Precision 5820 Xeon workstation
The Dell Precision 5820 tower workstation is built around a 10-core Intel Xeon W-2255 processor running at 3.7 GHz with a 4.7 GHz turbo frequency. It ships with 32 GB of DDR4 2933 registered ECC memory across four slots 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. The system includes a 950 W 80 Plus Gold power supply and Windows 11 Pro 64-bit.
Upgrading from older workstations
This configuration replaces ageing towers that rely on consumer-grade processors, non-ECC memory or mechanical hard drives. The jump is worth it when workloads demand certified drivers, error-correcting memory and sustained multi-core performance for rendering, simulation or large dataset analysis. The eight total memory slots allow future expansion up to 256 GB without replacing existing modules. The Quadro P4000 supports professional applications that require ISV certification and 10-bit colour pipelines.
Compatibility checks before ordering
Verify that your display cables match the four DisplayPort connectors on the Quadro P4000; no HDMI or DVI ports are present on the card. Confirm that your peripherals and network infrastructure work with the integrated Intel I219 gigabit Ethernet and Realtek ALC3234 audio. The mid-tower chassis requires adequate desk or floor space and airflow clearance for the 950 W power supply. Ensure your software licences are compatible with Windows 11 Pro 64-bit before deployment.

Questions about this item
What size power supply fits the Precision 5820 tower?
The workstation uses a Dell 950 watt 80 Plus Gold unit that is 90 percent efficient.
How is the Xeon W-2255 processor installed, and what step is often missed?
The CPU drops into the LGA 2066 socket; the critical step is applying thermal paste and seating the cooler evenly before locking the lever.
When will the 32GB DDR4 2933 memory need to be expanded or replaced?
The board has eight slots and supports up to 256 GB, so you can add modules later or swap to higher-capacity sticks when workloads grow.
