Precision 5820 Tower Workstation

The Dell Precision 5820 is a mid-tower desktop built for professional workloads. It ships with an Intel Xeon W-2245 eight-core processor running at 3.9 GHz with a 4.7 GHz turbo frequency. The system includes 256 GB of DDR4 2933 MHz registered ECC memory and a 2 TB PCIe NVMe solid-state drive. An Nvidia Quadro P4000 graphics card with 8 GB GDDR5 provides four DisplayPort outputs for multi-monitor setups.

Installation and common issues

The workstation arrives fully assembled with Windows 11 Pro pre-installed and digitally activated. Adding or replacing memory uses the eight DDR4 slots; the board supports a maximum of 256 GB, which this unit already reaches. The 950 W 80 Plus Gold power supply handles the installed components, but the physical length of the Quadro P4000 may limit additional full-length cards. Ensure the chassis side panel secures properly to maintain airflow through the CPU and GPU coolers.

256 GB DDR4 memory ceiling

The platform caps at 256 GB across its eight slots, so this configuration leaves no room for future RAM upgrades. Buyers who anticipate larger datasets or virtualisation clusters should note this limit before purchase. The 2 TB NVMe drive offers fast primary storage, yet only one M.2 slot is populated; secondary drives would require 2.5-inch or 3.5-inch bays. The Xeon W-2245 uses the LGA 2066 socket, tying the CPU to this generation.

Questions about this item

How do I verify the Xeon W-2245 is running at its 4.7GHz turbo speed after setup?

Open Task Manager's Performance tab and watch the CPU frequency climb toward 4.7GHz while running a heavy single-threaded load such as Cinebench or a large compile job.

What components are included and what must I purchase separately for the Precision 5820 Tower?

The tower ships with the Xeon W-2245, 256GB DDR4 ECC memory (8x 32GB), 2TB NVMe SSD, Quadro P4000 with four DisplayPort outputs, 950W 80 Plus Gold PSU and Windows 11 Pro. A monitor, keyboard and mouse are not included.

Should I choose the 256GB DDR4 2933MHz configuration or a lower-capacity option for the Precision 5820?

The 256GB (8x 32GB) kit fills all eight slots at the rated 2933MHz speed and matches the workstation's maximum supported memory, so it is the right choice for memory-intensive workloads.
