Precision 5820 tower for compute-heavy workloads

The Dell Precision 5820 is a mid-tower workstation built around an Intel Xeon W-2145 eight-core processor running at 3.70 GHz with a 4.5 GHz turbo frequency. It ships with 128 GB of DDR4 2666 registered ECC memory in a four-module configuration and a 2 TB PCIe NVMe solid-state drive. An Nvidia Quadro P4000 graphics card with 8 GB GDDR5 memory drives up to four DisplayPort monitors. Windows 11 Pro 64-bit is pre-installed and digitally activated.

Check power, memory slots

The system includes a 950 watt 80 Plus Gold power supply rated at 90 percent efficiency, so verify that your mains circuit can sustain the load. The motherboard provides eight DDR4 slots with a 256 GB maximum, leaving four slots free for future expansion. The Quadro P4000 occupies a full-height, double-width PCIe slot; confirm your rack or desk enclosure has enough depth and airflow for a card of that length. The LGA 2066 socket limits CPU upgrades to the same platform generation.

Steel chassis with tool-less access and quad

The black steel mid-tower chassis uses tool-less latches for side-panel removal and drive-bay access, simplifying hardware swaps during maintenance windows. Front I/O includes USB ports and audio jacks; rear I/O adds the Intel i219 gigabit Ethernet port and Realtek ALC3234 high-definition audio. The Quadro P4000 provides four native DisplayPort connectors, enabling multi-monitor arrays without adapters. Integrated 950 watt supply cables are routed through a grommeted channel for tidy cable management.

Questions about this item

What comes inside the Dell Precision 5820 box and do I need to buy a monitor separately?

The tower includes the Xeon W-2145 processor, 128GB DDR4 ECC memory, 2TB NVMe SSD, Quadro P4000 graphics card with four DisplayPort outputs, 950W 80 Plus Gold power supply and Windows 11 Pro. A monitor is not included and must be purchased separately.

Which memory configuration does this 128GB model use and can I add more later?

It is populated as 4x 32GB DDR4 2666MHz registered ECC modules. The board has 8 slots and supports up to 256GB, so four additional slots remain free for future upgrades.

What does the 3.7GHz base clock with 4.5GHz turbo mean for real workloads on this 8-core Xeon?

The W-2145 runs at 3.7GHz base frequency and can boost to 4.5GHz on active cores, giving strong single-thread speed for CAD and simulation tasks while all 8 cores sustain high throughput for rendering and compute jobs.
