DELL Precision 5820 Tower Workstation Xeon W-2155 10 Core 256GB DDR4 1TB NVMe Quadro P5000

Precision 5820 Tower Workstation

The Dell Precision 5820 Tower is a mid-tower workstation built around a 10-core Intel Xeon W-2155 processor running at 3.3 GHz with a 4.5 GHz turbo frequency. It ships with 256 GB of DDR4 2666 MHz registered ECC memory populated across eight slots and a 1 TB PCIe NVMe solid-state drive. The system includes an Nvidia Quadro P5000 graphics card with 16 GB GDDR5X memory and four DisplayPort outputs, plus Windows 11 Pro pre-installed.

Build Integration and Expansion

The chassis uses an LGA 2066 socket and supports up to 256 GB of total memory, leaving no vacant DIMM slots in this configuration. A 950 W 80 Plus Gold certified power supply rated at 90 percent efficiency delivers power to the CPU, GPU and storage without requiring an external brick. Integrated Intel i219 Gigabit Ethernet and Realtek ALC3234 audio handle networking and sound, while the Quadro card provides four DisplayPort connections for multi-monitor setups.

Sustained Load Behaviour

Under continuous workloads the Xeon W-2155 maintains its base 3.3 GHz clock across all ten cores, with turbo headroom available when thermal conditions allow. The Quadro P5000’s 256-bit memory interface and 16 GB GDDR5X frame buffer support extended rendering and compute sessions without throttling. Registered ECC memory corrects single-bit errors on the fly, preserving data integrity during long simulations or overnight batch jobs.
