Precision 5820 Xeon workstation

The Dell Precision 5820 Tower is a mid-tower workstation built around an Intel Xeon W-2145 eight-core processor running at 3.7 GHz with a 4.5 GHz turbo frequency. It ships with 64 GB of DDR4 2666 MHz registered ECC memory, a 1 TB PCIe NVMe solid-state drive and an NVIDIA Quadro P4000 graphics card with 8 GB of GDDR5 memory. Windows 11 Pro is pre-installed and digitally activated.

Installation and common issues

The system arrives fully assembled so only peripheral cables and a monitor need connecting. Memory upgrades use the eight DDR4 slots and support up to 256 GB total when populated with compatible registered ECC modules. The 950 W 80 Plus Gold power supply provides ample headroom for the installed Quadro P4000 and additional storage, but verify physical clearance for longer add-in cards before purchasing upgrades.

Capacity and headroom

The 64 GB DDR4 configuration handles large datasets, virtual machines and multi-application workloads comfortably, with headroom to reach the 256 GB maximum via the four remaining slots. The 1 TB NVMe drive offers fast boot and project-file access, though users with extensive media libraries or simulation caches will need secondary storage. The Quadro P4000 drives four DisplayPort monitors and suits professional 3D and CAD tasks, while heavier GPU compute or ray-tracing workloads will exceed its 8 GB GDDR5 frame buffer.

Questions about this item

How can I confirm the Xeon W-2145 is running at its 3.7 GHz base clock and 4.5 GHz turbo after I assemble the system?

Open Task Manager's Performance tab or a hardware monitor such as HWInfo and verify the CPU frequency shows 3.70 GHz at idle and ramps to 4.5 GHz under load.

What components are included and which common items must I source separately?

The tower ships with the Xeon W-2145, 64 GB DDR4 2666 ECC in four 16 GB modules, a 1 TB NVMe SSD, a Quadro P4000 with four DisplayPort connectors, a 950 W 80 Plus Gold power supply and Windows 11 Pro; you will need to provide a monitor, keyboard and mouse.

Should I choose the 64 GB DDR4 2666 configuration or plan to expand toward the 256 GB maximum later?

The board has eight DDR4 slots and supports up to 256 GB total; starting with the factory 64 GB leaves four free slots for future registered ECC modules if your workload grows.
