Precision 5820 Xeon Workstation

The Dell Precision 5820 Tower is a mid-tower desktop built around an Intel Xeon W-2155 processor with ten cores running at 3.30GHz base and 4.5GHz turbo. Sixteen gigabytes of registered ECC DDR4 2666 memory and a 1TB PCIe NVMe solid-state drive provide fast, error-corrected storage. An Nvidia Quadro P4000 graphics card with 8GB GDDR5 memory drives up to four DisplayPort monitors. Windows 11 Pro 64-bit is pre-installed for professional software compatibility.

Sustained Load Performance

A 950-watt 80 Plus Gold power supply rated at 90 percent efficiency delivers stable power during extended rendering or simulation tasks. The Xeon W-2155 maintains turbo frequencies across its ten cores while the registered ECC memory corrects single-bit errors without interrupting workflow. The Quadro P4000's 256-bit memory bus feeds the GPU steadily, and the tower chassis allows continuous airflow to keep component temperatures controlled during long compute sessions.

Build and Connectivity

The black mid-tower chassis houses an LGA 2066 motherboard with eight DDR4 slots supporting up to 256GB total memory for future expansion. Four DisplayPort outputs on the Quadro P4000 enable multi-monitor arrays without adapters. Integrated Intel i219 Gigabit Ethernet and Realtek ALC3234 high-definition audio handle wired networking and sound directly on the board. Tool-less access simplifies drive or memory upgrades when project demands grow.

Questions about this item

How loud or hot does the 950 W 80 Plus Gold power supply run when the Xeon W-2155 and Quadro P4000 are under sustained load?

The 950 W 80 Plus Gold unit is rated for 90 % efficiency, so it wastes less energy as heat and its fan typically stays at lower RPM during long render or compute sessions.

Which display cables must I already have to use the Quadro P4000's four DisplayPort outputs?

The card provides four DisplayPort connectors, so you need DisplayPort cables or active DisplayPort-to-HDMI/DVI adapters for each monitor you plan to attach.

Will my existing DDR4 2666 ECC RDIMMs work alongside the two factory 8 GB modules in the eight available slots?

Yes, the board has eight DDR4 2666 slots and supports up to 256 GB of registered ECC memory, so compatible RDIMMs can be added to the pre-installed pair.
