Precision T5820 Xeon workstation

The Dell Precision T5820 is a mid-tower desktop built around an Intel Xeon W-2155 processor with 10 cores running at 3.3 GHz and a 4.5 GHz turbo. It targets engineers, designers and analysts who need certified stability for CAD, simulation or rendering workloads. The system ships with Windows 11 Pro pre-installed and activated. Buyers who require a mobile form factor or consumer-grade gaming features should look elsewhere.

128 GB ECC memory and Quadro P4000 graphics

Four 32 GB DDR4 2666 registered ECC modules fill half the eight available slots, leaving room to reach the 256 GB maximum. The Nvidia Quadro P4000 adds 8 GB GDDR5 memory on a 256-bit bus and provides four DisplayPort outputs for multi-monitor setups. A single 2 TB PCIe NVMe SSD handles boot and active projects. Users who need additional internal hard drives or a different GPU architecture will have to source those parts separately.

Standard tower access with 950 W Gold supply

The mid-tower chassis opens with a side panel for straightforward access to memory slots, the M.2 drive and the full-height graphics card. The included 950 W 80 Plus Gold power supply delivers 90% efficiency for the configured components. Installers should verify that any added cards fit the available length and power budget. No monitor, keyboard or mouse is included in the package.

Questions about this item

How many DDR4 2666 slots remain free for future memory expansion?

The system has eight DDR4 2666 slots in total; four are occupied by the factory-installed 32 GB registered ECC modules, leaving four slots available for additional memory up to the 256 GB maximum.

What limits sustained CPU performance first — power delivery or thermal capacity?

The 950 W 80 Plus Gold power supply provides ample headroom for the 10-core Xeon W-2155, so thermal capacity of the mid-tower chassis becomes the practical limit during prolonged all-core workloads.

How loud is the workstation when the Quadro P4000 and Xeon run flat-out all day?

Dell’s thermal design targets office-friendly acoustics; under full load the fans ramp up but remain within the typical quiet workstation range, and the 90 % efficient power supply adds minimal extra heat or noise.
