Precision 5820 Tower Workstation

The Dell Precision 5820 is a mid-tower workstation built for professional workloads. It runs on an Intel Xeon W-2155 processor with 10 cores operating at 3.3 GHz and a 4.5 GHz turbo frequency. The system includes 16 GB of DDR4 2666 registered ECC memory across eight slots and a 2 TB PCIe NVMe solid-state drive. An Nvidia Quadro P2000 graphics card with 5 GB GDDR5 memory provides four DisplayPort outputs. Windows 11 Pro 64-bit comes pre-installed.

Suited for CPU-intensive professional tasks

This workstation suits users who need strong multi-core CPU performance and certified professional graphics for CAD, rendering or simulation workloads. The registered ECC memory and 950 W 80 Plus Gold power supply support stable operation during long compute jobs. Buyers who need more than 16 GB of memory out of the box should note the 256 GB maximum capacity requires additional modules. Systems without integrated Wi-Fi or Bluetooth hardware require separate adapters for wireless connectivity. The single Quadro P2000 limits multi-GPU configurations.

10-core Xeon W-2155 defines compute capacity

The Intel Xeon W-2155 processor with 10 cores and 3.3 GHz base clock determines the workstation's primary compute capability. Its 4.5 GHz turbo frequency accelerates single-threaded tasks while the 10 cores handle parallel workloads. The LGA 2066 platform supports up to 256 GB of DDR4 2666 registered ECC memory across eight slots. This CPU specification is the key factor when matching the system to software licensing or performance requirements.

Questions about this item

How can I verify the Xeon W-2155 is running at its 3.3 GHz base and 4.5 GHz turbo speeds after I install Windows 11 Pro?

Open Task Manager and select the Performance tab to watch the live CPU frequency, or run a stress test such as Cinebench and confirm the all-core turbo reaches 4.5 GHz under load.

What components come inside the Precision 5820 tower and which essential item is not included?

The box contains the mid-tower chassis with a 950 W 80 Plus Gold power supply, the 10-core Xeon W-2155 processor, 16 GB of DDR4 2666 MHz registered ECC memory in two 8 GB modules, a 2 TB M.2 NVMe SSD, and the Quadro P2000 graphics card with 5 GB GDDR5 and four DisplayPort outputs; a monitor is not included.

Which memory configuration should I choose if I want to expand toward the 256 GB maximum supported by this workstation?

The system ships with two 8 GB DDR4 2666 MHz registered ECC modules occupying two of the eight slots; add identical registered ECC DIMMs in multiples of 8 GB to keep quad-channel performance and reach the 256 GB limit.
