell Precision 5820 Tower is a mid-tower desktop built around an Intel Xeon W-2135 six-core processor running at 3.7 GHz with a 4.5 GHz turbo frequency. It ships with 16 GB of DDR4 2666 registered ECC memory, a 2 TB PCIe NVMe solid-state drive and an NVIDIA Quadro P5000 graphics card with 16 GB GDDR5X memory. Windows 11 Pro is pre-installed for professional workloads.

Compatibility checklist

Verify that your workflow can use registered ECC DDR4 modules at 2666 MHz, because the board has eight memory slots supporting up to 256 GB total. The CPU uses the LGA 2066 socket, so any cooler or upgrade must match that mounting pattern. The Quadro P5000 provides four DisplayPort outputs, so ensure your monitors accept that interface or plan for adapters. The included 950 W 80 Plus Gold power supply handles the factory configuration.

Build integration

The mid-tower chassis houses the 950 W power supply, freeing external space and delivering 90 percent efficiency at typical loads. Four DisplayPort connectors on the graphics card drive multiple displays without extra hardware. Eight DIMM slots leave room for memory expansion up to the 256 GB limit using DDR4 2666 registered ECC modules. Integrated Intel i219 gigabit Ethernet and Realtek ALC3234 audio handle networking and sound without additional cards.

Questions about this item

What is included in the box and what must I buy separately?

The tower ships with the Xeon W-2135 processor, 16 GB DDR4 2666 ECC memory in two 8 GB modules, a 2 TB M.2 NVMe SSD, the Quadro P5000 16 GB GDDR5X graphics card with four DisplayPort outputs, a 950 W 80 Plus Gold power supply and Windows 11 Pro. No monitor, keyboard or mouse are supplied.

Which memory configuration should I choose for this workstation?

The system has eight DDR4 2666 slots and supports up to 256 GB of registered ECC memory. The installed 16 GB uses two slots; add matching 8 GB or 16 GB ECC modules to fill the remaining six slots for best performance.

What does the 3.7 GHz base clock with 4.5 GHz turbo mean in daily use?

The six-core Xeon W-2135 runs at 3.7 GHz under sustained loads and can boost to 4.5 GHz on fewer active cores, giving strong single-thread speed for CAD and simulation while keeping all cores stable for rendering.
